The technology of sending signals by way of modulation as well as electromagnetic radiation with waves that travel through the air and produce sound is the meaning of radio. In broadcasting, scripts and writing are needed so that they are pleasing to the ear and also structured. In the process of writing copywriting, Style is needed so that the advertisements shown on the radio can be absorbed by listeners and are moved to buy the product being advertised and cause an action. Because radio only relies on audio, the sentence structure must be precise and there is a script structure that is being discussed so that it is good. Using research methods sourced from books and the internet. The essence of Copywriting style and the structure of discussion scripts on radio is to hone writing and editing skills in radio scripts.

Full textAbstract:
The study examined radio family planning messages with particular reference to the nature of the audience influence on communication content by using a chat program on radio in a developing society. The study adopted content analysis research method with a purposive sampling technique and used a radio script having six items for analyses. Results showed that there were more family planning segments for women than for men and, there were more family planning for drugs/pills and materials/implantation than for injection. In addition, there were side effects in the use of family planning just as there were quite a number of frequently asked questions except for condoms-fiesta/kiss. This paper concludes that radio scripts/messages for family planning programs should accommodate more topics/segments of family planning for men and women, specifically, natural methods should be included. Furthermore, radio family planning messages should focus more on the benefits of family planning and specifically the benefits of contraceptive pill and post pill emergency should be examined. Other formats of programs should be employed in the campaign for family planning messages on radio, and development communicators and content developers of radio family planning scripts should explore more areas to make radio messages more robust.

Radio RRI Madiun is a government-owned public broadcasting agency whose function is to present actual, precise, and reliable information. Radio is one of the mass media that is experiencing rapid technological advances. The purpose of this study is to analyze the journalistic language used to write news broadcast scripts. In this study, the authors used data collection techniques such as the stages of observation, interviews, and documentation. The research location is at LPP RRI Madiun City. In radio news media, writers and broadcasters have a strong collaboration to produce news that is accurate and can be well-received by the public. The use of language in accordance with journalistic rules is the most important aspect of writing news scripts that will be broadcast by radio institutions. The results showed that the news script already contained the rules of journalistic language, but there were some sentence points that used a foreign language or did not use language in everyday life so the cloud community still understood a little of what was conveyed by the broadcaster.

In spite of the prominence acquired by dialogues among characters in creating a series, we cannot ignore that radio speech can be represented in turn by the narrators’s presence. For this reason, in the present article the emblematic Taxi Key detective series has been selected as an object of study, in order to determine the narrators’s appearance percentage in the series episodes, the narrator’s typology that prevails and the main functions that plays in this fictional product. It is an exploratory study in which descriptive and inferential analyzes have been made from Taxi Key original radio scripts. The results of the study reveal that narrator’s presence reaches the most significant prevalence in the episodes of the sample, being the autodiegetic narrator who stands as the most frequent type of narrator. Providing contextual information, acting as a nexus and transition device between scenes and assessing the characters or incorporating them on stage are the narrator’s functions that prevail in this series that remained almost twenty years on Radio Barcelona network. Keywords: Series; Taxi Key; Radio Script; Detective Fiction Genre; Storyteller; Autodiegetic.

