Rural Sociology and ‘Rural’ Linguistics. The Biographical Method in the Study of Dialects and Languages in Contact
Authors: Głuszkowski Michał
Published: April 2019

In the year 2018, marking the anniversary of their original releases, the main of the article is to discuss the question concerning the applicability of The Polish Peasant in Europe and America (1918) by William Isaac Thomas and Florian Znaniecki and Młode pokolenie chłopów [The Young Generation of Peasants] (1938) by Józef Chałasiński, two crucial works in rural and general sociology to other areas of humanistic disciplines, with examples drawn from linguistic research. Here, we both characterise and justify the historical and contemporary relationships between sociology and linguistics both on a general level and in their rural varieties. Cooperation between representatives of the given disciplines is possible on the ground of structuralism and, in fact, is being implemented in many joint research projects.

Rural sociology has established itself as a subdiscipline of sociology and has developed its specific thematic and methodological autonomy within the major scope of the field. The existence of ‘rural’ linguistics is not so obvious, but there are certain phenomena and processes observed in rural conditions which justify the use of such a term. However, it is not the officially accepted name of the subdiscipline which, in the present article, is defined as ‘linguistic (and sociolinguistic) research in rural area’ with constant references to dialectology.

Hence, methods such as the personal documents method and the biographical method are already present in linguistics and sociolinguistics, although direct references to sociological works (both in general and specifically to both Thomas and Znaniecki’s and Chałasiński’s texts in detail) are rare. Still, some popular linguistic approaches – e.g. language biographies or the use of personal documents as a source of linguistic data – are very close to the ideas postulated by the precursors of rural sociology. There are also authors who have so far used Thomas and Znaniecki’s as well as Chałasiński’s theoretical achievements, while they refer consciously and directly to The Polish Peasant in Europe and America and The Young Generation of Peasants.

Published: April 2019

The purpose of this paper is to determine the family situation and family preferences in rural parts of the Ukraine. This study investigates social integration of people in various types of municipalities and size characteristics of families. The results were compared with Ukrainian urban families and Czech rural and urban families. Besides the statistical data, results of a questionnaire survey were organised by means of social networks were used. The results suggested that relations between people and their community life and their social integration are influenced by the cultural context, historical aspects and the economic level. The differences between the contemporary Czech and Ukrainian rural families can be observed in different pathways and in a different part of the job market.
The Proportion of Binge Drinking Among Female Social Drinkers of Kalingalinga in Lusaka, Zambia: A Pilot Study
Authors: Likashi Danny Vumbi , Paul Ravi , Jason Luty
Published: April 2019

Objectives

Alcohol is a psychoactive substance with dependence-producing properties. Alcohol’s harmful use causes large burden diseases like social and economic burden in societies. Binge drinking is one of the commonest forms of alcohol misuse and has been on an increase among many young women, who find alcohol a source of pleasure and enjoyment when they have timeout with friends and peers. Since binge drinking involves consumption of alcohol on an irregular basis, it may not be viewed as a hazardous form of alcohol use by many drinkers. The present study is aimed at estimating the proportion of female binge drinkers in the population of female social drinkers in Kalingalinga township of Lusaka, the capital city of Zambia. We hypothesised that the proportion of binge drinking in the population of female social drinkers is significantly high.

Methods

Through snowball sampling, 100 questionnaires (i.e., Alcohol Use Disorders Identification Test-AUDIT) were successfully distributed to and collected from the female social drinkers aged 20–39 years between August and September, 2016. A two-fold process was followed in identifying the binge drinkers; screening for hazardous alcohol drinkers by identifying those that scored 8 points or above in the first place, and thereafter, identifying binge drinking characteristics from the hazardous drinkers by following scores from the first three questions on the AUDIT.

Results

The results reviewed that 54 of the 100 participants had some form of hazardous alcohol use and 30 of the 54 hazardous drinkers possessed some binge drinking characteristics. The proportion of female binge drinkers in a population of female alcohol drinkers was estimated to be 0.556 (56.6%), while in the general population, it was estimated to be 0.094. This implies that 9.4% of women aged 20–39 years of Kalingalinga in Lusaka engage in alcohol binge drinking, consuming on average 7–9 drinks on occasion almost on a weekly basis. Further, if 56% of all female alcohol drinkers aged 20–39 years seem to engage in some form of alcohol binge drinking, it means that that binge drinking is the highest form of alcohol misuse among these female drinkers.

