Full textAbstract:
Opportunities are a core construct in the field of entrepreneurship. Despite recent advances suggesting the separation of ideas from opportunities, the field still suffers from conceptual deficiencies. This article builds on this distinction and leverages insights from creativity and innovation management literature to propose a framework that allows tracing the evolution of a venture from first insight to exploitation. It discusses real–time/longitudinal and retrospective measurement techniques from the fields of entrepreneurship, creativity, and innovation management to empirically capture the framework. Several research questions for future studies are provided, concluding with a discussion of implications for research and practice.

Purpose – The purpose of this paper is to investigate the managerial practices to assess value creation and value capture potential in longitudinal buyer-seller relationships, and proposes a framework for evaluating such potential for maximizing sales function efficiency. Design/methodology/approach – The research is based on an exploratory multi-case study with seven internationally operating companies from a variety of industries, with the aim of building the framework for sales opportunity management. The framework is then refined in eight workshops with 21 companies. Findings – The findings suggest that industrial companies need to develop new capabilities to efficiently manage value selling opportunities at different stages of the opportunity lifecycle. Research limitations/implications – The underlying sales approach of the research is proactive value selling in a service business context. The findings may not be generalizable into other sales contexts. Practical implications – The paper provides practicing managers with an actionable sales opportunity management framework for an effective management of sales quality. Originality/value – The research contributes to a previously unexplored area of sales management, and suggests a managerial practice linking strategy to implementation at the customer interface.

Capture and permanent geologic sequestration of biogenic CO2 emissions may provide critical flexibility in ambitious climate change mitigation. However, most bioenergy with carbon capture and sequestration (BECCS) technologies are technically immature or commercially unavailable. Here, we evaluate low-cost, commercially ready CO2 capture opportunities for existing ethanol biorefineries in the United States. The analysis combines process engineering, spatial optimization, and lifecycle assessment to consider the technical, economic, and institutional feasibility of near-term carbon capture and sequestration (CCS). Our modeling framework evaluates least cost source–sink relationships and aggregation opportunities for pipeline transport, which can cost-effectively transport small CO2 volumes to suitable sequestration sites; 216 existing US biorefineries emit 45 Mt CO2 annually from fermentation, of which 60% could be captured and compressed for pipeline transport for under $25/tCO2. A sequestration credit, analogous to existing CCS tax credits, of $60/tCO2 could incent 30 Mt of sequestration and 6,900 km of pipeline infrastructure across the United States. Similarly, a carbon abatement credit, analogous to existing tradeable CO2 credits, of $90/tCO2 can incent 38 Mt of abatement. Aggregation of CO2 sources enables cost-effective long-distance pipeline transport to distant sequestration sites. Financial incentives under the low-carbon fuel standard in California and recent revisions to existing federal tax credits suggest a substantial near-term opportunity to permanently sequester biogenic CO2. This financial opportunity could catalyze the growth of carbon capture, transport, and sequestration; improve the lifecycle impacts of conventional biofuels; support development of carbon-negative fuels; and help fulfill the mandates of low-carbon fuel policies across the United States.

Abstract. Many river basins throughout the world are increasingly under pressure as water demands keep rising due to population growth, industrialization, urbanization and rising living standards. In the past, the typical answer to meet those demands focused on the supply side and involved the construction of hydraulic infrastructures to capture more water from surface water bodies and from aquifers. As river basins have become more and more developed, downstream water users and ecosystems have become increasingly dependent on the management actions taken by upstream users. The increased interconnectedness between water users, aquatic ecosystems and the built environment is further compounded by climate change and its impact on the water cycle. Those pressures mean that it has become increasingly important to measure and account for changes in water fluxes and their corresponding economic value as they progress throughout the river system. Such basin water accounting should provide policy makers with important information regarding the relative contribution of each water user, infrastructure and management decision to the overall economic value of the river basin. This paper presents a dynamic water accounting approach whereby the entire river basin is considered as a value chain with multiple services including production and storage. Water users and reservoir operators are considered as economic agents who can exchange water with their hydraulic neighbors at a price corresponding to the marginal value of water. Effective water accounting is made possible by keeping track of all water fluxes and their corresponding hypothetical transactions using the results of a hydro-economic model. The proposed approach is illustrated with the Eastern Nile River basin in Africa.

Full textAbstract:
This article has two objectives: to critique the dominant opportunity discovery and creation literatures and to propose a new, critical realist–inspired analytical framework to theorise the causes, processes and consequences of entrepreneurial action – one that needs no concept of opportunity. We offer three reasons to support our critique of opportunity studies. First, there are important absences, contradictions and inconsistencies in definitions of opportunity in theoretical and empirical work that mean the term cannot signal a clear direction for theorising or empirical research. Our central criticism is that the concept of opportunity cannot refer simultaneously, without contradiction, to a social context offering profit-making prospects, to particular practices and to agents’ subjective beliefs or imagined futures. Second, a new definition of opportunity would perpetuate the conceptual chaos. Third, useful concepts to capture important entrepreneurial processes are readily available, for instance, combining resources, creating new ventures and achieving product sales, which render a concept of opportunity superfluous. Instead, we conceptualise entrepreneurial action as investments in resources intended to create new goods and services for market exchange emergent from the interaction between agential, social-structural and cultural causal powers.

