Abstract:
The work of French ethnologist and prehistorian André Leroi-Gourhan (1911–86) represents an important episode in twentieth-century intellectual history. This essay follows the development of Leroi-Gourhan's relationship to the discipline of ethnology from his early work on Arctic Circle cultures to his post-war texts on the place of ethnology in the human sciences. It shows how in the pre-war period there is already a conscious attempt to articulate a more comprehensive form of ethnology including the facts of natural environment and material culture. The essay also indicates the biographical importance of Leroi-Gourhan's mission to Japan as a decisive and formative experience of ethnographic fieldwork, combining the learning of a language with extended immersion in a distinctive material and mental culture. Finally, it explores how in the post-war period Leroi-Gourhan's more explicit meta-commentaries on the scope of ethnology argue for an extension of the discipline's more traditional domains of study to include the relatively neglected areas of language, technology and aesthetics.

Abstract:
Updating Romanian Ethnology: traditions, themes, scientific practices Romanian Ethnology (named, at first, either Romanic Philology or Ethnopsychology) became an academic discipline at the end of the ninenteenth century, as part of Philology studies and in tune with European theories regarding comparative researches on folk (peasant) cultures as a means to identify origins, interrelations and evolution of peoples. As part of European Ethnology, Romanian Ethnology has evolved as a science engaged in the project of national construction and practising the discipline has always implied resisting political bias, especially during the communist period. After 1989, Romanian ethnologists have freely explored the limits of their science, criticising tradition and practising interdisciplinary approaches that have induced a fruitful state of internal crisis, out of which a „new Ethnology” has emerged. Although rural tradition and national and multiethnic cultural heritage remain the most important topics of Romanian Ethnology, there are also a series of recent themes (work migration, exploring socialism and postsocialism, urban cultures and many others) that integrate research into international trends. As far as specific practices are concerned, Romanian Ethnology (or its most „fashionable“ equivalent, Sociocultural Anthropology, as I demonstrate there is no substantial difference between ’Ethnology’ and ’Anthropologies’) is grounded in the research field which is explored by using qualitative methods.

Abstract This paper discusses Alfred Russel Wallace’s Amazonian ethnography and his collaboration with Robert Latham on the models of indigenous Amazonian peoples that were placed on display at the Crystal Palace ethnological exhibition in 1854. The reception of scholars and the public to this innovative work is also considered. Wallace’s involvement in the first British ethnological exhibition of large proportions was fundamental to the dissemination of his work, which made a valuable contribution to a field of study—the ethnology of South America—that was still in its infancy in Britain, in marked contrast to Portugal, Spain, Germany and France. Wallace’s field observations of indigenous peoples were instilled in the British imagination through the handbook to the exhibition, in which Latham stressed the importance of Wallace’s descriptions to the advancement of the field of ethnology. Indeed, Wallace’s ethnographic accounts were deemed to provide an authoritative supplement to James Prichard’s preliminary and still somewhat limited ethnological map of northern South America, contributing to the creation of a more complete picture of the indigenous Amazonian peoples of Brazil.

These are brief memoirs dedicated to the 80th anniversary of the Department of Ethnography / Ethnology, Faculty of History, Lomonosov Moscow State University. The author’s personal impressions date back to 1968-1974, when a whole galaxy of talented ethnographers worked under the leadership of the outstanding scientist S. A. Tokarev. They trained a large number of specialists who mastered the basics of scientific work, field research methods and continued the work of their wonderful teachers in various parts of the country. This testifies to the continuity of traditions in the field of ethnologica science and its relevance up to the present.