Previous issue date: 2015-03-26This dissertation centers around the radio narrative work authored by José Medina in the years 1946 and 1947, in the city of São Paulo, which allows one to investigate the relationship between memory and consumption. The research material includes five radio play scripts presented in two different media: radio and newspaper. The general objective is to present the narrative structures and melodramatic production logics found in the work of José Medina, and thereby bring to mind certain habits and consumption practices, both symbolic and material, in São Paulo, in 1946 and 1947. Specific objectives include presenting the mediatic production of José Medina besides his radio production, and study the radio language used at the time. The question used as the basis for the research is intended to show how the narrative construction and the radio language evidence the memory of certain habits and consumption practices in São Paulo in 1946 and 1947. As this is a historical research that counts on a broad documental corpus, the method used was the document analysis and bibliographic survey. The main sources of the survey to gather together the corpus were the Medina family files and the Public Archives of the State of São Paulo. Theoretical references include scholars such as Paul Zumthor, Murray Schafer, Marlyse Meyer, Ian Watt, Edgar Morin, Jerusa Pires Ferreira, Mônica Rebecca Ferrari Nunes, Ecléa Bosi, Néstor García Canclini, Jesús Martín-Barbero and Roger Silverstone, and other researchers that were used as guidance for these reflections. Results point to the intertwining of communications, consumption, and memory, looking at radio listening and the reading of radio plays scripts in the newspaper as symbolic assets that represent media consumption and position the listener/reader in time and space.
Esta pesquisa tem como tema as construções narrativas radiofônicas de autoria de José Medina durante os anos de 1946 e 1947, em São Paulo, que permitem observar a relação entre memória e consumo. O corpus da pesquisa inclui cinco roteiros de peças radiofônicas apresentados em duas mídias: rádio e jornal. O objetivo geral é apresentar as estruturas narrativas e as lógicas de produção melodramática, presentes na obra de José Medina e, por meio delas, trazer a memória de certos hábitos e práticas de consumo, material e simbólico, em São Paulo, entre os anos de 1946 e 1947. Os objetivos específicos são: apresentar a produção midiática de José Medina, além da radiofônica; e estudar a linguagem radiofônica utilizada na época. A questão que norteou a pesquisa propõe responder de que modo a construção narrativa e a linguagem radiofônica evidenciam a memória de certos hábitos e práticas de consumo em São Paulo entre 1946 e 1947. Por se tratar de uma pesquisa histórica que dispõe de um amplo corpus documental, a metodologia aplicada foi a análise documental e a pesquisa bibliográfica. As principais fontes pesquisadas para compor o corpus foram o arquivo particular da família de Medina e o Arquivo Público do Estado de São Paulo. O referencial teórico inclui pensadores como Paul Zumthor, Murray Schafer, Marlyse Meyer, Ian Watt, Edgar Morin, Jerusa Pires Ferreira, Mônica Rebecca Ferrari Nunes, Ecléa Bosi, Néstor García Canclini, Jesús Martín-Barbero e Roger Silverstone, além de outros teóricos que contribuem para estas reflexões. Os resultados apontam para o entrelaçamento entre comunicação, consumo e memória, entendendo a escuta do rádio e a leitura de roteiros de peças radiofônicas em jornal também como bens simbólicos que, em si, representam o consumo midiático e situam o ouvinte/leitor no tempo e no espaço.

The strength of broadcasting media becomes weaker because of the attacks from TV, computers and Internet. Nowadays broadcasting programs contain few children’s radio dramas. However, people’s efforts and dedication still complete step by step the indispensable jigsaw puzzle in children’s literary history though the children’s literary stage has declined gradually. The Children’s Radio Dramas of the Children’s Studio by National Educational Broadcasting Station receiving authorization from Ministry of Education conveys principles about morality, lives, ethics and patriotism to contemporary children and also the script of radio dramas which fits and gets close to children is based on these principles. The thesis concludes that differences from children’s mental learning states and educational essentials cause the children’s disparity of perception toward the theme of radio dramas. It really relies on school’s ingenious design and assistance to continue the children’s radio dramas with resources on hand.

Full textAbstract:
Corpus linguistics research on audio description (AD) – the verbal rendering of visual information generally targeted at people with visual impairment – has focused on film and museums. The present corpus gathers opera AD scripts from the Liceu opera house (Bacelona) and Teatro Real (Madrid), and sorts them into four subcorpora, two devoted to AD throughout the performance and two comprising audio introductions (AI). I set to interrogate where opera AD falls in the spoken-written language continuum. The results suggest that all subcorpora are of a high lexical density, and in terms of lexical variation, the standardised type-token ratio remains below 50%. The mean sentence and word length, and the Flesch-Szigriszt readability results lead us to place the AIs closer to written language than ADs.

AbstractFluorine-19 MRI shows great promise for a wide range of applications including renal imaging, yet the typically low signal-to-noise ratios and sparse signal distribution necessitate a thorough data preparation.This chapter describes a general data preparation workflow for fluorine MRI experiments. The main processing steps are: (1) estimation of noise level, (2) correction of noise-induced bias and (3) background subtraction. The protocol is supplemented by an example script and toolbox available online.This chapter is based upon work from the COST Action PARENCHIMA, a community-driven network funded by the European Cooperation in Science and Technology (COST) program of the European Union, which aims to improve the reproducibility and standardization of renal MRI biomarkers. This analysis protocol chapter is complemented by two separate chapters describing the basic concept and experimental procedure.