Over the last decade, there have been many changes in the field of political analysis at a global level. Through social networking platforms, millions of people have the opportunity to express their opinion and capture their thoughts at any time, leaving their digital footprint. As such, massive datasets are now available, which can be used by analysts to gain useful insights on the current political climate and identify political tendencies. In this paper, we present TwiFly, a framework built for analyzing Twitter data. TwiFly accepts a number of accounts to be monitored for a specific time-frame and visualizes in real time useful extracted information. As a proof of concept, we present the application of our platform to the most recent elections of Greece, gaining useful insights on the election results.

The authors provide a framework and a set of research propositions that capture and extend current theory on information processing from advertisements. The integrative attitude formation model includes antecedent levels of ability, motivation, and opportunity (AMO), processing of brand information, cognitive and emotional responses, brand attitude formation processes, and brand attitude. Key features of the framework are (1) a more complete, integrative discussion of needs and motivation, (2) a more precise specification of processing mechanisms than currently is proposed in two-routes-to-persuasion models, (3) inclusion of a new typology of emotional and cognitive responses explicitly linked to the levels of brand processing, and (4) a discussion of how alternative attitude formation models correspond to each level of brand processing. To assess the relative advantage of the framework, the authors compare the model with previous integrative models and discuss its implications for related research streams.

Approaches to accelerate innovation have become more integrated and systemic over time, such as Agricultural Innovation Systems and co-innovation. Primary Innovation is a New Zealand co-innovation programme in which innovation is conceived as being ‘co-produced’ by stakeholders who contribute their unique knowledge to solving a problem or realizing an opportunity. In co-innovation, cyclical processes of planning, doing, observing and reflecting enable innovation to emerge from interactive learning among stakeholders. In this article, we argue that when flexibly applied and adapted to capture dynamics typical in systems innovation projects, the log frame approach and logical frameworks have considerable utility to support evaluation for both learning and accountability and for identifying and addressing institutional logics, which lead to system innovation. We demonstrate this for the case of Primary Innovation and compare our experiences with the limitations and solutions suggested by other recent researchers when applying logic models, logical frameworks, programme theories or theories of change as part of an ‘adapted accountability framework’.

Full textAbstract:
Maritime transportation has traditionally been a crucial part of world economy. Countries which are connected to a seaboard or major river will have the opportunity to develop a port which can provide access to water transportation. When there are two or more ports in the nearby area, customers tend to prefer to use the facilities available at the main ports since goods handling and transfer are more efficient and economical. Nearby ports which receive little or no special support from the government, and are thus overshadowed by the larger ports which inevitably leads to the loss of their market share (Tongzon 2002; Magala 2008). These shadow ports must find ways to survive and prosper in a competitive environment. Indeed, both main and regional ports could become shadow ports of another nearby port.
Generally, ports will grow if they succeed in providing profits to the sellers and the related third-party service providers and delivering value to the buyers (Robinson 2002b; 2003). There are few studies regarding the port competition for growth and survival between two nearby main ports. Difficulties begin to arise if a new main port is established because of limitations or inefficiencies of an existing port which could not provide satisfactory services to customers or contribute to the economic activity of the nation (Limskul 1998). Therefore, with the loss of their market and lack of support from their governments, the existing ports need to find a way to survive. These ports are metaphorically under the shadow of the nearby superior port. Most of these shadow ports are regional ports which are situated near main ports. On the other hand, and of interest to this study, there is a situation where there are two main ports (where one port was built after the other) situated near each other.
Thailand, is one of the countries that have a significant part of its economy reliant on water transportation. Here, the situation of having two main ports close to each other has arisen. These two ports are Bangkok Port (the older main port which is in Bangkok), and Laem Chabang Port (the more recently established main port which is in Chonburi province).
This study focuses on using the Opportunity Capture framework to understand and explain how a main port can manage to grow in the proximity of a nearby predominant main port. The original framework was suggested by Magala (2004). Ansoff’s Matrix (Ansoff 1957) and the Noticing, Collecting and Thinking (NCT) model (Seidel 1998) were used with this framework in an attempt to capture the opportunity for shadow ports.
Port experts in Thailand were interviewed regarding their opinion on potential policies that the shadow ports should pursue in order to be viable and competitive. Five categories of experts include personnel from the Thai government, the shipping- related council/federation, logistics providers, relevant business sectors and respected academics who are researching in this area. Semi-structured interviews as a qualitative approach toward the development and understanding were based on the Opportunity Capture framework. The data from the interviews were analyzed qualitatively using the NCT framework in order to highlight important criteria and underlying factors required to create policies for the shadow port. Six findings were extracted from the analysis, and the strategic solution for Bangkok Port was derived from the use of the Opportunity Capture framework and evaluated with Ansoff’s Matrix. The findings and the strategy suggested here could be implemented to increase the competitiveness of Bangkok Port and, finally, to allow the port to grow if that is the direction that Thai government wishes for the port.
Finally, this study found that Bangkok Port could gain more profit by adapting itself into a coastal port since there is a plan to establish a coastal port at Laem Chabang Port. Hence, Bangkok Port could use this opportunity to increase its competitiveness by becoming a domestic hub for distributing imported goods inside the country, and by collecting export goods before shipping them to Laem Chabang Port via coastal ships. With this solution, Bangkok Port could gain profit from such strategic directions by: (i) providing the services of domestic port, (ii) offering rental office for third-party logistics providers to use inside the port, and (iii) offering a container freight stations (CFS) service to open and close containers using existing equipment and skills.