Conclusion

The results of the present study suggest that there is more alcohol binge drinking among the female social drinkers of Kalingalinga in Lusaka, with an estimated proportion of 0.556 (55.6%) among the female alcohol drinkers and 0.094 (9.4%) in the general population of females aged between 20–39 years. The implication is that alcohol binge drinking seems to be the highest form of alcohol misuse among female drinkers in Kalingalinga.

NATO reqiurements as referred to risk in executed contracts
Authors: Wójcik Joanna , Kosiński Włodzimierz
Published: April 2019

Requirements on risk management are a problem that is described in all of NATO documents written for contract execution purposes. Namely, these documents have become the basis to introduce these requirements into other documents that apply to various aspects of life.

This article describes problems concerning a risk-based approach in executing contracts for the military.

The core of the documents, developed by the NATO members, has been, since the foundation of these documents, the ISO 9001 standard. Although in the history of the NATO document’s period of validity, they had structure identical to the one of ISO 9000 standard series, in their last iteration they gained their specific structure of contents, oriented for specification of the requirements for contracts execution.

Authors: Leśniczak Andrzej , Gębura Andrzej
Published: April 2019

This article comprehensively addresses the problems associated with the structure of recurrent circuits of military aircraft with metal fuselage structure. The authors describe the issues concerning the usage of the fuselage as a recurrent circuit of electric current and with negative conductors connecting the fuselage with negative terminals of the receiver or the source. The military aircraft are frequently operated under harsh conditions of increased humidity, dustiness and variable temperatures. All these factors as mentioned above contribute to the occurrence of intensive electrochemical corrosion at the contact points of airframe’s elements or electrical conductors’ with the fuselage. Such contact surfaces should be subject to monitoring – AFIT has developed the numerous procedures for each aircraft.

Olympic Games Rio 2016: The Legacy for Coaches
Authors: Padrão dos Santos Ana Lúcia
Published: April 2019

The purpose of this study is to identify the legacy of the Olympic Games for sports coaches with a special focus on professional education. Thus, in framing this study, two research questions are posed: 1) How did Olympic Games affect the characteristics of the educational activities for coaches? 2) What was the perception about the coaches' education in Brazil, and the legacy of the event for coach's education and career? The methodology used was the content analysis of the websites of National Sports Confederations, Institutions of Higher Education in the State of Rio de Janeiro, and the National and Regional Professional Councils in Brazil, totaling 70 institutions. Concomitantly, interviews were conducted with members of the Ministry of Sport, the Brazilian Olympic Academy, and the Federal Council of Physical Education. The interview questions were grounded on the theoretical framework of Sports Policy Factors Leading To International Sporting Success - SPLISS, which included: 1) the existence of well-trained and experience elite coaches in the country; 2) opportunities to develop their coaching career to become a world-class elite coach; 3) the status of coaches and the recognition of their work as valuable throughout the country. The results indicated that the event brought few benefits to coaches. In addition, according to the interviews, coaches play a secondary role in the organization of the Olympic Games, although they are considered fundamental for the development of the sport. Based on the results, this study discusses the education of coaches and the perceived importance of coaches according to the sports and educational institutions.
The Transboundary Water Management – Comparing Policy Translations of the Water Framework Directive in the International Basin Districts of the Oder River and the Torne River
Authors: Ibragimow Aleksandra , Albrecht Eerika , Albrecht Moritz
Published: April 2019

The European Union’s Water Framework Directive introduced a new approach to the system of water management in Europe by nominating the river basin district as the basic unit in water management. While its transboundary character aims to better manage natural resources, its design and implementation carries several challenges due to its weak integration of various bordering effects related to administrative boundaries that strongly affect the directives’ implementation. Based on a comparative document based case study of two river basin districts – the International Oder River Basin District (IORBD) and the International Torne River Basin District (ITRBD) – the paper scrutinizes the effects on the implementation processes of the directive and aims to draw attention to identify the differences that derive from various socio-spatial settings during the first cycles of water management plans from 2009 to 2015. By thematically comparing biophysical characteristics, cross-border cooperation, cultural and administrative bordering processes the study displays a mismatch between the directives aims for transboundary governance and the actual governance processes which are hampered by a variety of conflicting bordering processes.
Challenges in Geography Education – A Review of Research Problems
Authors: Piotrowska Iwona , Cichoń Małgorzata , Abramowicz Dawid , Sypniewski Jakub
Published: April 2019