Full textAbstract:
AbstractFibrillar collagen is an abundant extracellular matrix (ECM) component of interstitial tissues which supports the structure of many organs, including the skin and breast. Many different physiological processes, but also pathological processes such as metastatic cancer invasion, involve interstitial cell migration. Often, cell movement takes place through small ECM gaps and pores and depends upon the ability of the cell and its stiff nucleus to deform. Such nuclear deformation during cell migration may impact nuclear integrity, such as of chromatin or the nuclear envelope, and therefore the morphometric analysis of nuclear shapes can provide valuable insight into a broad variety of biological processes. Here, we describe a protocol on how to generate a cell-collagen model in vitro and how to use confocal microscopy for the static and dynamic visualization of labeled nuclei in single migratory cells. We developed, and here provide, two scripts that (Fidler, Nat Rev Cancer 3(6):453–458, 2003) enable the semi-automated and fast quantification of static single nuclear shape descriptors, such as aspect ratio or circularity, and the nuclear irregularity index that forms a combination of four distinct shape descriptors, as well as (Frantz et al., J Cell Sci 123 (Pt 24):4195–4200, 2010) a quantification of their changes over time. Finally, we provide quantitative measurements on nuclear shapes from cells that migrated through collagen either in the presence or the absence of an inhibitor of collagen degradation, showing the distinctive power of this approach. This pipeline can also be applied to cell migration studied in different assays, ranging from 3D microfluidics to migration in the living organism.

This chapter highlights the liberation of Paris, which had been something of a free-for-all for the press and an embarrassing debacle for army public relations. It mentions the Columbia Broadcasting System's (CBS) Charles Collingwood and its censorship officials for publishing a story that Paris was free two days before the Germans actually surrendered the city. Based on Collingwood's report, England's King George IV had also announced the liberation of Paris, which later forced officials of the Supreme Headquarters Allied Expeditionary Force (SHAEF) into the embarrassing position of having to contradict the monarch. The chapter talks about radio correspondents who broadcasted their stories using the Radio France transmitter in Rambouillet without first submitting their scripts for censorship. It recounts how the radio correspondents were immediately suspended by the SHAEF, charging that they had not gone to the Scribe for the required vetting of their copy.

Abstract Research and development have a complex interrelationship. Inventions are a product of enquiry and experimentation; likewise, new technologies may open up hitherto unforeseen avenues for investigation. Early progress in astronomy, for example, depended on underpinning mathematics, as well as more mundane technologies such as lenses, global navigation, and timekeeping. Developments in humanities research have likewise been accelerated with new discoveries via archaeology and techniques for deciphering ancient scripts. The military and commercial sectors have been particularly influential in R&D, sometimes driving research, sometimes utilizing research, and sometimes inadvertently contributing to research. The invention of the radio is considered as an example of commercial exploitation of underpinning science. After exploring radio, the chapter offers an overview of the more modern phenomenon where technological development sometimes outstrips its applicability—the ‘solution in search of a problem’ scenario.

"High Resolution Reservoir Simulator Driven Custom Scripts as the Enabler for Solving Reservoir to Surface Network Coupling Challenges." In Abu Dhabi International Petroleum Exhibition & Conference.

Abstract This paper presents a practical methodology of optimizing and building a detailed field surface network system by using the high-resolution reservoir simulator driven custom-made Python scripts to efficiently predict the future performance of the vast oil and gas-condensate carbonate field. All existing surface hydraulic tables are quality checked and lifting issue constraints corrected. Pressure losses at the wellhead chokes incorporated into the high-resolution reservoir simulator in the form of equation by using the custom scripts instead of a table format to calculate gas rate dependent pressure losses more precisely. Consequently, all 400+ surface production system manifolds, pipes and well chokes Horizontal Flow Performance (HFP) tables are updated and coupled to the reservoir simulator through Field Management (FM) controller which in turn generates Inflow Performance Relationship (IPR) tables for the coupled wells and passes them to solve the network. The methodology described in this paper applied for a complex field development planning of the Karachaganak. At present, reservoir management strategy requires constant balancing effort to uniformly spread gas re-injection into the lower Voidage Replacement Ratio areas in the Upper Gas-Condensate part of the reservoir due to reservoir heterogeneity. Additionally, an increase in field and wells gas-oil ratio and water-cut creates bottlenecks in the surface gathering system and requires robust solutions to decongest the surface network. Current simulation tools are not always effective due longer run times and simulation instability due to complex network system. As a solution, project-specific network balancing challenges are resolved by incorporating custom-made scripts into the high-resolution simulator. Faster and flexible integrated model based on hydraulic tables reproduced the historical pressure losses of the surface pipelines at similar resolution and generated accurate prediction profiles in a twice-quicker time than existing reservoir simulator. Overall, this approach helped to generate more stable production profiles by identifying bottlenecks in the surface network and evaluate future projects with more confidence by achieving a significant CAPEX cost savings. The comprehensive guidelines provided in this paper can aid reservoir modeling by setting up flexible integrated models to account for surface network effects. The value of incorporating Python scripts demonstrated to implement non-standard and project specific network balancing solutions leveraging on the flexibility and the openness of the modelling tool.