Abstract:
When in the 1880s and 1890s German Lutheran missionaries were sent to Australia from their colleges in Hermannsburg in Lower Saxony and Neuendettelsau in Bavaria to work among the Australian indigenous peoples of the Northern Territory, they had no ethnological education to speak of. This was particularly true for Carl Strehlow who, born in 1871 and educated from 1888 to 1891 at the Lutheran Missionary College in Neuendettelsau, arrived in Adelaide in 1892 and went straight to work with Pastor Reuther among the Diari in Killalpaninna, south of Lake Eyre. From there, in 1894, he was sent to Hermannsburg to resurrect the abandoned Lutheran Mission Station of the Finke River Mission, owned by the South Australian Immanuel Synod. The records of the curriculum in Neuendettelsau show no subjects teaching the theory and practice of ethnology. However, his ethnographic work among the local tribes of the Arrernte and Loritja is today still considered a classic in the field. As a contribution to the history of research methodology in the field of ethnology, I intend to give a brief outline of 1) the early development of scientific research instructions in general, and 2) as a special case, Carl Strehlow’s learning process in form of letters with questions and answers between himself in Hermannsburg and his editors in Frankfurt.

Abstract:
The authors give an overview of the academic career of Professor L.P. Lashuk. He was one of the leading professors of the Department of Ethnography (now Ethnology) of Moscow State University in the 1960-1980-ies. L.P. Lashuk received his degree at the Department in 1950, having obtained high-quality training. This enabled him to work successfully and fruitfully until 1960 in Syktyvkar, at the Komi branch of the USSR Academy of Sciences. He obtained national recognition for contributing greatly to the development of ethnography of the peoples of the Komi Republic. Having returned to Moscow to work at the History Faculty of the Moscow State University, the scholar used his rich experience in the field, expanded his research interests, became one of the Russian leading ethnologists, founded his scientific school. The authors believe that the Department of Ethnology played a tremendous role in the formation of LP. Lashuk as a professional, one of the most prominent representatives of national science among "second generation" professors of the Department of Ethnography.

Full text
Abstract:
The concept of social trust is located at the intersection of a broad field of meaning, including various theoretical tools in the social sciences: social capital, social networks, political power. It cannot be said that ethnology in Bulgaria has never studied socio-cultural phenomena in this light. Certainly, however, the work of Ana Luleva is the first systematic, competent, consistent and comprehensive study of the issue. In this sense, the book Culture of (dis) trust in Bulgaria: Anthropological Perspectives is not just innovative or makes a contribution. Undoubtedly it is, but more importantly, we have before us a serious and, I would say, a staged theoretical contribution in the field of social trust research. In itself, even just the introductory part of the work represents a serious theoretical effort.

Abstract:
All scholarly fields feed on rhetoric of praise and criticism, mostly self-praise and self-criticism. Ethnology and folklore studies are not exceptions in this, regardless of whether they constitute a single field or two separate but related ones. This essay discusses questions concerning ethnological practice and object formation, cultural theory and the theory of tradition (or the lack thereof), cultural transmission, cultural representation, and the ethics and politics of cultural ownership and repatriation. It draws on general observations as well as on work in progress. The main concern is with a discursive move: from tradition to heritage, from the ethnography of repetition and replication to cultural relativist descriptions and prescriptions of identity construction and cultural policy, from ethnography as explanation to ethnography as representation and presentation. In addition, the essay seeks to delineate other underlying tenets that appear to constitute our traditions and heritages - both as strengths and as long-term constraints and biases. Where is ethnology headed in its quest to transcend theories and practices? Less theory and more practice? More theory on practice? Or more practice on theory?

Abstract:

The study takes its point of departure in the notions of life story, narrativity and context. It is based on extensive life story interviews with well-educated professionals in Poland – academics, teachers, managers, physicians, artists – during the period of transformation (or transition) from ”real socialism” to democracy and a market economy. The aim is to analyse the multilayered process of constructing a personal identity, as the narrators interweave stories about their lives with images of history and society. The central approach is narrative analysis, focusing on the interview interaction as well as the wider cultural, societal and political context in which the self-presentation takes place, and which it simultaneously creates. Concepts of cultural and paradigmatic narratives are combined with a gender perspective and selected terms from Pierre Bourdieus theory of practice. The narrators’ life experiences are shaped and evaluated in an implicit dialogue with cultural narratives of ideal biographies, professional careers, gender roles and family models in Poland during socialism and the transformation. In family background stories, the ancestors’ gendered biographies are depicted in relation to the underlying paradigm of the romantic-patriotic tradition. In childhood stories, the evaluation models used are psychological, social and based on political correctedness. The interviewees often shape their nostalgic, bitter and ambivalent memories against a background of the power relations between the family and the state, using nostalgia, dark rhetorics and a well-established genre of coping strategies during the socialism. In narratives about formal school-education during the socialist period, two paradigms are seen as highly incongruous: the intellectual-elitistic tradition and the socialistic citizen-schooling. Also stories of being a part of both formal and oppositional organisations and networks are told. In narratives about careers and working life, the pride in doing a good work is prevalent, but the narrators also depict complications in the professional paradigm due to the proliferation of politicised and informal power relations; en influence still lasting during the transformation period. The troubled issues of legitimacy, status and economy are discussed. In stories about close relationships, there is an underlying paradigm of love, marrital happiness and being a good parent, even though the stories follow a variety of plots. The evaluations become complex and sometimes contradictory. By presenting their life-experience in a proud, ambivalent, defensive or ironic way, the narrators reproduce, deconstruct and challenge the dominant cultural narratives, shaping their unique personal paradigms.

The chapter examines the physical, psychological, and emotional challenges faced by researcher and research participant in qualitative field research into the underlying drivers of violent communal conflict, as well as inhibitors to successful resolution. The reflections in this chapter are drawn from the author’s qualitative field research experiences in Somalia, Yemen, Darfur Sudan, Niger, Colombia, Iraq, and Afghanistan. The utility of this chapter is a deeper appreciation of the importance of qualitative field research in studies involving violent communal conflict, and an understanding of how transference and countertransference work to degrade data collection and analysis.

In recent years, environmental security in the coastal Niger Delta has had a growing scholarly interest from divergent perspectives seeking for broader elucidation and understanding of State policy response. These security threats notably oil spill, water and land pollution, gas flaring, acid rain, mangrove deforestation, etc are linked to the Multinational Oil Corporations (MNOCs)and oil resource exploitation. These have been perverse, resulting in ecological breakdown, vulnerability, emergency and environmental insecurity challenges since at least the 1970s when oil in the region became the main stay of Nigeria's economy. This conceptual paper builds on the political ecology framework which discusses the impact of global power asymmetry on natural resource extraction and extensive body of work in the broad field of environmental security to explore salient indicators which demonstrate the evidence of environmental insecurity threats and poor State policy response and made some recommendations.

Full text
Abstract:
Ernesto de Martino (1908–65) could be described as one of the founding figures of Italian ethnology. Until his work was translated into English, he was fairly unknown to English-speaking anthropologists. Since then, however, the importance of his contributions to the field has received wider recognition. In the book Terra del Rimorso: Contributo a una storia religiosa del Sud (The Land of Remorse: A Study of Southern Italian Tarantism), de Martino unravels how alterity may be found “at home,” through a study in the southern peninsula of Salento of rural people seasonally affected by tarantismo, a form of possession attributed to the bite of the tarantola spider.1 The affliction is cured by the performance of “choreutic” dances followed by pilgrimages and offerings made to Saint Paul. For de Martino, tarantismo is the living presence of an other-than-Catholic history—an echo of earlier pagan, erotic ritual forms. Tarantism can be understood only when placed within the context of Catholicism’s regional history, its broader social and economic conflicts, and tensions around gender, kinship, and sexuality within the home. The cult is one that the Catholic Church has “purged” but also resignified and appropriated in an effort to contain its vitality. As de Martino shows, however, the church’s engagement with the cult in the first half of the twentieth century colludes with scientific and medical—particularly psychiatric—discourses. The relevance of this work for a modern anthropology of Catholicism is plain in its historical breadth and the richness and detail of de Martino’s ethnographic research. But it is also interesting for the way it highlights how questions of science, magic, and enchantment have posed challenges of different types for the modernizing, bureaucratic church.