Scientific research and student education aimed at preparing students to practice their profession under the conditions of civilization and technological changes play a special role in geography teaching. It is important to be aware of the impact of key competences which are necessary for every person to function in the modern world and are needed for self-fulfilment, personal development, social integration, flexible adaptation to any changes and which determine the success in adult life. Proper development of such skills contributes to the correct interpretation of natural and socio-economic phenomena and processes. The aim of the article is to present and discuss research work and teaching activities pursued by the Department of Geography Didactics and Ecological Education at the Faculty of Geographical and Geological Sciences of the Adam Mickiewicz University in Poznań, aimed at the use by students of various educational concepts and the resulting key competences necessary for their future work. Students also have the opportunity to develop soft competences, such as communication, courage of expression, self-esteem or responsibility for the group, to which employers have paid special attention in recent years. Therefore, comprehensive preparation of the student requires the implementation of specific educational concepts. The most important ones include bilingual education; CLIL, inquiry based science education (IBSE), project method, fieldwork, geographical educational trails, participation, as well as the use of geoinformation technologies, GIS and ICT.
Socio-economic Development and its Impact on Health Personnel in Regions of Visegrad Group Plus Countries
Authors: Majerová Ingrid
Published: April 2019

The quality of life and economic development of economies and their regions is influenced by socio-economic indicators such as unemployment, healthcare and education, environmental issues or household equipment. The question remains whether these indicators within regions can also influence each other and whether they have positive or negative effects. The paper aims to describe the impact of the selected socioeconomic indicators on health personnel, which was also divided from the gender perspective. For this purpose, the regions of the Visegrad Group Plus countries at NUTS II level were selected. The research was performed in the period from 2004 to 2013. According to our results based on the Generalized Method of Moments with panel data, we found out that a change in household income and a change in the number of vehicles in the monitored regions have the greatest (positive) impact on staff in hospitals. The research may contribute to the discussion about levels of regional economic development and the related competitiveness in terms of the socio-economic approach, and it may also provide a basis for further discussion on its measurement and use of appropriate indicators.
The determinants of consumer behaviour of students from Brno when purchasing organic food
Authors: Švecová Jana , Odehnalová Pavla
Published: April 2019

The subject of this paper is the analysis of consumer behaviour in the organic market, focused on the behavior of students from Brno. Our study brings information which can potentially be used for further research and will also be useful for organizations with a practical interest in the production sale and distribution of organic food. To investigate the influence of the various factors was used the extended model of Theory of Planned Behaviour (TPB). In the current concept, there is no research in the Czech Republic that would apply the approach of Yadav and Pathak (2016) to examine of consumer behaviour on the sample of students, i.e. young Czech generations who are a potential target group. The theoretical part deals with the concept of consumer behaviour, based on the findings of the latest studies, dealing with this topic. In the practical part, the own research is presented, realized on a sample of 403 young consumers, studying in the second largest city of the Czech Republic, the city of Brno. In the Czech Republic, the young consumer is influenced mainly by factors such as personal attitude and subjective norms. Limitations of this study are the fact that in our questionnaire we were interested in how the consumer viewed the purchase of organic food in general and not how they view the purchase of individual organic products and that the research may be limited by the fact that the questionnaire was aimed solely at the younger generation of consumers studying in Brno, the second largest city in the Czech Republic. The behaviour of the younger generation has received little investigation, and in the Czech Republic, there is a lack of research on the behaviour of this sector.
SCHOOL SUBJECT «RUSSIAN LANGUAGE» IN THE MODERN SYSTEM OF LINGUISTIC EDUCATION
Authors: Zamaletdinov R. R. , Yusupova Z. F. , Zakiryanov K. Z.
Published: April 2019