In ASME 2008 6th International Conference on Fuel Cell Science, Engineering and Technology. ASMEDC, 2008. http://dx.doi.org/10.1115/fuelcell2008-65139.
Full textAbstract:
The strong links between COMSOL and MATLAB offers a useful option for the self-automated geometrical optimization process in PEMFC, which overcomes the difficulties on geometry optimization in Computational Fuel Cell Dynamics based design. Geometry optimization of self-breathing PEMFC, including the channel-rib ratio at anode and the open ratio at the cathode side are investigated in order to improve the fuel cell performance. A sequential quadratic programming method is selected to deal with the constrained design problem, while the objective function is calculated by running the 3D simulation script of COMSOL in the MATLAB environment. Simulation results show that for the self-breathing PEMFC operating at 353K and 1 atm with a voltage of 0.7V, when the channel-rib ratio at anode side is fixed at 10%, the optimal open ratio of the self-breathing cathode is found to be 49.8%. While, when the open ratio at the cathode is set at 80%, the optimal channel-rib ratio is located at 34.7%. However, the differences in the current density are not significant when the channel-rib ratio at the anode is varied while maintaining the open ratio at 80% for the cathode side.

Full textAbstract:
The present work involves the development of a learning model for the analysis of data from telecommunication and social networks for devices that make voice calls and data sessions, using Business Intelligence concepts and tools. The paper has a multi/interdisciplinary character, calling for e-learning, telecommunication, database, programming, IT applications and social/business networks. Business Intelligence (BI) refers to those data analysis systems by integrating them into a platform that allows the association of information through data transformation operations. For this analysis to be effective, it is necessary to identify and define the required quality indicators (KPIs: Key Performance Indicators) and the desired associations with them, which can be made in the BI platform. The information extraction operations can be done in the SQL queries area or when data is uploaded to the BI platform, taking into account the following factors: database queries efficiency, transformation efficiency at BI platform level, and available hardware capacity for calculations. There is a balance between the volume of SQL queries, taking into account the complexity of the queries (number and type of joins) and the size of the files to be imported into the platform. Consideration may also be given to how new data is added to source files for the BI platform. The applications developed for this purpose allow the analysis of KPIs by applying filters that make easier to understand the general problems of an application and identify network areas where possible degradation or shortcomings are observed. Developing a solution for analyzing these aspects of radio measurements and comparing operators on various criteria for voice and data and application testing comes as a response to the need to be able to analyze and interpret a huge amount of data accumulated over very long periods (years) and to identify the main elements that can lead to improved network performance. BI analysis is addressed to business managerial levels for discovery of large deficiencies without analyzing each test, satisfying the need for interaction by allocating a minimum number of parameters associated with KPIs so that analysis and decisions taken consequently have a high impact for a company benefits. BI analysis is predominantly conducted in the telecommunications field, but the same principles can be used in other areas, and the way of working can be adapted to serve as a strong starting point in any type of analysis for which information is available at the level of a database. In order to be able to apply the BI analysis tools, databases containing information specific to the 2G, 3G and 4G technologies (GSM, WCDMA and LTE) have been developed. Databases contain tables populated with metrics representing information similar to those collected during telecommunication measurements (data generation is done through popular spreadsheet scripts with Excel support). Multiple SQL queries for denormalizing, aggregating, and transforming data have also been developed for use as a data source in the KPIs analysis, comparison, and interpretation process. In order to apply these data transformation queries in a format that facilitates further BI analysis, a C# application that exports the new content to a predefined area is made available to the BI environment (in text format). The new C# content is loaded into the QLIK Sense Desktop platform, a BI development environment where another set of data transformations, (defining legends to create geo-location features for elements) is loaded in this environment. The next step is to develop specific formulas, taking into account the new available structure to obtain KPIs with expected values and views for post-denormalization analysis. Two dashboards were developed for this purpose: voice and data tests. Configuring the development environment involves setting the connection to the location where the new content is placed, uploading these data, modifying them, creating formulas, identifying causes of value-based telecoms errors, creating a range for radio measurement values, and creating functions for geo-location of data using QLIK script syntax. It is defined a graphical interface by creating, where necessary, maps of geo-tagged data, filters, graphs, pivot tables, pie-charts, histograms, etc. across multiple display sheets, organized to contain the information specific to a particular analysis, thereby creating an analytical context in which the information required for use in the analysis is arranged adjacent, in the form of filters or graphs, the results being easier to interpret by introducing color coding formulas. The definition of special formulas and their application uses KPIs, and their development is carried out with a language specific to the development environment: QLIK Sense Desktop. Part of analyzing data in a BI environment is to interpret data and various configurations. Depending on who accesses such an environment, one can configure (in the web version) different access modes and set up visible information for each user so that a manager can access general performance sheets and an RF engineer can access specific performance sheets, both of which being designed to enhance the ability of each to interpret, decide, and improve the desired performance. Another important aspect is the low analysis time, due to the fact that the data automatically undergoes a transformation that initially had to be manually adapted. Automatic correlations that may go unnoticed, and there is also the ability to adapt and change over time. Increased efficiency comes from the fact that uncorrelated information in the database becomes correlated. BI applications refresh after each selected criterion so that the same graph shows different information if a single operator/service is selected. The paper contains detailed BI complex analysis examples for the video player in social networks: YouTube, Facebook, Twitter, Instagram, etc. In the BI environment, possible causes for the effects observed in the operations are performed, resulting in an easier interpretation of the results. This information can be valuable to departments such as Marketing/Sales, Network Operations Center, Optimization/Planning, etc. Data analysis by using a BI platform is useful when data sources are not directly correlated, allowing optimized visualization and identification of KPIs performance and metrics specifically defined for fast and efficient handling of data specific to mobile telecom operators and social networks or business networks.