Full text
Abstract:
Abstract The development plan of the new oil field discovered in a remote offshore environment, Niger Delta, Nigeria was evaluated. As the oil in place is uncertain, a probabilistic approach was used to estimate the STOOIP using the low, mid, and high cases. The STOOIP for these cases were 95 MMSTB, 145 MMSTB and 300 MMSTB which are the potential amount of oil in the reservoir. Rock and fluid properties were determined using PVT sample and then matched to the Standing correlations with an RMS of 4.93%. The performance of the different well models were analyzed, and sensitivities were run to provide detailed information to reduce the uncertainties of the parameters. Furthermore, production forecast was done for the field for the different STOOIP using the predicted number of producer and injector wells. The timing of the wells was accurately allocated to provide information for the drillers to work on the wells. From the production forecast, the different STOOIP cases had a water cut ranging from 68-73% at the end of the 15-year field life. The recoverable oil estimate was accounted for 33.25 MMSTB for 95 MMSTB (low), 55.1 MMSTB for 145 MMSTB (mid) and 135 MMSTB for 300 MMSTB (high) at 35%, 38% and 45% recovery factor. Based on the proposed development plan, the base model is recommended for further implementation as the recovery factor is 38% with an estimate of 55.1 MMSTB. The platform will have 6 producers and 2 injectors. The quantity of oil produced is estimated at 15000 stbo/day which will require a separator that has the capacity of hold a liquid rate of about 20000 stb/day. The developmental wells are subsequently increased to achieve a water cut of 90-95% with more recoverable oil within the 15-year field life. This developmental plan is also cost effective as drilling more wells means more capital expenditure.

Full text
Abstract:
Abstract Geologic model updates especially when driven by seismic data generally help for better field understanding, and in most cases, aid the targeting of nearby undeveloped prospects or infill opportunities and robust geosteering of infill wells for efficient drainage or sweep and well recovery optimization which help to prolong field life and maximize the returns on investment of mature fields. The Akpo V & W reservoirs case study lie in the central part of the mature Akpo field. They are characterized by laterally offset stacked turbidite channels with dense network of faults. This work illustrates the collaborative team effort performed through the integration of geoscience and reservoir engineering data in constructing the static model of the V & W reservoirs. This new model aims to address the uncertainties and limitations of the previous model, re-evaluate the volumes in place, better represent the dynamic behavior of the reservoirs to aid history match, forecast and optimize infill well placements within undrained areas to sustain production. This will in turn, improve the recovery factor and the management of the reservoirs. The new model incorporates new petrophysical synthesis for all development wells, re-interpreted faults, horizons and AEs on a new seismic dataset (2018 4D M3 B98), Lithofacies trends from seismic reservoir characterization study, amongst others. Structural and property modelling results with QCs shows better respect of well, seismic data/trends and facies heterogeneities; giving rise to a more robust model that meets the specified objectives.

Abstract:
Abstract Enhanced oil recovery has been gaining relevance over the years following success stories from already executed projects from various parts of the globe. The recoveries from such successful projects have tremendously increased the terminal life cycle recoveries from the subject reservoirs and subsequently the project Net Present Value and Value to Investment Ratio. More than 90% of Field Development Plans in the Niger Delta have not considered Enhanced Recovery Mechanism as part of the field development options and as such Top Quartile Recovery Factors are never achieved. In this study, the effectiveness of Enhanced Oil Recovery within the Niger-Delta reservoir sands via 3-Dimentional Dynamic Simulation, Economic models and Experimental investigations (temperature and pressure effects on polymer effectiveness) was done. The GN7000 reservoir was used as a case study for this work. This reservoir is the largest gas cap reservoir in the N-Onshore field within the Niger Delta area and it is at the mid-life stage. This study tested the effectiveness of three Recovery mechanisms (Water Flood, Polymer Flood and Polymer Alternating Gas). Simulated and Experimental result suggests that Polymer flooding and Polymer Alternating Gas (PAG) yields greater Technical Ultimate Recovery, better economic indices but greater complexity in polymer selection due to inherent high reservoir temperature and low salinity that make the use of synthetic polymers inadequate. Experimental investigation showed that biopolymers are most suitable for this sand. The suitability of some biopolymers (Xanthan and copolymers containing high level of 2-acrylamido2-methyl propane sulfonate (AMPS) showed good results. Study results shows that with the deployment of biopolymers with high viscosifying power and high resistance to thermal degradation an incremental recovery of 8% from the natural flow could be achieved. Research findings indicate that biopolymers could yield good results for Niger Delta sands within the pressure and temperature ranges of 93°C and 290 Bar.