Full textAbstract:
AbstractThe overall goal of AgeCap is to contribute to increased wellbeing and participation in life for the older population. While there are several ways to meet this challenge, AgeCap has chosen the capability approach, which focuses on a subjective perceived health- and ability-related perspective, rather than on disease or disabilities. The understanding of capability used within the centre is based on the work of the philosopher and economist Amartya Sen, described as the individual’s ability to perform actions in order to reach goals he or she has reason to value (Sen A. The idea of justice. Belknap Press of Harvard University Press, Cambridge, MA, 2009). The capability approach focuses on what people are able to do and to be – their capabilities – and on their freedom of choice to perform those actions. AgeCap’s multidisciplinary setting was an opportunity to adopt the capability approach within its research. Nevertheless, it also created challenges in establishing a common view of what capability is, and how to apply the concept in collaborations across several different research fields. Thus, at an early stage during the setting up of the Centre, it was decided that a conceptual framework aiming to capture a shared view of capability in ageing should be developed. In addition, in order to facilitate the application of the capability approach within the research setting and make it more accessible to different target groups within society, it was later proposed that a graphic illustration of the AgeCap framework of capability should be created. This chapter describes the conceptual framework and graphic illustration that were developed by the Communication Group in collaboration with the Steering Committee, Principal Investigators, other researchers within AgeCap and the company Explain Artist. Central concepts include available resources, conversion factors, capability set, freedom of choice, goals of value and justice. The purpose of the conceptual framework is mainly to serve as a platform for researchers to use in any way they find relevant from their own perspective. Furthermore, the graphic illustration was developed in order to facilitate the application of the capability approach within AgeCap and make our research more accessible to society in order to dismantle the wall between researchers, older people and the general public.

AbstractDigitalization has tremendously challenged how international opportunities are created and captured. Inspired by researches in the field of both entrepreneurship and international business, this study provides a comprehensive framework toward the impact of digital technologies (DTs) on opportunity pursuit in foreign markets. We identify two perspectives of DTs, i.e., DTs as ‘driving force’ and DTs as ‘disrupting force,’ which characterize DTs as a catalyst of experiential knowledge acquisition, and as a factor altering the relative significance of experiential knowledge to opportunity pursuit, respectively. By bridging these two perspectives with the notion of market-specific knowledge and general knowledge within internationalization process theory, some arguments with regard to what specific influences DTs play on international opportunity pursuit are further introduced. We hope this study can potentially offer some nuances to both practitioners as well as the research in the interaction of digitalization and international opportunity.

This chapter provides specific research examples on the neurobiology of mental illness—using psychosis as a case in point—that may begin to rise to the level of “facts,” or at least “almost facts” or strong “hints,” about important etiological mechanisms that need to be explained to capture key components of at least some facets of mental illness. These examples are then used to illustrate where computational psychiatry approaches may help. In particular, there is an opportunity to provide links across different levels of analysis (e.g., behavior, systems level, specific circuits and even genetic influences) in ways that can lead to a more unified framework for understanding the apparent multitude of impairments present in psychosis, which may in turn lead to the identification of new treatment or even prevention targets. This chapter also discusses some of the known conundrums about the etiology of mental illness that need to be accounted for in computational frameworks, including the presence of heterogeneity within current diagnostic categories, the vast degree of comorbidity across current diagnostic categories, and the need to reconceptualize the dimensionality versus categorical nature of mental illness.

