Authors: Amorim Marta Élid , Pietropaolo Ruy César , Galvão Maria Elisa Esteves Lopes , Garcia Silva Angélica Da Fontoura
Published: October 2020

Context: One of the challenges in the initial of mathematics teachers is to articulate the contents studied in the disciplines at the university with the themes of Basic Education. Objectives: to analyse, in the light of the assumptions established by Ball, Thames, and Phelps, the knowledge base for the teaching of Diophantine Equations of a group of future mathematics teachers participating in an experience of a teaching sequence. Design: the principles of the Design Experiments methodology were observed. Environment and participants: The study involved a group of ten students of the Mathematics Teaching Degree Course of a campus of the Federal University of Sergipe. Data collection and analysis: We analysed the reflections of the group of undergraduates, written records and audio recordings, generated by the experience of a teaching sequence on Diophantine Equations, which explored the relationship between a content of the Theory of Numbers and themes that would be taught in Basic Education. Results: The results show that the experience of the sequence provided the group of undergraduates with reflections on the difficulties that Basic Education students may have in situations involving equations and on how teachers could help students overcome them. Conclusions: Throughout the process, we observed advances in the understanding of the mathematical object, expanding the teaching professional knowledge base of the participants on the subject. This study concluded that a broader focus on the discussions to be promoted in the initial teacher education is needed to include and emphasise the relationship between the contents seen in the specific disciplines of Mathematics and those that will be taught in Basic Education.

Published: October 2020

Introduction.The burden of urinary tract infection (UTI) in pregnancy has been understudied in Cameroon.

Aim:to determine the prevalence and risk factors of UTI in pregnancy in a tertiary hospital in Cameroon.

Materials and methods.A hospital-based matched case-control study of pregnant women with evidence of UTI and those without who underwent antenatal care and gave birth at the Douala General Hospital from January 2014 to December 2018. Demographic, reproductive health/clinical data were collected using a pre-tested questionnaire and analyzed with SPSS.

Results.The prevalence of UTI in pregnancy was 4.41 %. Poor antenatal care uptake (AOR = 5.64; 95 % CI = 2.21–14.33), multiple weekly sexual intercourses (AOR = 4.64; 95 % CI = 0.22–96.94), a history of UTI (AOR = 3.01; 95 % CI = 1.12–8.04) and drying the genitals from back to front (AOR = 5.50; 95 % CI = 1.95–15.44) were associated factors.

Conclusion.The prevalence of UTI in pregnancy is low amid multiple associated factors. Screening for UTI in pregnancy should be made the standard of obstetric care in Cameroon.

The article presents the results of the work of the “Education for Children” Section of the Council under the Government of the Russian Federation on the Issues of Guardianship in the Social Sphere, which was carried out in the main areas of analysis, development and solution of the problems of professional training for working with vulnerable categories of the population: experience in applying professional standards for specialties in the social sphere, which are of a cross-sectoral nature; issues of professional training of specialists in accordance with the requirements of interdepartmental professional standards; problems of professional training of specialists in the education system to work with vulnerable categories of children; forms of work with the difficulties of children with special educational needs, their parents and teachers, due to the distance learning regime; requirements for the training of specialists in the social sphere for work in new social conditions. Based on the results of the analysis, a model for the formation and development of interprofessional competencies of social workers, based on the development of the best social practices, is discussed as a strategic direction for improving the training system. The presence of interprofessional competencies will allow specialists to act in concert and work in interdisciplinary teams, apply the best social technologies that have proven their effectiveness when working with vulnerable categories of the population. Within the framework of this direction, priority tasks have been identified to improve the system of professional training of such specialists.
Actual Problems of Training Specialists in the Field of Deviant Behavior Prevention in Educational Institutions
Authors: Bogdanovich N.V. , Delibalt V.V.
Published: October 2020