Abstract:
Abstract Underground storage of carbon dioxide (CO2) has been recognized as a viable strategy to reduce CO2 emissions in the atmosphere. In this context, numerical reservoir simulations are routinely implemented to predict the performance of the project under different operational scenarios and uncertainties. However, numerical simulators are intensive in terms of cost, computational time, and data requirement, thus limiting its use for early commercial applications especially for feasibility studies or quick evaluations. This paper presents the application of a simplified modelling approach to predict dimensionless pressure build-up and injectivity index based on an analytical model for reservoirs in Niger Delta. Data from four (4) Niger Delta reservoirs such as relative permeabilities, reservoir pressure, brine viscosity, and injection rate, among others were used in this work. A modified version of the physics-based model of Mishra et. al was used for conducting the studies. Therefore, equations governing the dimensionless pressure build-up and injectivity index were used to investigate the reservoir and operational characteristics of the well injection of CO2 in Niger delta reservoirs as an alternative to full-field numerical simulation. The model approximates the CO2 injection rate for a given target pressure differential or alternatively, the pressure differential that would result from injecting CO2 at a target rate, given the initial permeability, porosity, permeability, and injection rate. The results were used to rank the reservoirs based on suitability to CO2 sequestration, the displacement efficiency of the CO2 and potential storage in the reservoir. This approach is the first one carried out in the Niger Delta and provides the chance to assess the performance of CO2 storage capacity as a strategy to combat global warming from Nigeria.

Abstract:
Abstract An evaluation of potential EOR processes applicable in the marginal oil field operation of the Niger Delta region is presented. Technical feasibility, process availability, oil recovery potential, and other uncertainties and risks associated with exploitation of enhanced oil recovery technique in a marginal oil field environment are being assessed. Few Enhanced oil recovery processes, namely polymer flooding, chemical flooding and microbial EOR (MEOR), are considered for possible application in this marginal oil field. The objective of the screening study is to evaluate and rank the EOR options and also select the most attractive method that will have to be further chased to a pilot test stage. Emphasis is strictly on a technical assessment of the incremental oil potential of each of the EOR methods and also identification of critical operational and logistical components of the entire process for their implementation in the offshore operating environment. Recoverable volumes associated with EOR may be significant, but key project development and implementation challenges and extra cost elements must be considered in any EOR forecast for an effective EOR process ranking. Some of these concerns (e.g. Polymer/chemical supply, facilities requirements, and the impact of EOR on reservoir performance and wellbore integrity) may be significant enough to eliminate a method from being considered further and at that point the best EOR option that requires minimal cost exposure for achieving the best recoverable shall be considered. Moreso, there is consideration of the quantity and quality of laboratory data that should support the viability of each EOR process being considered. This paper narrates the state of technical readiness for field implementation of each EOR method and identifies remaining work required to progress EOR process in this marginal oil field.

Abstract:
Abstract Erosion is a major issue that could be encountered in the oil and gas production and transportation facilities. Oil and gas companies have always tried to develop proper methods to limit erosion to an acceptable level. For many years now, many oil and gas field operators have adopted the America Petroleum Institute recommended practice 14E (API RP 14E) equation to estimate the erosional velocity. Unfortunately, the C-factors in the API RP 14E equation has been generalized, even to conditions and applications where it was invalid, resulting to varying degree of success. In this work, thousands of well performance simulations were carried out to generate stable operating production rates using data from vertical wells in oil rim reservoirs in the Niger Delta. Approximate model was then developed for erosional velocity calculation using the least square regression method. Furthermore, the developed model was compared with other existing erosional velocity correlations. The new model can be helpful for the design of production facilities for oil rim reservoirs.