This chapter explores the experiences of four virtual interns working with organizations tackling social issues in Ecuador, Morocco, South Africa, and Vietnam. These internships provided a unique opportunity to develop and apply the social, emotional, and academic development (SEAD) competencies of self-awareness, self-management, social awareness, relationship skills, and responsible decision-making. Schlossberg's transition theory provides a framework for transitioning to another culture and cultural mapping is used as a tool to identify, plan, and mitigate differences in cultural orientations between interns and colleagues in their host countries. The chapter draws upon student narratives and reflections, and supervisor feedback to capture what they learned and the challenges they faced as they completed their virtual internships. The results contribute to the literature related to the development of SEAD competencies through virtual internships for high school and college students.

This chapter suggests a new framework for thinking about the role of informal mentoring in higher education based on the persistently changing role of education. The chapter provides the findings from a qualitative research study that examined how the lived experiences of three novice professors guided their engagement in informal mentoring opportunities. The study offers evidence to capture how engagement in mentoring opportunities improved the quality of teaching. With each mentoring opportunity, these three professors gained knowledge and skills that they integrated into their classrooms to be more effective teachers. The conclusions address the following areas: the importance of previous lived experiences as a catalyst for in engaging in mentoring opportunities; the importance of mentoring having an informal structure, one where they controlled the learning direction; the nature and ramifications of the informal versus formal aspects of this process; and the findings in this study align with Kolb's learning theory.

Developing high quality teachers is at the center of education reform and previous research has highlighted, high quality in-service teacher professional development leads to improved instruction, student learning, and ultimately promotes social equity. Using an Interpretive Phenomenological Analysis (IPA) theoretical framework, the voices and experiences of educators in Haiti were captured. This study reveals the following themes: 1) an opportunity for self-improvement, 2) an avenue for improving students learning, and 3) an approach to contributing to colleagues' development. An understanding of these themes from a cross-cultural perspective is provided with the objective that school personnel, receiving this population of students will develop an understanding of Haitian student's educational experiences.

The passing of the Violence Against Women Reauthorization Act (VAWRA) (2013) has provided further opportunities to gain awareness of the impact of Intimate Partner Violence. The Act incorporated more funding for research and preventative programs for IPV throughout the country. The Act also incorporated protections for individuals encompassing sexual orientation and gender identity. This created an opportunity for scholars to provide literature focusing on various aspects of IPV pertaining to causes, reports, and prevention resources. It is critical to capture data on this population and be aware of their experiences to inform future policy, research methodologies, theoretical frameworks, and best practices when working to provide services to the community. Reports of the experiences from individuals in the LGBTQ community are alarming to review. Although the 2013 VAWRA was passed to provide more resources and prevention of these experiences it is evident that there are striking concerns of experiences of intimate partner violence in the LGBTQ community. Therefore, this chapter provides a systematic review capturing studies published after the passing of the 2013 VAWRA to provide content on LGBTQ individuals experiences of IPV, the criminal justice system, and resources for prevention.

Abstract The Introduction nuances our familiar conception of interwar architectural history as fundamentally split between ‘Modernism’ and ‘Traditionalism’ by exploring the German Expressionist Erich Mendelsohn’s first visit to Britain in 1930. It uses this occasion to look at common critical concerns for both ‘camps’ and proposes an alternative explanatory framework that captures prevalent anxieties, dynamic attempts at problem-solving, and new modes of criticism and practice, especially civic design and the emergence of the interwar ‘architect-planner’. The second part of the Introduction reframes the 1920s and 1930s in terms of post-war reconstruction. From 1917, the energies of the state, industry, and institutions were turning towards reconstruction—economic, social, and physical. The professions and their corporate bodies were also prompted to reflect. Architects anxiously seized the opportunity to engage with bold and radical ideas to strengthen, or even remake, their own profession and definitively resolve tensions which had dogged them for decades. They began to think more corporately and to champion a professional ideal which ultimately overrode the sometimes internecine rhetoric of architectural discourse—the ‘battle of the styles’—which has been overemphasized in existing accounts of the period. All architects had designs on democracy; they sought to shape and co-opt it, and to preserve the precarious privileges of professional status. This is the driving thesis of the book and the Introduction ends with an overview of its structure.

I continue to be surprised and pleased by the dramatic growth of interest in and applications of genetic algorithms (GAs) in recent years. This growth, in turn, has placed a certain amount of healthy "stress" on the field as current understanding and traditional approaches are stretched to the limit by challenging new problems and new areas of application. At the same time, other forms of evolutionary computation such as evolution strategies [50] and evolutionary programming [22], continue to mature and provide alternative views on how the process of evolution might be captured in an efficient and useful computational framework. I don't think there can be much disagreement about the fact that Holland's initial ideas for adaptive system design have played a fundamental role in the progress we have made in the past thirty years [23, 46]. So, an occasion like this is an opportunity to reflect on where the field is now, how it got there, and where it is headed. In the following sections, I will attempt to summarize the progress that has been made, and to identify critical issues that need to be addressed for continued progress in the field. The widespread availability of inexpensive digital computers in the 1960s gave rise to their increased use as a modeling and simulation tool by the scientific community. Several groups around the world including Rechenberg and Schwefel at the Technical University of Berlin [49], Fogel et al. at the University of California at Los Angeles [22], and Holland at the University of Michigan in Ann Arbor [35] were captivated by the potential of taking early simulation models of evolution a step further and harnessing these evolutionary processes in computational forms that could be used for complex computer-based problem solving. In Holland's case, the motivation was the design and implementation of robust adaptive systems, capable of dealing with an uncertain and changing environment. His view emphasized the need for systems which self-adapt over time as a function of feedback obtained from interacting with the environment in which they operate. This led to an initial family of "reproductive plans" which formed the basis for what we call "simple genetic algorithms" today, as outlined in figure 1.