The article considers the challenges faced by psychologists of educational institutions as subjects of the prevention of juvenile delinquency, primarily the very understanding of prevention as a psychologist’s activity; it reveals why the everyday idea of psychoprophylaxis does not work in modern conditions and a comprehensive, even systemic understanding of this activity is required. It is necessary to consider several levels of support for this activity, from environmental to methodological support for the activities of the psychologist himself and the development resources of his personality. The activity system schema of I. Engestrim (Yrjö Engeström) is used to create such a model of a specialist (psychologist engaged in psychoprophylaxis) who could really carry out preventive activities at a high level. All elements of this model are described in detail: an object (goal), rules, division of labor, community, tools and subject. Based on this, the basic competencies of the psychologist of the system for the prevention of deviant behavior of adolescents are determined.
An Efficient Approach of Data Adaptive Polarization Filter to Extract Teleseismic Phases from the Ocean-Bottom Seismograms
Authors: Negi Sanjay S. , Kumar Amit , Ningthoujam Lachit S. , Pandey Dhananjai K.
Published: October 2020

The microseism is the strongest component of background seismic noise that masks seismic signals recorded by ocean-bottom seismographs (OBSs). Such undesired noise hampers the identification of critical seismic phases and sometimes even the entire waveform. Here, we introduce the data adaptive polarization filter (DAPF), an approach that suppresses random signals from the background seismic-noise significantly to overcome such difficulties. To automate this task, we have developed a self-contained software suite—DAPF-v1, supported by a MATLAB graphical user interface. The polarization filter is constructed from the data spectral density matrices of seismogram segments employing multitaper spectral analysis approach. We demonstrate a successful application of this technique to the OBSs deployed in the Indian Ocean. Our results confirm substantially enhanced signal-to-noise ratio after application of DAPF. The application of this technique has extensive implications for seismological studies particularly those aimed at understanding deep mantle dynamics, in which phase identification and qualitative waveform recovery are crucial yet challenging.

“Risky Forays into Border Lands”: „Bez autorytetu” by Stefan Chwin and Stanisław Rosiek, and the Depleting Modernity
Authors: Kaliszuk Przemysław
Published: October 2020

The article concerns a critical book by Stefan Chwin and Stanisław Rosiek, titled Bez autorytetu, which is treated as an example of the process of a certain turn in the Polish modern literature of the end of the 20th century. The author discusses the basic assumptions of critical concepts and indicates the questionable places of the problem structure emerging from those assumptions. In so doing, he treats Bez autorytetu as a form of a modern essay which developed in the conditions of mature modernism, which was reflected in the various attempts at transcending modernistic conditions, both formal and conceptual.
The Essays of Contaminated Landscapes
Authors: Tomczok Paweł
Published: October 2020

The article presents an analysis of the essayistic knowledge about genocide. For this purpose, the author used works by Martin Pollack. Further, the article indicates the intertwining of two threads in Pollack’s prose. The first one is the history of his family, recollections about Nazi relatives, and the dissonance which formed inside him regarding his family’s past. The other one is the study of space understood as uncovering its “contamination”, the sinister past which has marked the specific portion of the landscape. The aim of the article is to check whether it is possible to decontaminate, i.e. expunge that contamination from these landscapes in order to make them once again locations which foster life rather than are mere empty cemeteries.
Essay as the Autobiographical Heresy
Authors: Tomczok Marta
Published: October 2020

This article discusses the special kind of Holocaust essay which, on the one hand, remains in opposition to academic texts and, on the other, is a text which resembles an autobiography, and which reveals its author’s personal engagement in the discussed problem. By analysing Jan Tomasz Gross’ study titled Ten jest z ojczyzny mojej..., ale go nie lubię and its consecutive printed versions, the author of this article discusses the benefit of engaging in essay-writing for the scholar, who fluctuates between the academic and non-academic discourses. To this end, she also discusses other Polish Holocaust essays published in the mid-1980s (by, e.g., Jan Błoński and Roman Zimand) and the theory of the essay by Theodor W. Adorno, which triggered Gross’ formal and notional search.

The Battle of the Skamander
Authors: Kącka Eliza
Published: October 2020

The article offers a reconstruction of the text-based fight between Adolf Nowaczyński and Antoni Słonimski. It was not, as it is argued here, only a contest of styles and temperaments – though this exchange proved one of the most impressive, powerful, and dramatic polemics of that time in terms of articulation. However, it stemmed from a long history of tumultuous contacts which offered an amplified view of the problems of identity (Jewishness), politics, and community. A comprehensive view of the combat between Nowaczyński and Słonimski requires both an analysis of the rhetorics of the texts and an investigation into the context and dynamics of publication.
Words and Herbs: Julian Tuwim and the Poetry of Mindfulness
Authors: Roszak Joanna
Published: October 2020

In this article, the author discusses the subject of pro-peace education with the use of poetry, and its influence on the mental well-being of children. She indicates Julian Tuwim as one of the Polish trailblazers of the 20th-century trend of mindfulness, which instructs how to establish a harmonious relationship with oneself and the environment. She discusses studies which focus on the methods used when working during school lessons of the Polish language; methods which employ mindful poetry. The author argues that there exists a relationship between internal equanimity and global peace.