"Harnessing Value from Mature Offshore Asset: Successes from Recent Acid Stimulation Campaigns in Field X." In SPE Nigeria Annual International Conference and Exhibition. SPE, 2023. http://dx.doi.org/10.2118/217189-ms.

Full text
Abstract:
Abstract Field X is a mature offshore field in the Niger Delta. In 2013, several wells in field X experienced significant production decline and a study conducted by cross-functional team identified fines migration as the primary cause of sandface impairment and acid stimulation was recommended as remediation for the damage. This technical work highlights the strategies and methodology adopted in implementing acid stimulation in field X. The approach to candidate selection involved screening of historical well test data and pressure transient analyses (PTA) database for impaired/at-risk completions. Typical selection criteria are productivity index (PI) degradation (> 50%), pressure drop due to near wellbore skin (DP skin >500psi), violation of flux constraint, Interval Control Valve (ICV) integrity (dual completion) and water-cut evolution (<5.0%). The team also piloted diversion agents in the field to improve stimulation in wells with high water-cut. A novel method of using dynamic positioning marine vessel with Remotely Operated Vehicle (ROV) and customized dual conduit Coil Tubing (CT) have been deployed to bullhead acid into the formation. In the last two campaigns executed in 2020 & 2021, this ingenious way of harnessing value from field X has resulted to combined incremental Initial Production (IP) gain of approximately 10,000 bopd and safeguarded completion of a critical oil producer (~11,000 bopd). The total project cost for the two campaigns was ~$25.4 million resulting in significant cost savings (>$51.6 million) compared to rig operations. The use of cross-functional team, robust candidate selection, continuous lookback and adoption of best practices were critical to successful execution. Some challenges being experienced in the field are lack of adequate injectivity, formation lock-up, increasing gas oil ratio (GOR) and increasing water-cut. The team plans to deploy diverters across additional high water-cut wells in future campaigns.

Abstract:
Abstract A detailed geological model was built to form the basis for a Near Field Exploration (NFE) project required to secure gas supply shortfall in an area ("cluster") onshore Niger Delta. The key business driver is the proximity (~2-10km) of leads and prospects in the cluster to an existing gas plant in the area. Proximity to the gas plant is expected to facilitate early production hook-up and enhance the Net Present Value of the projects. Moreover, robust exploration success potentially provides lower Unit Development Cost (UDC) options. The methodology involved seismo-sequence stratigraphic analysis using data from 19 wells penetrating Tortonian 1, Serravallian 2 and Langhian 1 maximum flooding surfaces (MFS). The geological model integrated distinct seismo-sequence stratigraphic analysis, regional isopach maps, sand supply/distribution trend analysis, seismic attribute extractions and geo-feature highlighting volumes. The combination of the seismic velocity data and geological model show consistent velocity reversals in the outer shelf to shelf margin Gross Depositional Environment in a distinct relationship with the interval net-to-gross (NTG). Drilling kicks occurred in outer shelf to shelf margin sediments with relatively low interval NTG (~15-60%). This work significantly contributes to the understanding of the prospectivity and associated subsurface risks in the cluster area. It has influenced the polarization of the exploration portfolio into low risk, medium to high NTG conventional opportunities and high risk, medium to low NTG deep high-pressure (HP) opportunities. It is the bedrock of the formation pressure prediction in the cluster area.