Te article deals with the specifcs of teaching Russian as a native language in the Russian school and as a non-native language in non-Russian schools. Tis specifcity is determined by the fact that with the same content of the subject “Russian language”, the ways of mastering language units and the formation of speech skills in native and non-native speakers are diﬀerent. In this regard, the problems of motivational and informative character are considered. Te authors conclude that the assimilation of the second language is accompanied by the assimilation of a new linguistic picture of the world. Te interrelated study of language and culture ultimately contributes to the formation of a bilingual person capable of using the means of Russian and native languages, taking into account the specifcs of national cultures. Te necessity and expediency of the development of various methods of teaching Russian as a native and as a non-native language, as well as the need to create special textbooks of the Russian language for Russian and non-Russian schools are considered. Te authors are convinced that in modern conditions it is necessary to develop nationally oriented textbooks of the Russian language, taking into account the specifcs of the native language of students, especially because in some national republics work in this direction has been conducted for a long time.
The Rating Game: The Discipline of Uber’s User-Generated Ratings
Authors: Chan Ngai Keung
Published: April 2019

On-demand labor platforms are built around user-generated rating systems that entail consumers’ monitoring of workers as a tool for algorithmic labor management. The user-generated ratings can directly determine workers’ employability. Workers are thus under pressure to score well, though they may lack knowledge about the performance metrics. Using in-depth interviews with Uber drivers, this article examines how Uber’s rating system as an engine of anxiety shapes drivers’ work practices through processes of surveillance and normalization. Specifically, drivers are prompted to play the rating game, a game that pressures them toward the normalization of platform surveillance and self-discipline for maximizing their ratings. The internalization of ratings is channeled through drivers’ reactive practices in the rating game—that is, drivers’ modification of their behavior in response to being evaluated and monitored. This article considers the socio-technical conditions under which drivers are subject to the platform surveillance and disciplinary power.
The Platformization of the Classroom: Teachers as Surveillant Consumers
Authors: Kumar Priya C. , Vitak Jessica , Chetty Marshini , Clegg Tamara L.
Published: April 2019

Technology platforms, including learning management systems and monitoring tools, have taken root in schools. While seen as bringing efficiency or innovation into classrooms, they also offer greater capacities for surveillance. Drawing on findings from focus groups with teachers in the US, we explore how teachers’ use of technology platforms produces surveillance. We argue that this positions teachers as surveillant consumers who use monitoring as a way to fulfill their responsibilities to students. We portray two configurations of monitoring in the classroom: tracking student learning and keeping students on task. These configurations reveal how technology platforms orient teachers to see student data as interchangeable with students, which we believe highlights the need for greater scrutiny of technology platforms’ role in the classroom.
Deportation Platforms: The AWS-ICE Alliance and the Fallacy of Explicit Agendas
Authors: Fleury-Steiner Benjamin
Published: April 2019

In this paper, I analyze elite discourse in the context of the increasing role played by large-scale corporate platforms in federal immigration enforcement in the US Specifically, I focus on Amazon Web Services’ (AWS) alliance with Immigration and Customs Enforcement (ICE). Incorporating Marx’s (2016) “fallacy of explicit agendas” as a heuristic for contextualizing recent employee challenges to company CEO Jeff Bezos, I show how the fallacy serves to conceal far more about the AWS alliance with ICE, an organization with a long track record of deeply troubling practices. The secrecy that is fostered by such discourse also obscures the growing dependency of government entities on large-scale technologies of marginalizing surveillance that threaten civil liberties and rights of refugees and immigrants.
Watch Me Pay: Twitch and the Cultural Economy of Surveillance
Authors: Partin William Clyde
Published: April 2019

This paper describes where and how research into the Amazon-owned livestreaming platform Twitch can profitably engage surveillance studies. It argues that Twitch sits at the intersection of what David Lyon calls “surveillance culture,” a culture in which watching and being watched is fundamental to individuals’ customs, habits, and ways of interpreting the world; and surveillance capitalism, Shoshana Zuboff’s term for an emerging logic of accumulation built on data collection and hoarding. I draw attention to three different actors in the Twitch ecosystem—the viewer, the streamer, and the platform owner—to articulate the different modes of seeing and being seen each position affords. In all cases, I illustrate how visibility is bound up in a complex, multidirectional web of political economic relations. In order to resist technological determinist narratives about platform effects, I consider Twitch as a “boundary object” in order to identify how social, geographical, and cultural context influences actors in each position. I conclude by offering some observations about what Twitch reveals about platform surveillance in general.
Meshes of Surveillance, Prediction, and Infrastructure: On the Cultural and Commercial Consequences of Digital Platforms
Authors: Helles Rasmus , Flyverbom Mikkel
Published: April 2019