PALAEOCLIMATE RESEARCH OF MOUNTANEOUS ECOSYSTEMS BY USING THE METHOD OF INTEGRATED GROUP BIOLOGICAL ANALYSIS
Authors: Skripnikova M. , Uspenskaya O.
Published: October 2020

Methodological issues of climate change reconstruction in different Holocene periods are considered by the method of complex group biological analysis of peat and sapropel deposits. The possibilities of the method are demonstrated by reconstructing the climate of the Carpathian and the Altai mountain systems. For the Skolevsky Beskids of the Carpathians, paleoclimatic scenarios were prepared in order to clarify the climatic conditions during the periods of mass terracing of mountain slopes. A climatic paleoscenario was built for the Western Altai to forecast the safety of the bronze barrows with permafrost inside designs.
NORMS OF CHANGE OF PHYSICAL PROPERTIES OF SOILS OF STEPPE, ARID AND SEMI-DESERT ZONES OF EUROPEAN RUSSIAN TERRITORIES
Authors: Kuznetsova I. , Azovtseva N. , Bondarev A.
Published: October 2020

Norms of change of physical properties of arable land have been developed chernozems of steppe, chestnut soils of dry-steppe and light-chestnut soils of desert steppe zones of the European territory of Russia depending on the nature of anthropogenic impact. The limits of optimum, admissible and critical values of physical properties of these soils for growth and development of plants are established. For each zone, expert estimates of the distribution of soil areas with optimal, acceptable and critical values of the basic physical properties of soils are given. The greatest differences are observed in the density and structural composition of soils of different soil-climatic zones. In the steppe zone, soils with optimal values of arable layer density prevail among ordinary chernozems (1.0 - 1.2 g/cm3); among pre-Caucasian and southern chernozems - with values of 1.25-1.35 g/cm3. Among the chestnut soils of the dry-steppe zone the most common are the differences in the permissible values equilibrium density (1.30-1.40 g/cm3); in the desert steppe zone light chestnut soils with permissible (1.35- 1.45 g/cm3) and critical values (>1.45 g/cm3) of the equilibrium density. In the arable layer of soils of each separate zone agrophysical properties are significantly reduced by agrotechnical measures and close requirements of crops cultivated in the zone. Norms of change of physical properties can serve as a guide for assessing the current physical condition of arable soils and a basic basis for the development of regional fertility conservation and reproduction systems of the soil.

Authors: Lebedeva I.
Published: October 2020

Absence of regularity is shown and its reasons for spatial changes in quantitative parameters of humus accumulations and boiling depth from HCl are revealed; in this connection, their inadequacy as dividing lines of typical, ordinary and southern chernozems is grounded. The proposal to differentiate the considered group of chernozem subtypes on the basis of qualitative indices, first of all - features of carbonate profiles, most adequately reflecting the originality of modern regimes is considered.
The effect of global warming on soil salinity in arid regions
Authors: Pankova Ye. I. , Konyushkova M. V.
Published: October 2020

The comparison of modern climatic conditions and soil salinity in subboreal deserts of Middle Asia (Turanian plain) and Central Asia (Gobi deserts) shows that climate has an effect on salinity of hydromorphic soils. From the other hand, the distribution and degree of salinity of automorphic desert soils are predominantly governed by the distribution of salt-bearing rocks inherited from the previous geologic stages and are not related directly to the modern aridity. This fact allows us to state that the global warming will not promote salinization of automorphic soils of arid regions, except for the soils subjected to aeolian salinization. Climate aridification will provoke soil salinization in hydromorphic conditions.
Open soil surface brightness as a direct sign for soil recognition on LANDSAT images
Authors: Savin I. Yu.
Published: October 2020

The variability of the brightness heterogeneities of the open chernozemic soil surface on LANDSAT images obtained in different seasons and different dates of survey were investigated. The brightness of the images (3 band) was unstable and considerably changes from one period of survey to another even within the one season of the year. Obtained results lead to the conclusion that during the automated recognition of soils on the satellite images the analysis of brightness of single image cannot serve as reliable basis for the digital soil mapping.
Organizational mechanisms of tectology in soil science
Authors: Rozhkov V. A.
Published: October 2020