In Vertical Flight Society 78th Annual Forum & Technology Display. The Vertical Flight Society, 2022. http://dx.doi.org/10.4050/f-0078-2022-17482.
Full textAbstract:
In this paper, an automated framework is presented to perform helicopter rotor blade planform optimization. This framework contains three elements, Dakota, ParBlade, and RCAS. These elements are integrated into an environment control tool, Galaxy Simulation Builder, which is used to carry out the optimization. The main objective of this work is to conduct rotor performance design optimizations for forward flight and hover. The blade design variables manipulated by ParBlade are twist, sweep, and anhedral. The multi-objective genetic algorithm method is used in this study to search for the optimum blade design; the optimization objective is to minimize the rotor power required. Following design parameter substitution, ParBlade generates the modified blade shape and updates the rotor blade properties in the RCAS script before running RCAS. After the RCAS simulations are complete, the desired performance metrics (objectives and constraints) are extracted and returned to the Dakota optimizer. Demonstrative optimization case studies were conducted using a UH-60A main rotor as the base case. Rotor power in hover and forward flight, at advance ratio = 0.3, are used as objective functions. The results of this study show improvement in rotor power of 6.13% and 8.52% in hover and an advance ratio of 0.3, respectively. This configuration also yields greater reductions in rotor power for high advance ratios, e.g., 12.42% reduction at advance ratio 0.4.

Full textAbstract:
This paper deals with the development of an optimizing technique based on Genetic Algorithms (GA), which can be applied to the optimization of an internal cooling system of turbine nozzles. An impingement cooling system with pins and air-discharging holes is selected as target cooling system to be optimized using a single-objective GA code developed in this study. The optimization is performed for several design parameters such as the impingement and discharging hole diameters, pin diameter and pin height. The computational grid is automatically generated and boundary conditions prescribed. A commercial CFD code is used to evaluate the target function, which is in the present case simply defined as the ratio between the averaged heat transfer coefficient multiplied by the wetted area and the pressure loss. A hybrid FORTRAN/UNIX shell script program controls the whole process of the optimization, leading to the successful achievement for finding an optimum configuration of the cooling system concerned.