Digital platforms like Spotify, Netflix, and YouTube rely on mass data collection, algorithmic forms of prediction, and the development of closed digital systems. Seemingly technical and trivial, such operational and infrastructural features have both commercial and cultural consequences in need of attention. As with any other kinds of infrastructure, the surveillance practices and digital ecosystems that are now installed and solidified will have long-term effects and will be difficult to challenge. We suggest that the cultural and commercial ramifications of such datafied infrastructural developments can be unpacked by analyzing digital platforms—in this case Netflix—as surveillance-based, predictive infrastructures. Digital platforms fortify their market positions by transitioning surveillance-based assets of audience metrics into infrastructural and informational assets that set conditions for other actors and approaches at work in the domain of cultural production. We identify the central forces at play in these developments: digital platforms critically depend on proprietary surveillance data from large user bases and engage in data-structuring practices (Flyverbom and Murray 2018) that allow for predictive analytics to be a core component of their operations. Also, digital platforms engage in infrastructural development, such as Netflix’s decentralized system of video storage and content delivery, Open Connect. These meshes of user surveillance, predictive analytics, and infrastructural developments have ramifications beyond individual platforms and shape cultural production in extensive and increasingly problematic ways.

Vertebral osteomyelitis due to an unusual pathogen: a case report
Authors: Ghimire Rabindra , Hussain Jaffer , Abubaker Ahmed , Henderson Triona , Cook Paul
Published: April 2019

Background:

Vertebral osteomyelitis most often presents with back pain and is usually a secondary complication of a distant infection with hematogenous seeding. A source of infection is detected in about half of the cases. Burkholderia cepacia has rarely been implicated as an etiology.

Case Presentation:

We present a 50-year old Caucasian male with low back pain for 10 days associated with urinary incontinence without any fever or chills. He had laboratory and imaging evidence of vertebral osteomyelitis. Patient underwent bone biopsy and was diagnosed with vertebral osteomyelitis and discitis caused by B. cepacia. The patient was treated with intravenous meropenem for initial 2 weeks and, thereafter, oral ciprofloxacin and continues to do well several weeks later.

Conclusion:

Vertebral osteomyelitis due to B. cepacia has rarely been reported as a cause and though rare this organism should be considered in the differential diagnosis of vertebral osteomyelitis in the appropriate clinical setting.

WHAT MATTERS IN SELECTING A CAFÉ? A CASE OF MILLENNIALS
Authors: Firmansyah Egi Arvian , Nurjannah Fitria Atni , Indika Deru R , Gunardi Ardi
Published: April 2019

This paper aims to portray the criteria considered important by Millennials in selecting a café and investigate the gender preference regarding those criteria. The questionnaires were distributed to 100 café visitors. The research results using Rasch analysis showed that ‘comfort’ is generally the most important criterion of a café. Nonetheless, male and female Millennials do not always have a consensus where male Millennials prefer ‘innovativeness’ to other criteria while female Millennials prefer ‘comfort, varied menus, and unique menus’ to others. Other criteria aside from these four criteria are not significantly different among the two groups of gender. This paper gives implication for the culinary businesses in setting strategies targeting the Millennials who are presently the largest population group in Indonesia. This research also benefits any party interested in studying the characteristics and selection criteria of the Indonesian Millennials.

The Conversion of Waste CO2 to Intermediated Petrochemical Product
Authors: Piromchart Taradon , D’Elia Valerio
Published: April 2019

Excess anthropogenic CO2 emissions are a global environmental issue and a matter of concern for gas production in the Gulf of Thailand (GoT). The aim of this study is to develop a catalyst that can be used to convert CO2 obtained from a CO2 removal membrane by the cycloaddition reaction of CO2 to epoxides leading to industrially attractive cyclic carbonates. The results show that by using a suitable catalytic system, the reaction can be carried out in high yields under mild condition (Temperature range 25-120 °C and pressure range 4-9 barg). The conversion rate is 98 – 100% under optimized conditions.
Correlative Multiscale Imaging of Mancos Shale
Authors: Goral Jan , Deo Milind , Andrew Matthew
Published: April 2019