Full textAbstract:
Abstract Gas lift operations are highly dependent on data quality and team competence to operate the asset efficiently. Traditional methods for gas lift well surveillance and diagnostics rely on wireline services, a method with growing constraints to adapt to constantly evolving well and operational challenges. The Well Intervention-less Tracer Surveillance System (WITSS) provides a cost effective, comprehensive approach to well surveillance without the reliance on tools entering the well. This results in reduced HSE risks and no associated deferred production. This paper describes a pilot implementation to evaluate the adequacy and accuracy of this technology in the context of ADNOC Onshore gas lift producers. The objective is to evaluate its performance against conventional method data sets and assess the reproducibility of data where no reference existed. The 10 well pilot included both accessible and obstructed wells. Data from the custom designed modular portable kit used for executing the surveillance activities, was analyzed and compared against conventional flowing gradient surveys with full data consumption in well models for comprehensive nodal analysis and opportunity identification. For this pilot, ten wells were surveyed twice using the WITSS method. Results were compared to traditional methods acquired through wireline surveys for accessible wells, and against established multi-phase flow correlations for obstructed wells. The pilot confirmed the WITSS method is as accurate as conventional gauge measurements in mapping pressure and temperature profiles in gas lifted wells. The WITSS method provided additional insight on accurate gas consumption based on the assessment of total gas lift utilization per well and allowed comprehensive model calibration and well performance definition. It also identified potential integrity issues via identification of primary injection at designed stations and secondary unwanted injection sites. Continuous compositional gas analysis of both injected and produced gas streams provided additional verification for analyzing gas lift injection performance. It also highlighted a change in fluid compositional analysis opening discussions for material selection review of the assets. Production uplift identified from 50% of wells was compliant with the reservoir management strategy. The value proposals of flow stabilization through gas lift valve re-calibrations and replacements, adjustment of injection flow rate and further controls on injection pressure management are under process for implementation. Full field scale up scenario is under preparation.

Abstract Many IOC and NOC organizations have and continue to be face with the challenge of establishing a corporate standard for measuring production performance across their producing assets. The difficulty with this challgenge comes from reporting localized production, managing production shortfalls, and identifying opportunities to increase production. These are three critical elements of production excellence or production performance programs. This paper presents a solution for this challenge. This novel solution uses the choke model or limit diagram to integrate existing portions of the production performance framework; i. e., shortfall production management, opportunity identification workshops, and well potential calculations. The challenge is to duplicate these elements in a standard way across 12 active producing assets at different geographical locations, with diverse operating cultures, hydrocarbon types, contractual frameworks, and engineering criteria. Within three years all assets were sharing the same basis for Production Excellence program (Px) with strict reporting discipling enabled by common corporate system. During the same period the overall production efficiency increase by 3% adding 1.1 MMBOE into the tanks. In addition to the production baseline sustainability, other major benefits included the standardization of oil production loss classification and production opportunities identification workshop to keep the discipline of identifying production potential to reflect the everchanging field conditions. This paper will present the integration of the Px program as the main endevoar to make it a portion of the operating culture and the proposed method to capture and share the performance gains. Additionally, a tremendous effort was made to build some of the elements directly into the production data management systems in the local operating assets to enable the corporate reporting system to read any source of data. These data are then used as a business intelligence application reporting accessible via smart and interactive dashboards.