Under discussion are basic concepts, methods and prerequisites for applying in pedology such a general science as tectology founded by A.A. Bogdanov, an eminent Russian scientist, in the early 20th century. Tectological, i.e.organizational approach proved to be efficient in formalization, in cartographic and attributive description of soil objects and in elaboration of the classification structure. A new conception is universal in its application and many aspects of soil science may be considered in tectological context (systems, structures). However, there is a weak spot in formalization of concepts, what has been implemented by theoretic-plural means, multidimensional statistics and claster analysis.

Authors: Muromtsev N. A. , Shuravilin A. V. , Semenov N. A. , Anisimov K. B. , Tabuk Musalem
Published: October 2020

The paper is devoted to the analysis and evaluation of peculiar features of the water regime in loam-sandy soils of Oman. The total water volume taken up by potatoes has been determined in different modes of pre-irrigation soil moisture (70, 80% of MWC and 70-80-70% of MWC) and in dependence on the water-holding layer consisting of natural materials. It is shown that the most favorable conditions for water supply of potatoes, taking into account the economical use of irrigation water, can be created by differentiation of pre-irrigation soil moisture in inter-phase periods at a level of 70-80-70% of minimum water capacity (MWC). At the same time, sapropel should be used as a water-holding layer, which increases the potatoes yield at least by 10%.
Methodology of land resources assessment for agricultural production in russia (at the example of hop cultivation
Authors: Ivanov A. . , Savin I. . , Egorov A. .
Published: October 2020

Original methodology for land evaluation was elaborated as based on GIS technologies and FAO land evaluation approaches. Unique register of soil resources of Russia was used as a basis for land suitability analysis for hop cultivation in Russia. Optimal territories for hop cultivation occupy in Russia only 0.01% of lands. Greatest constraints for hop cultivation are associated with the soil and climatic conditions. The smallest potential expenditures for the cultivation of hop are expected for the territory of European Russia, the south of West Siberia and in the Far East on the “warm” plains. The greatest investments will be required for the cultivation of hop in the mountain regions of the Urals, Altai, in the mountains of East Siberia and Far East.

Under consideration are results of studying an actual and very important problem related to dangerous underground flood processes and their occurrence in southern regions of European Russia. A comprehensive analysis was made to identify reasons for the development and intensity of such processes. It is shown that the underground flood processes become more intensive due to human activities in the sphere of water-power engineering. A system of measures is proposed how to protect the lands from the underground flood represented by a complex of preventive measures to maintain the optimal water-air regime in soils and to remediate their productivity.

Authors: Coutinho e Silva Andreia , Rigoni Adriana , Vasconcelos Flavia Nico , Lucas Luiza Kister
Published: October 2020

Trata-se de uma pesquisa com finalidade descritiva, destinada a analisar as relações entre uma entidade portuária e a comunidade do entorno. Para isto, realizou-se entre os meses de outubro a dezembro de 2017 pesquisas de campo com entrevistas à CODESA e arrendatárias a fim de identificar como se estabelece a comunicação entre elas e a comunidade situada no entorno do porto de Vitória. Pode-se concluir que a CODESA, por ser uma autoridade portuária, disponibiliza canais de comunicação para a comunidade civil do entorno, mas sem realizar ações a partir das demandas dela. Isso também acontece com as arrendatárias, que também demonstram que não possuem relações de proximidade com as comunidades do entorno.
Uma análise dos dizeres sobre a voz de sucesso midiático
Authors: Soares Thiago Barbosa
Published: October 2020