Abstract:
As the need to ensure thermal comfort in buildings is constantly evolving, new technologies continue to emerge with the aim to develop efficient thermal insulation materials. This study aims to explore a textile technology using Airlaid process to develop non-woven fabrics made of natural fibers extracted from Posidonia Oceanica’s waste for assessing their suitability for insulation products in construction field. This technology offers the feature to develop isotropic non-woven structures by orienting randomly the fibers on the fabric surface. The web composed of a mixture of Posidonia Oceanica fibers and a proportion of thermoplastic fibers is then thermally bonded in an oven followed by cooling in order to ensure the solidification of the bonding areas. The prepared panels are then analyzed for the thermal conductivity. It was found that their thermal conductivity is close to commonly used thermal insulation materials, ranging between 0.03515 W/m.K and 0.03957 W/m.K, which allows the non-woven panels to compete with widely-used insulation materials for building’s field. The second part of this work aims to determinate the Posidonia panel's resistance to five common mold types in buildings (Aspergillus niger, Penicilumfuniculosum, Trichoderma viride, Chaetomium globosum, Paecilomycesvariotii). In fact, at high moisture content, molds are likely to develop on cellulosic materials affecting indoor air quality and eventually causing a variety of health risks to occupants. However, optic microscope results showed no growth of molds on the Posidonia samples which allows conceiving reliable thermal insulation materials.

Abstract:
Abstract Oil field Operations such as wellbore stability Management and variety of other activities in the upstream petroleum industry require geo-mechanical models for their analysis. Sometimes, the required subsurface measurements used to estimate rock parameters for building such models are unavailable. On this premise, past studies have offered variety of methods and investigative techniques such as empirical correlations, statistical analysis and numerical models to generate these data from available information. However, the complexity of the relationships that exists between the natural occurring variables make the aforementioned techniques limited. This work involves the application of Artificial Neural Networks (ANNs) to generating rock properties. A three-layer back-propagation neural network model was applied predicting pseudo-sonic data using conventional wireline log data as input. Four well data from a Niger-Delta field were used in this study, one for training, one for validating and the two others for generating and testing results. The network was trained with different sets of initial random weights and biases using various learning algorithms. Root mean square error (RMSE) and correlation coefficient (CC) were used as key performance indicators. This Neural-Network-Generated-Sonic-log was compared with those generated with existing correlations and statistical analysis. The results showed that the most influential input vectors with various configurations for predicting sonic log were Depth-Resistivity-Gamma ray-Density (with correlating coefficient between 0.7 and 0.9). The generated sonic was subsequently used to compute for other elastic properties needed to build mechanical earth model for evaluating the strength properties of drilled formations, hence optimise drilling performance. The models are useful in Minimizing well cost, as well as reducing Non Productive Time (NPT) caused by wellbore instability. This technique is particularly useful for mature fields, especially in situations where obtaining this well logs are usually not practicable.

Abstract:
Fruit thinning is a common and necessary practice for commercial fruit production in many deciduous tree fruit species. Fruit thinning in apple may be accomplished with a variety of chemical thinning agents, but the use of these chemicals is a subject of environmental concern. It has been shown recently that RNase enzyme, secreted from the stigma and the style, inhibits pollen germination and pollen tube elongation. In this study we have been able to show that Aspergillus niger B-1 RNase can effectively inhibit peach and apple pollen germination, and tube elongation in-vitro, as well as thin fruit in peach and apple, and reduce the number of seeds in citrus. The objectives of the research were to detrmine the conditions for effective thinning of (USA and Israel), develop fermentation process for cost effective production of RNase from A. niger. (Israel), and clone apple S-RNase cDNA (USA). All the objectives of the research were addressed. We have determined the optimal fermentation conditions for cost effective production of the A. niger at a 20,000 liters scale. TheA. niger B1 RNase was isolated to homogeneity and its kinetic and biochemical properties including its N-terminal sequence were fully characterized. The field test results both in Israel and California have shown variability in effectiveness and more work is needed to define the RNase concentration necessary to completely inhibit pollen development. Plant transformation vectors expressing anti-sense apple S-RNase genes were constructed (USA) with an attempt to produce self compatible transgenic apple trees. Bovine S-Protein cDNA was cloned and successfully expressed in E. coli (Israel). Plant transformation vector expressing the S-Protein gene was constructed (USA) with an attempt to produce transgenic plants expressing S-protein in the style. Exogenous application of S-peptide to these plants will result in active RNase and consequently prevention of fertilization.