Mudstone (shale) reservoir evaluation and efficient development poses a significant challenge due to the heterogeneous nature of these complex formations. Organic-rich shales are characterized by intricate mineralogy, ultra-low nanoporosity, and nano-darcy permeability making these tight source/reservoir rocks challenging in obtaining economically viable hydrocarbons. Consequently, characterizing and quantifying minerology and intra-/interparticle (non)organic-hosted porosity at the pore-scale, and up-scaling it to the core-scale remains a significant focus of evaluating reservoir quality in shale plays.

Current advances in correlative multi-scale and multi-modal 2D/3D imaging of nanoporous geomaterials, such as shales, provide a tremendous opportunity to characterize and represent these rocks over multiple length scales – from core-to pore-scale. Subsequently, these image datasets can be then used for advanced image analysis and digital rock modeling to reconstruct 2D/3D models used to analyze their petrophysical properties.

In this study, the Mancos Shale from the Uinta Basin – one of the most promising shale plays in the United States (Hawkins et al. 2016) – was characterized from centimeter-to nanometer-scale via digital rock analysis using correlative micro 3D X-ray computed tomography (micro-CT), micro 3D X-ray microscopy (micro-XRM), light microscopy (LM) mosaic map, scanning electron microscopy (SEM) mosaic map, and focused ion beam (FIB) – SEM (FIB-SEM) nano-tomography image datasets. These multi-resolution and multi-dimensional image datasets, were then registered with each other, and used to reconstruct digital rock 2D/3D models from which shale petrophysical properties such as lithology, mineralogy, and porosity were extracted. Additionally, the imaged mineralogy and porosity results were compared with traditional laboratory experimental data, such as XRD and helium porosity measurements.

As part of the redevelopment plan, ‘S’ field was the first field selected for an end-to-end asset management Integrated Operations (IO project) where multiple workflows have been implemented for the asset operation optimization through monitoring and surveillance. One of the exclusive workflow that will be further elaborated in this paper is on Candidate Selection and Reservoir Optimization.

Although field optimization mission was ongoing, proper knowledge capture and standardization of such techniques were not adequate due to the limited data management. Lack of decision-support mechanism and most importantly the challenge was of understanding and analysing the asset performance. A key to the success of field and reservoir optimization is defining a tailored approach, for selection of right candidate and collaborative decision for well/field intervention.

With an objective of full field revitalization, the project was focused on integrated, collaborative 3R approach – Reliability, Reusability and Repeatability. Reliability component was based on capturing knowledge from experienced professionals from various domains and blending that with traditionally proven analytical techniques. Reusability was emphasized by the development of consistent and robust analysis workflows ready to use. Repeatability was aiming at standardizing the process of candidate selection and decision making to assist junior engineers.

The velocity model is of a great importance for geological as well as structural properties of complex structure such as gas cloud. Instead of ray-based techniques, eikonal wavefield tomography can provide a higher resolution velocity model for seismic images. We have implemented first break travel time tomography to enhance the initial velocity model for seismic full waveform inversion (FWI) for better imaging rather than guess initial velocity model for FWI. The First-break travel time concept is based on the eikonal equation, relies on inversion to resolve the complex gas cloud imaging. It allows not only the receivers but the shots to change position along the ray path. Tomography results are useful particularly significant in the presence of noise, scattering in the data. We have implemented this approach on marmousi as well as gas cloud model and output are used as input velocity model for FWI and results of proposed approach is more robust than the traditional with faster convergence.

The relative permeability test (RPT) plays an important part in production prediction, the law of water cut increasing analysis, the research on recovery factor and the reservoir numerical simulation. The residual oil saturation is one of the most significant parameters of RPT. While literature on the quality control of RPT is limited, the experimentalists make qualitative judgments on the rationality of the key data estimate based on their own experience. A new method is presented to predict residual oil saturation of light oil reservoirs.