Este artigo tem por objetivo analisar discursos produzidos e veiculados pela mídia brasileira contemporânea sobre o que se poderia chamar de as vozes do sucesso midiático. Mais precisamente, são descritos e interpretados os procedimentos de produção de sentidos em enunciados constituídos e formulados no interior do discurso midiático brasileiro que trata manifestamente da voz de sujeitos cujo sucesso decorre em princípio de seu desempenho vocal. Desse modo, ao ser considerado o postulado da Análise do Discurso, formulado por Pêcheux, de que sujeito e sentido se constituem ao mesmo tempo no movimento histórico, entende-se que os dizeres acerca da voz de sucesso produzem, concomitantemente, os sentidos e os sujeitos que circulam socialmente. Ante esse quadro estruturante, foi investigado o que se diz e como é enunciada a voz no discurso do sucesso, na atual sociedade brasileira e as diferenças no tratamento dispensado à voz daqueles que figuram no mundo midiático, em específico, quais distinções podem existir no tocante à produção de sentidos das vozes de sucesso midiático quando disseminadas pelo mesmo veículo de difusão. Para tanto, contamos com dois textos da revista Carta Capital, publicados respectivamente em 2013 e em 2015.
The religious factor in Nigeria’s 2019 Presidential election
Authors: Ojo Emmanuel O
Published: October 2020

This study analyses the nexus between religion and political behaviour in Nigeria’s 2019 presidential election, and the effect on voting behaviour and patterns across the country. The extent of religious cleavages remains substantial and has not diminished over the years. These cleavages follow the Christian/Muslim divide, aside from the denominational differences in Europe and America or the ethnic pluralism in many African states. The impact of indigenous African religions is negligible because there are too many for consideration. This article therefore contributes to the recent resurgence of interest in religion and politics, with the fundamental research question being: does democracy need religion? The paper infers that Nigeria’s nascent democracy must promote a secular state, particularly in the face of the deep ethnic and religious differences that are capable of bringing about a democratic reversal to autocracy and absolutism if not well managed.

The Accuracy Validation of FireFACE Software in Analyzing Facial Expressions of Urban Forest Visitors
Authors: Wei Hongxu , Liu Ping
Published: October 2020

The construction of sustainable urban forests follows the principle that well-being in people is promoted when exposed to tree population. Facial expression is the direct representation of inner emotion that can be used to assess real-time perception in urban forests. The emergence and change of facial expressions for forest visitors are in an implicit process. The reserved character of oriental races strengthens the requirement for the accuracy to recognize expressions through instrument rating. In this study, a dataset was established with 2,886 randomly photographed faces from visitors in a constructed urban forest park and a promenade at summertime in Shenyang City at Northeast China. Six experts were invited to choose 160 photos in total with 20 images representing one of eight typical expressions as angry, contempt, disgusted, happy, neutral, sad, scared, and surprised emotions. The FireFACE ver. 3.0 software was used to test hit-ratio validation as the accuracy (ac.) to match machine-recognized photos with those identified by experts. According to Kruskal-Wallis test on the difference from averaged scores in 20 recently published papers, contempt (ac.=0.40%, P=0.0038) and scared (ac.=25.23%, P=0.0018) expressions cannot pass the validation test. Therefore, the FireFACE can be used as an instrument to analyze facial expression from oriental people in urban forests but contempt and scared expressions cannot be identified.

This study aimed at evaluating changes in the clinical and echocardiographic parameters of pregnant sheep, as well as the HRV indexes due to the physiological alterations that happen at this stage implicating in high maternal metabolic demands. For this purpose, the study evaluated 10 Dorper sheep through their pregnancy, starting from the second month until the day before birth, conducting clinical, echocardiographic and electrocardiographic examinations focused on the HRV. The echocardiogram was conducted in a doppler ultrasound device with a multifrequency sectorial transducer in bidimensional mode. The HRV indexes were obtained through the Televet 100® system. There were increases in the thickness of the interventricular septum during diastole starting from the third month, and in the internal diameter of the left ventricle during systole and diastole at the second and third months, while the ejection fraction increased as the pregnancy progressed. The size of the left atrium increased starting at the second month. The SDNN, RMSSD and PNN50 HRV indexes were higher at the fifth month of pregnancy and after delivery. There were no significant differences in the frequency-domain HRV indexes during pregnancy. The gestation leads to alterations in the clinical parameters and the activity of the autonomic nervous system.
Nomothethic Network Psychiatry: A Bottom-Up Approach to Build Data-Driven Disease Models Based on Risk-Resilience, Adverse Outcome Pathways, and Phenome Scores, and to Discover New Biosignature-Based Classifications
Authors: Stoyanov Drozdstoy , Maes Michael
Published: October 2020