Full textAbstract:
Abstract Engineers use three tools for analyzing fluid flows: analytical, experimental, and numerical. Thorough analyses involve all three tools to inform design decisions or postmortem investigations. However, few undergraduate fluid mechanics lab experiences expose students to the simultaneous application of these tools to a common problem. In this paper, we discuss a set of exercises and lab activities spanning multiple weeks to study a cylinder in a crossflow, providing students with their first experience in the use and comparison of analytical, experimental, and numerical tools for studying a fluid flow. The analytical approach involves the solution derived for potential (inviscid) flow around a cylinder. While no novel examples or analytical approaches are used to teach this portion of the experience, this idealized flow solution is used as a comparison for experimental and numerical lab activities. The experimental approach was initially designed to leverage low-cost microcontrollers and MEMS-based pressure sensors while reinforcing mechatronics and related programming content used in previous courses. Over four years of use and iteration, it has evolved from instructors supplying only a C++ library for the pressure sensors, a wiring diagram, and a rough programming framework to a simplified MATLAB interface that abstracts away many of the low-level commands required to complete the lab exercise. This range of interfaces and experiences allows instructors flexibility in their own implementation and lab goals. The latest iteration includes the use of a hot-wire anemometer, which must be calibrated by students, and allows for data capture and analysis of the resulting vortex street formation and Strouhal number. The numerical approach uses a transient 2D planar analysis for flow around a cylinder and leverages a commercial computational fluid dynamics software, Ansys, for which there are free student versions. Students are provided with an instructor-built flow domain and mesh capable of providing a mesh-independent solution. Students choose solvers, set boundary conditions, run simulations, and process resulting data to compare with analytical and experimental results. A transient analysis is used to capture the effects of vortex formation on the coefficient of lift and to calculate and compare the system’s Strouhal number with that found from the physical experiment. Students are challenged throughout the experience, from completing classic problems such as the lift force on a Quonset hut, to automating sensor positioning and data collection, to simulating a transient fluid flow. A concerted analysis of this relatively simple geometry affords students the opportunity to use analytical, experimental, and numerical tools to compare drag forces, pressure distributions, and transient flow behaviors.

Full textAbstract:
Abstract Waterfront movement in fractured carbonate reservoirs occurs in micro-fractures, corridors and interconnected fracture channels (above 5 mm in size) that penetrate the carbonate reservoir structure. Determining the fracture channels and the waterfront movements within the flow corridors is critical to optimize sweep efficiency and increase hydrocarbon recovery. In this work, we present a new deep reinforcement learning algorithm for the optimization of sensor placement for waterfront movement detection in carbonate fracture channels. The framework deploys deep reinforcement learning approach for optimizing the location of sensors within the fracture channels to enhance waterfront tracking. The approach first deploys the deep learning algorithm for determining the water saturation levels within the fractures based on the sensor data.. Then, it updates the sensor locations in order to optimize the reservoir coverage. We test the deep reinforcement learning framework on a synthetic fracture carbonate reservoir box model exhibiting a complex fracture system. Fracture Robots (FracBots, around 5 mm in size) technology will be used to sense key reservoir parameters (e.g., temperature, pressure, pH and other chemical parameters). The technology is comprised of a wireless micro-sensor network for mapping and monitoring fractures in conventional and unconventional reservoirs [1]. It establish a wireless network connectivity via magnetic induction (MI)-based communication since it exhibits highly reliable and constant channel conditions with sufficient communication range in the oil reservoir environment. The system architecture of the FracBots network has two layers: FracBot nodes layer and a base station layer. A number of subsurface FracBot sensors are injected in the formation fractures that record data affected by changes in water saturation. The sensor placement can be adapted in the reservoir formation to improve sensor data quality, as well as better track the penetrating waterfronts. They will move with the injected fluids and distribute themselves in the fractures where they start sensing the surrounding environment's conditions and communicate data, including their location coordinates, among each other to finally send the information in multi-hop fashion to the base station installed inside the wellbore. The base station layer consists of a large antenna connected to an aboveground gateway. The data collected from the FracBots network will be transmitted to the control room via aboveground gateway for further processing. The results exhibited resilient performance in updating the sensor placement to capture the penetrating waterfronts in the formation. The framework performs well particularly when the distance between the sensors is sufficient to avoid measurement interference. The framework demonstrates the criticality of adequate sensor placement in the reservoir formation for accurate waterfront tracking. Also, it shows that itis a viable solution to optimize sensor placement for reservoir monitoring. This novel framework presents a vital component in the data analysis and interpretation of subsurface reservoir monitoring system for carbonate reservoirs. The results outline the opportunity to deploy advanced artificial intelligence algorithms, such as deep reinforcement methods, to optimally place downhole sensors to achieve best measurement success, and track the waterfronts as well as determine sweep efficiency.