Full textAbstract:
Wide gap brazing (WGB) is a cost effective and reliable means to repair gas turbine hot section components with defect sizes exceeding 0.3 mm. However, it has been shown that WGB joints of nickel-based superalloys suffer from reduced ductility and thermal fatigue life due to the presence of brittle intermetallics and porosities in the brazed joint. In order to disperse the brittle intermetallic compounds, potentially increase the ductility of the repaired region, and reduce the risk of the thermo-mechanical fatigue failure, elemental tungsten (W) was added to the braze additive filler alloy IN738 by mechanical alloying. The alloyed IN738 was then brazed with the addition of 30, 50 and 80 wt% of braze alloy (BNi-9). After brazing at 1200°C for 20 minutes, microstructural analysis of WGB joints showed a decreasing trend of discrete boride size and the amount of eutectic and script-shaped borides with the increases of W. The increase in the braze alloy to additive filler alloy ratio diminished the effect of W addition due the dissolution of W particulates.

Full textAbstract:
Abstract This paper demonstrates how a novel electromagnetic induction heating technology can be used to recover oil from the Athabasca oil sands of Alberta with minimal environmental impact. The paper compares the new technology to other electromagmetic heating technologies for oil sands, exhibits how electromagnetic induction heating is coupled to the reservoir, and addresses requirements of the new technology for economic production. The patent pending inductor design generates thermal energy in a reservoir model representing a 33 meter pay zone with properties for the lower McMurray formation in an area north of Fort McMurray within the Athabasca oil sands deposit. Electromagnetic energy is coupled to the reservoir in an iterative process that enables operators to monitor and control reservoir temperature, pressure, fluid production, and energy to oil ratio, to enhance recovery of heavy oil and bitumen. This is performed by interfacing commercial electromagnetic and reservoir simulators using an in-house coupling script. The results demonstrate an ultimate oil recovery factor of +70% with an energy to oil ratio lower than 200 kilowatt hour per barrel. This is less energy per barrel than the average energy required by steam assisted gravity drainage. Though not compulsory for the process, it is observed that oil recovery is improved with water injection. This is mainly because the amount of electromagnetic energy coupled to the reservoir correlates with water saturation in the near wellbore region. Water injection helps maintain water saturation levels and improves heat convection further into the reservoir. Nonetheless, there is no need for external water supply, because the volume of injected water required to improve oil recovery is comparable to the overall volume of water produced from the reservoir. Unlike other recovery methods, this technology is expected to have low energy intensity, zero emissions, and minimized land footprint leading to responsible bitumen recovery. This paper sheds light on the capability of an innovative clean energy technology to enhance bitumen recovery from the Athabasca oil sands in Alberta. The novel technology takes advantage of clean energy to recover oil at a lower energy to oil ratio than the average ratio achieved with steam injection methods.

Full textAbstract:
The flow field plate of a proton exchange membrane fuel cell (PEMFC) functions as electron conductor and provides the pathway for oxidant and fuel to reach the membrane electrode assembly (MEA). CFD-based simulation tools can be effective in designing and optimization of flow field plates as they cab fully account for the complexity and coupling of various transport phenomena as well as the 3-D geometry. The objective of this paper is to report on the development of such a simulation platform and on its application to investigate the impact of several geometric parameters on fuel cell performance and detailed distribution of transport processes. The simulation tool is built upon a commercial computational fluid dynamics (CFD) code, CFD-ACE+, along with supporting software and script codes to automate the design workflow. A 3-D, straight channel model with material properties and model parameters validated with experimental data is used as the baseline for the present study. The workflow includes automated grid generation, model setup and job execution. Parametric study is performed for geometric parameters including (1) Channel width versus land area width (2) Channel height (3) Channel pitch and length, as well as material parameters including (4) Porosity and (5) Electrical conductivity of the gas diffusion layer (GDL). Among these parameters, it is found that predicted cell performance is most sensitive to the channel/land width ratio and to the anisotropy of the GDL property. When isotropic properties are used for the GDL, the predicted cell performance decreases with increasing channel/land width ratio. This is because the current distribution in the MEA is dictated by electrical conduction through the GDL and increasing channel width causes current to peak underneath the land area, which in turn increases ohmic losses. When the in-plane electrical conductivity is reduced, the effect of mass transfer on the current distribution becomes comparable to electron transfer and the predicted trend line of cell performance shows an optimum value as a function of the channel/land width ratio. The CFD based design tool developed in the present work has the advantage of providing more reliable prediction than methods based on reduced dimensionality or simplified transport models.