Psychiatry remains in a permanent state of crisis, which fragmented psychiatry from the field of medicine. The crisis in psychiatry is evidenced by the many different competing approaches to psychiatric illness including psychodynamic, biological, molecular, pan-omics, precision, cognitive and phenomenological psychiatry, folk psychology, mind-brain dualism, descriptive psychopathology, and postpsychiatry. The current “gold standard” DSM/ICD taxonomies of mood disorders and schizophrenia are unreliable and preclude to employ a deductive reasoning approach. Therefore, it is not surprising that mood disorders and schizophrenia research was unable to revise the conventional classifications and did not provide more adequate therapeutic approaches. The aim of this paper is to explain the new nomothetic network psychiatry (NNP) approach, which uses machine learning methods to build data-driven causal models of mental illness by ensembling risk-resilience, adverse outcome pathways (AOP), cognitome, brainome, symptomatome, and phenomenome latent scores in a causal model. The latter may be trained, tested and validated with Partial Least Squares (PLS) analysis. This approach not only allows to compute pathway-phenotypes or biosignatures, but also to construct reliable and replicable nomothetic networks, which are, therefore, generalizable as disease models. After integrating the validated feature vectors into a well-fitting nomothetic network, clustering analysis may be applied on the latent variable scores of the R/R, AOP, cognitome, brainome, and phenome latent vectors. This pattern recognition method may expose new (transdiagnostic) classes of patients which if cross-validated in independent samples may constitute new (transdiagnostic) nosological categories.

Nowadays, model checking is applied as an accurate technique to verify software systems. The main problem of model checking techniques is the state space explosion. This problem occurs due to the exponential memory usage by the model checker. In this situation, using meta-heuristic and evolutionary algorithms to search for a state in which a property is satisfied/violated is a promising solution. Recently, different evolutionary algorithms like GA, PSO, etc. are applied to find deadlock state. Even though useful, most of them are concentrated on finding deadlock. This paper proposes a fuzzy algorithm in order to analyze reachability properties in systems specified through GTS with enormous state space. To do so, we first extend the existing PSO algorithm (for checking deadlocks) to analyze reachability properties. Then, to increase the accuracy, we employ a Fuzzy adaptive PSO algorithm to determine which state and path should be explored in each step to find the corresponding reachable state. These two approaches are implemented in an open-source toolset for designing and model checking GTS called GROOVE. Moreover, the experimental results indicate that the hybrid fuzzy approach improves speed and accuracy in comparison with other techniques based on meta-heuristic algorithms such as GA and the hybrid of PSO-GSA in analyzing reachability properties.

In the present work we revise and extend the Characteristic Crystallographic Element (CCE) norm, an algorithm used to simultaneously detect radial and orientational similarity of computer-generated structures with respect to specific reference crystals and local symmetries. Based on the identification of point group symmetry elements, the CCE descriptor is able to gauge local structure with high precision and finely distinguish between competing morphologies. As test cases we use computer-generated monomeric and polymer systems of spherical particles interacting with the hard-sphere and square-well attractive potentials. We demonstrate that the CCE norm is able to detect and differentiate, between others, among: hexagonal close packed (HCP), face centered cubic (FCC), hexagonal (HEX) and body centered cubic (BCC) crystals as well as non-crystallographic fivefold (FIV) local symmetry in bulk 3-D systems; triangular (TRI), square (SQU) and honeycomb (HON) crystals, as well as pentagonal (PEN) local symmetry in thin films of one-layer thickness (2-D systems). The descriptor is general and can be applied to identify the symmetry elements of any point group for arbitrary atomic or particulate system in two or three dimensions, in the bulk or under confinement.
Engineering Fracture Geometry by Acknowledging Geological Heterogeneity to Maximize Productivity

Published: October 2020

Completion diagnostics have been extensively utilized in hydraulically fractured horizontal wells across all major basins to determine the effectiveness of stimulation strategies and to evaluate new technologies. They have also been key in understanding factors that drive well performance and reduce completion costs. Geological heterogeneity provides unique challenges and opportunities for completion optimization. Diagnostic data provide insights into fracture characterization under various geological conditions and how they can be utilized for well design and field development. This paper demonstrates the integration of geology with completion diagnostics results.

The dynamic relationship between evolving completion technologies and geology is brought to light with the help of case studies across multiple basins. The challenges studied include fracture driven interactions (frac-hits), perforation cluster design, landing zone optimization and production analysis. By incorporating geology into the diagnostic results, additional insights are obtained for enhanced reservoir characterization and future field development.