Published: April 2019

Tight oil is more and more important in petroleum industry. However, there is few systematic studies up to now. Based on core data, petrophysical experimental data, well logs and test data, a systematic study on seven-property relation of tight oil reservoirs is conducted in Lucaogou Formation, Permian, Jimusaer Sag, Junggar Basin, China. To be specific, firstly, lithology is identified via cross plot of matrix density and constructed structure index from nuclear magnetic resonance (NMR) log. Secondly, using iteration method, lower limit T2 relaxation time value of effective pore and oil-filled porosity are calculated to be 1.7 ms and 7 ms respectively, which is a new way to predict porosity and oil saturation in tight oil reservoirs. Thirdly, high resolution resistivity (Rt) curve is acquired from micro-resistivity imager log by dimension reduction process and piecewise calibration. Total organic carbon (TOC) content is predicted by curve overlapping method of interval transit time (AC) and the obtained high-resolution resistivity. Fourthly, according to the transformation of dynamic and static rock mechanics parameters, an improved method is proposed for quantitatively predicting brittleness index (BI) of rocks via well logs. Ground stress value and direction are evaluated by various methods comprehensively. This study obtains a good application effect and provides important technical support for evaluating tight oil reservoirs via well logs, which plays an important role in tight oil exploration and development and new oil field discovery.
Effect of Pore Pressure Depletion on Wellbore Stability and Hydraulic Fracturing in Sandstone Reservoir

Published: April 2019

Development of stress sensitive reservoirs, especially in challenging environment, is raising awareness that geomechanics is a vital aspect of reservoir management. Understanding reservoir geomechanical behavior becomes more and more important for petroleum industry. A significant changes in formation pressure caused by depletion will induce deformation and stress/strain changes in the reservoir and the surrounding formation, understanding in-situ stresses and how stress changes in and around the reservoir due to depletion is important in a multidisciplinary approach to reservoir characterization and management.

These changes in stresses/strain affect the reservoir as well as the overburden and underburden formation, which directly affect drilling and stimulation operations strategies. Reservoir compaction, shear casing and well damage, cap-rock integrity, fault reactivation and sand production can occur during reservoir depletion.

To address these issues, 3D geomechanical models have been developed (which describe the state of stresses in the reservoir and overburden). 4D geomechanics models (dynamic models, that describe the changes in stress over time with production are required.

Reservoir Geomechanics approaches, this paper address and answer the following questions:

How Geomechanics changes in stresses and strain impact wellbore stability related issues and stimulation operations?

Stress rotation around faulted zones.

How depletion effect hydraulic fracture growth?
Wellbore Failure Modelling Using a Modified Drucker-Prager Criterion
Authors: Younessi Ahmadreza
Published: April 2019

The failure around the wellbore is studied using a modified form of Drucker-Prager failure criterion (MDP). The MDP has a linear shear failure envelope in the meridian plane and a curve-sided triangular failure curve in the deviatoric plane which can be controlled by the yield stress ratio (K). The model is compatible with the rock strength measurements under true-triaxial stress conditions similar to the modified Lade (MLa) failure criterion.

The MDP is used for stress modelling and wellbore stability analyses. The stress modelling is done by calculating the magnitude of maximum horizontal stress (SHmax) from the observed failure in the image log. The stress modelling result is compared with the results from the Mohr-Coulomb (MC), Drucker-Prager (DP), and modified Lade (MLa) criteria. The MDP is also used for wellbore stability analysis using both analytical and numerical (finite element) approaches. The analytical approach is used to conduct a sensitivity analysis to investigate the impact of well trajectory on minimum required mud weight. The finite element analysis is conducted to investigate the dimension of the breakout developed under different mud weights. The results are compared against the other failure criteria.

The SHmax magnitude calculated from the MDP model falls between the MC and DP. The analysis shows that the MDP with K = 0.778 is compatible with the MLa results for a rock with an internal friction angle close to 30° for both SHmax magnitude modelling and minimum required mud weight calculations for the wellbore stability analysis.

The results from the finite element analyses shows that the calculated breakout widths and depths using the MDP model falls between the MC and DP models. The analysis shows that in the presented case, although the calculated breakout width is large, the depth and amount of failed material around the wellbore are relatively small to create any wellbore instability problems. Hence, a mud weight relatively lower than calculated required mud weight from the analytical approach can be used in practice to drill the well. The results show the importance of considering the depth of the breakouts in the mud weight design.