Full textAbstract:
Abstract Soft piezoelectric composites (SPCs) show great promise as next-generation energy harvesting materials, with the potential to outperform piezoelectric polymers with limited elastic stretchability (e.g., PVDF) and traditional brittle piezoelectric ceramics (e.g., PZT). Presently, however, SPCs remain an emerging class of materials, with relatively few comprehensive investigations holistically exploring their synthesis, electro-mechanical property characterization, large-strain constitutive modeling, and non-linear mechanics and dynamics. In this paper, we take first steps toward addressing this compelling research opportunity. A three-component SPC is synthesized, consisting of an ultra-stretchable Ecoflex silicone rubber matrix, micron-sized PMN-PT piezoelectric particles, and CNTs that serve as inter-particle conductive “bridges.” Mechanical, electrical, and coupled electro-mechanical properties are quantified. A thermodynamically consistent, fully non-linear, finite-strain constitutive model is presented, based on a gentle adaptation of an existing transversely isotropic non-linear electro-elastic constitutive framework. Use of the particle orientation vector as an independent variable leads to two-way coupling between mechanics and electricity not present in the isotropic counterpart of this constitutive model. A prototype free energy function with the electric field as the independent variable is proposed that captures the essential physics. This free energy leads to a compact set of non-linear, finite-strain constitutive equations whose mathematical forms have direct analogue to the linear, small-strain theory of piezoelectricity.

Full textAbstract:
The North American pipeline industry is facing a time of significant expansion over the next decade as a result of market demand and technology advancements that have fundamentally shifted supply and demand patterns in North America. While recent commodity prices have softened, the need for pipeline infrastructure may only be somewhat delayed, still allowing industry opportunity to improve practices in a number of areas. The INGAA Foundation and the Canadian Energy Pipeline Association (CEPA) Foundation have a number of initiatives underway in this respect; in particular, there is an emphasis on improving quality in all aspects of the pipeline construction process. One of the initiatives, described in this paper, relates to the compilation of a guide and body of knowledge for inspection practices and captures best practices as they relate to third party inspection during the construction process. The outlined approach is intended to have two main philosophical underpinnings: it must complement existing practices, training and certification, and it must remain user friendly and practical to use. The main challenge in capturing best practices in this area lies in striking an appropriate balance between specific guidance regarding third party inspection and overly prescriptive, specific company practices. This is further complicated due to the broad range of topics and information required that is not always consistently documented across member companies. In light of these realities, the approach for the Practical Guide for Pipeline Construction Inspection was to align material required to perform an inspection task tightly to the sequential construction process to allow an intuitive layout for new industry entrants. Once a working group, representing both US and Canadian Operators and Services providers was established, a detailed table of contents was developed and agreed to by the group. Using this simple framework, available Member Company information was then reviewed, assessed and captured in detail for inclusion in the guide. The information took a range of forms ranging from specifications, manuals to training documents and modules. Significant collaboration, through working sessions, with Subject Matter Experts (SMEs), used to review, revise and supplement the content, as required. Overall, this approach provided a technically sound guide, addressing gaps in codified industry knowledge, while remaining relevant and accessible for most users. Upon completion, this body of knowledge will be available for member companies to use immediately, and potentially, as a basis for training, individual study, and the further refinement of existing industry certification.

Full textAbstract:
Patients need the ability to accurately and efficiently communicate their preferences across outcome domains to their healthcare providers.1-7 No existing system provides an efficient and timely approach to collect and communicate patient preferences across outcome domains to support shared decision making (SDM) in orthopaedic practice.2-4,8-19 The overarching goal of this research is to design, build, and test an app that collects baseline patient preferences and health status across orthopaedic outcomes and reports this information to the provider for use in patient care. A core component of the app is a Direct-Weighting (DW) preference assessment approach, originated from our prior research, and applied in a touchscreen based interactive design. It is envisioned that patients will use the app after scheduling a first visit to a surgeon for a new orthopaedic condition. Direct weighting (DW) approaches calculate patient-specific preference weights across outcomes by asking patients to disperse portions of a hypothetical “whole” across outcomes in a manner that reflects a patient’s preferences.20 DW has low respondent burden but it requires respondents to make “implicit” comparisons which may be difficult to conceptualize.20 However, the DW approach has become generally accepted in the quality-of-life literature and it has been shown that patients dividing up pieces of a “pie” across quality-of-life domains yields valid representations of patient preferences across the domains.20-22 However, the DW approach has not been validated with specific clinical scenarios using a clinically focused set of outcomes or by using a mobile software app. Drawing on prior research, we iteratively design and develop the app with input from prior DW research, informaticians, and clinicians. We use a qualitative approach to pilot test the app with 20 first-time visit patients presenting with joint pain and/or function deficiency. Participants were interviewed about their outcome preferences for care, used the app to prioritize outcome preferences, answered interview questions about their experience using the app, and completed a mHealth App Usability Questionnaire (MAUQ). Interview questions focused on the utility and usability of the mobile app for communicating with their provider, and capability of the app to capture their outcome preferences. Results validated five core preference domains, with most users dividing their 100-point allocation across 1-3 domains. The tool received moderate to high usability scores. Patients with older age and lower literacy found the DW approach more difficult in terms of allocating 100 points across 5 domains. Suggestions for DW interface interaction improvement included instantiation of a token/points oriented DW preference scoring methodology rather than a 1-10 sliding scale approach for improved preference weighting cognition and SDM with a provider. As more patient reported outcome (PRO) apps hit the marketplace across a broad spectrum of health conditions, these results provide evidence for a DW approach and interactive design for patients to communicate their treatment preferences to their providers.References:1.Baumhauer JF, Bozic KJ.