The case histories illustrate how the interpretation of diagnostic data can be strengthened by a combined understanding of geology and completion technologies, instead of employing an independent approach. In one instance, a high degree of fracture driven interactions (frac-hits) from new completions to existing producers was observed. Further detailed study of geological features in the section revealed that the frac-hits were primarily due to the presence of the faults rather than by well proximity and stimulation treatment volumes.

In another example, diagnostics data identify low hydrocarbon productivity across several stages within a well. The load fluid recoveries in these stages with low hydrocarbon flowback are comparable to better performing stages, indicating effective stimulation and flow capacity within the fracture. This underscores the importance of comprehensive lithology evaluation across the lateral to identify low productivity intervals, for improving future well placement and performance.

The outcomes of these case studies provide examples of the barriers between engineering and geology being broken through data corroboration. Asset level decisions surrounding the integration of multiple technical teams offer an opportunity to reduce the learning curve in basin development strategies. This study releases case studies across multiple basins that leverage this integration. The approach outlined in this paper can be applied in any horizontal field development program.

Published: October 2020

This study demonstrates the application of an interpretable (or explainable) machine learning workflow using surface drilling data to identify fracable, brittle and productive rock intervals along horizontal laterals in the Marcellus shale. The results are supported by a thorough model-agnostic interpretation of the input-output relationships to make the model explainable to users. The methodology described here can easily be generalized to real-time processing of surface drilling data for optimal landing of laterals, placing of fracture stages, optimizing production and minimizing frac hits. In practice, this information is rarely available in real-time and requires tedious and time-consuming processing of logs (including image logs), core, microseismic data and fiber optic sensor data to provide post-job validation of frac- and well-placement. Post-completion analyses are generally too late for corrective action leading to wells with a low probability of success and increasing risk of frac hits. Our workflow involves identifying geomechanical facies from core- and well-log data. We verify that the geomechanical facies derived using core- and well-log data have characteristically different brittleness, fracability and production characteristics. We test and investigate several different supervised classifiers to relate surface drilling data to the geomechanical facies. The data was divided into training and test datasets, with supervised classification techniques being able to accurately predict the geomechanical facies with 75% accuracy on the test dataset. The clusters predicted on test well (unseen data) were qualitatively verified using the microseismic interpretation. The use of Shapley Additive Explanations (SHAP) helps explain the predictive models, rank the importance of various inputs in the prediction of the facies and provides both local and global sensitivities. Our study demonstrates that pre-existing natural fracture networks control both the hydraulic fracture geometry as wells as the production. Natural fractures promote the formation of complex fracture networks with shorter half-lengths which increase well productivity while minimizing frac hits and neighboring well interactions. The natural fracture network is itself controlled by the geomechanical properties of the rock. The ability of the surface drilling data to reliably predict the geomechanical rock facies provides a powerful tool for real-time optimization of wellbore trajectory and completions.
A Data-Driven Water-Soaking Model for Optimizing Shut-In Time of Shale Gas/Oil Wells Prior to Flowback of Fracturing Fluids
Authors: Shaibu Rashid , Guo Boyun
Published: October 2020

This paper presents a method for identifying the optimum soaking time between the cessation of pumping, and the flowback of hydraulic fracturing fluids after a hydraulic fracture stimulation job, to increase productivity of shale gas and oil wells. Multiple cracks were observed at the surfaces of cores from a shale oil reservoir under simulated water-soaking conditions. The observation proposes a hypothesis that the formation of cracks should increase well productivity. Well shut-in pressure data recorded in a watersoaking process in a shale gas reservoir were employed to derive a mathematical model to describe the process of crack propagation in shale gas/oil formations. This crack model was incorporated in a well productivity model to form an objective function for selection of the water soaking time. A field case was studied with the mathematical model to proof the hypothesis and explore factors affecting the optimum water-soaking time. Analysis of the model shows a quick increase of well productivity with water-soaking time in the beginning followed by a trend of leveling-off. The water-soaking process is mainly controlled by the number of cracks along the bedding plane. High viscosity of fracturing fluid corresponds to longer soaking time, while increasing water-shale interfacial tension reduces the optimum soaking time. The effect of different initial water saturations on optimum soaking time was found to be insignificant. If real time shut-in pressure data are used, this technique can translate the pressure data to dynamic crack propagation data and "monitor" the potential well productivity as a function of water-soaking time.