"Advance Injection Strategy Optimization: Maximize Benefit-Cost Ratio by Integration of Economic Spreadsheet in Excel to Assisted History Matching Using Python Scripting."

Full textAbstract:
Abstract Oil prices see large fluctuations peculiarly over the last eight years due to natural disasters, political instability, and Covid-19 pandemic shock. These prompt to anxiety towards expenditure in planning and forecasting of a field development plan (FDP). Economic optimization of a reservoir under water drive can be extremely tedious and time consuming especially for complex field. Traditionally, upon completion of forecast optimization on fluid production, reservoir engineer willhand over the reservoir models to petroleum economist for economical evaluation. If the chosen development strategy is not economically viable, the model strategies will have to be updated, and continue the repetition of financial evaluation all over again. Hence, this paper established an automated workflow that diminished the dilemma on iterations obligation between simulation runs and financial reviews in searching for most efficient waterflooding strategy. The automated workflow is accomplished by bridging three tools together seamlessly utilizing python scripting. These include the cash flow economic spreadsheet model, the dynamic simulator, and an assisted uncertainty analysis tool. The process first started with defining the economic parameters such as OPEX, CAPEX, oil price, taxes, discounted rates, and other financial parameters on an annual basis in spreadsheet. The uncertainty parameters: water injection rate, maximum water cut, and injection duration will be evaluated during forecast optimization to produce project efficiency indexes: Net Present Value (NPV) and Benefit-Cost Ratio (BCR). This integration was achieved by python script that automatically creates a coding path which exchanges simulation production and economic spreadsheet data at every simulation time step and each development strategy, that require no manual intervention. The integrated economic-dynamic model workflow has successfully applied on West Malaysian field and Olympus model, a development strategy that maximize oil recovery without neglecting cost of water disposal, storage for total water produced from the reservoir. This paper successfully identified the most efficient waterflooding strategy and production constraints for each well using BCR as objective function for optimization. The optimum development scenario does have a BCR which is more than 2 which show that investment on that particular development strategy is profitable. The results also demonstrated a crucial impression that the highest oil cumulative production may not results in high BCR due to cost involvement in resolving water production and field maintenance services. This paper outlined the methodology, python scripting codes, and how integration automation works that successfully optimized an injection strategy in a development project using economic model from third-party application. The results of this automated workflow demonstrate a successful utilization of new technologies and simple customize programming knowledge that promote cross-discipline integration for enhanced work-time efficiencies in problem solving that is suitable for all reservoir model type to determine its success rate and economic viability during FDP.

Full textAbstract:
Abstract After successful implementation of data analytics for steamflood optimization at the Mukhaizna heavy oil field in Oman late 2018, Occidental expanded the project to two additional areas with a total of 626 wells in 2019, followed by full field coverage of more than 3,200 wells in 2020. In 2019, two separate low-fidelity proxy models were built to model the two pilot areas. The models were updated with more features to account for additional reservoir phenomena and a larger scope. On the proxy engine side, speed and robustness were improved, resulting in reduced CPU processing time and lower cost. Because of advancements in software programing and the pilots’ encouraging production performance, full-field coverage was accelerated so the model could support the efforts in optimizing steam injection during the 2020 OPEC+ production cut, not only to comply with allotted quotas, but also to allocate the resources optimally, especially the costly steam. Good improvements have been observed in overall steamflood performance, the models’ capabilities, and the optimization workflow. The steam/oil ratio has been reduced through the increase in oil production in both expanded study areas while keeping the total steam injection volume constant. Overall field steam utilization was improved both during the 2020 OPEC+ production cuts and during the production ramp-up stage afterward. With the continuous improvement in supporting tools and scripts, most of the steam optimization process steps were automated, from preparing, checking, and formatting input data to analyzing, validating, and visualizing the model outputs. Another result of these improvements was the development of a user-friendly web application to manage the model workflow efficiently. This web app greatly improved the process of case submittals, including data preparation and QC, running models (history matching and forecasting), as well as visualization of the entire workflow. In terms of optimization workflow, these improvements resulted in less time spent by the field optimization engineer in updating, refreshing, and generating new model recommendations. It also helped reduce the time spent by the reservoir management team (RMT) to test and validate the new ideas before field implementation. This paper will describe the improvements in the proxy model and the overall optimization process, show the observed oil production increases, and discuss the challenges faced and the lessons learned.