Full textAbstract:
Abstract Interest in CCS project development is accelerating in SE Asia, driven by the need to monetize emission-intensive assets in the region while complying with increasingly ambitious GHG emissions targets. Depleted hydrocarbon fields represent an attractive storage option for early CCS project due the enhanced understanding of the reservoir, its dynamic behavior, and proven storage capability. Re-use of existing infrastructure also presents the potential to reduce both project costs and time to first injection, however, these brownfield sites also carry significant risk to the long-term, safe containment of injected CO2 through risk of leakage via legacy wells. A methodology is presented in this paper to investigate the risk-reward balance of developing a depleted gas field as a storage site in the Gulf of Thailand. A screening process to assess all abandoned, suspended, and active wells is used to identify wells with re-use potential as CO2 injectors or CO2 plume monitoring wells, and those which represent a leakage risk to the project. A set of legacy well risk identifiers is generated for the field based on well construction records, descriptions of current well barriers, well utilization history, and current best practice guidelines. Southeast Asia has significant remaining reserves of oil and gas, and coal, and an active liquefied natural gas (LNG) export industry. The region's energy demand is increasing rapidly and is forecast to continue to grow over the next decades (World Economic Forum, 2019). To date, fossil fuels have supplied nearly 90% of this growth in the demand for energy in the region (IEA, 2021). To meet this growing energy demand, several new gas projects are under development across Southeast Asia, but many of these are associated with high CO2 gas fields where the produced gas contains significant (up to 70% by volume) CO2 (GCCSI, 2020). In Thailand, where nearly 94% of the primary energy is met by fossil fuels (BP Statistical Review, 2022), the energy sector represents the biggest contributor (74% in 2013) to the country's greenhouse gas emissions (GHG; UNFCCC, 2020). However, as per the nationally determined contribution to the United Nations Framework Convention on Climate Change (UNFCCC), Thailand intends to reduce its GHG emissions by at least 20% from projected business as usual levels by the year 2030 (UNFCCC, 2020). Carbon capture and storage (CCS) represents one option to help meet this increased demand in fossil energy while also reducing GHG emissions. An approach which is gaining traction across the region is to utilize the high concentrations of CO2 stripped out of the raw gas streams at gas processing plants and, instead of venting to atmosphere, the CO2 can be compressed, dehydrated, and transported to suitable long-term storage locations. Depleted oil and gas fields form an attractive opportunity for long-term storage of CO2 due to the wealth of both static and dynamic knowledge available from appraisal through production activities. Depleted fields also have the advantage that they have a working primary seal for hydrocarbons, which has been proven over geological time and so can be considered, in general, to carry low risk of leakage through geological means. Brownfield sites can, however, also represent a challenge to project success through an increased risk to the containment of the injected CO2 due to the presence of legacy wells. These existing wells represent a variable risk to containment depending on well age and type, well history, well design, and plug and abandonment methodology applied. This paper presents the outcomes of a CO2 storage feasibility study for a depleted gas-condensate field in the Gulf of Thailand. The main aims of the study were to:1) identify the project risk associated with the integrity of the field legacy wells, and 2) to evaluate the potential for well re-use for the CO2 injection project. Reusing an existing field offers new life to an otherwise end-of-life asset, inching towards decommissioning and site closure. As commercial scale CO2 storage in depleted hydrocarbon fields represents a ‘First of a Kind’ project, the feasibility study is designed to evaluate the current status of the field and surface facilities with respect to CO2 injection and long-term storage. As a feasibility study, the focus of the technical work was to identify any ‘showstoppers’ which might indicate that the selected site was not suitable for long-term CO2 storage and, if sufficient positive storage indicators were identified, to select the most appropriate options for progression into a Concept Selection study in which more detailed engineering studies will be completed.

Full textAbstract:
Most of the world’s remaining tropical forests lie in areas that are customarily managed and/or legally owned by Indigenous Peoples and local communities. In the context of climate change and global efforts to protect and enhance the capacity of forests to capture and store greenhouse gas emissions, the question of who owns the trees and the carbon stored therein is paramount. Clarifying this question is crucial, both for the future of the planet, and for up to 1.7 billion people worldwide who rely on forests for their livelihoods. This brief presents a review of the nominal progress made in the national-level laws and regulations that govern the carbon trade and define the rights of parties —across a sample of 24 countries in Africa, Asia and Latin America. These countries collectively hold more than 50 percent of global tropical and subtropical forests. This brief also examines the design and establishment of safeguard mechanisms concerning benefit sharing, providing redress and resolution to disputes related to carbon-based schemes, and the operationalization of carbon registries for each of these countries.
