Spatial cognition research requires behavioral paradigms that can distinguish between different navigational elements, such as allocentric (map-like) navigation and egocentric (e.g., body centered) navigation. To fill this need, we developed a flexible experimental platform that can be quickly modified without the need for significant changes to software and hardware. In this paper, we present this inexpensive and flexible behavioral platform paired with software which we are making freely available. Our behavioral platform serves as the foundation for a range of experiments, and although developed for assessing spatial cognition, it also has applications in the nonspatial domain of behavioral testing. There are two components of the software platform, “Maze” and “Stim Trigger.” While intended as a general platform, presently both programs can work in conjunction with Neuralynx and Open Ephys electrophysiology acquisition systems, allowing for precise time stamping of neural events. The Maze program includes functionality for automatic reward delivery based on user defined zones. “Stim Trigger” permits control of brain stimulation via any equipment that can be paired with an Arduino board. We seek to share our software and leverage the potential by expanding functionality in the future to meet the needs of a larger community of researchers.
Pupil Size Sensitivity to Listening Demand Depends on Motivational State
Authors: Kraus Frauke , Obleser Jonas , Herrmann Björn
Published: November 2023

Motivation plays a role when a listener needs to understand speech under acoustically demanding conditions. Previous work has demonstrated pupil-linked arousal being sensitive to both listening demands and motivational state during listening. It is less clear how motivational state affects the temporal evolution of the pupil size and its relation to subsequent behavior. We used an auditory gap detection task (N = 33) to study the joint impact of listening demand and motivational state on the pupil size response and examine its temporal evolution. Task difficulty and a listener’s motivational state were orthogonally manipulated through changes in gap duration and monetary reward prospect. We show that participants’ performance decreased with task difficulty, but that reward prospect enhanced performance under hard listening conditions. Pupil size increased with both increased task difficulty and higher reward prospect, and this reward prospect effect was largest under difficult listening conditions. Moreover, pupil size time courses differed between detected and missed gaps, suggesting that the pupil response indicates upcoming behavior. Larger pre-gap pupil size was further associated with faster response times on a trial-by-trial within-participant level. Our results reiterate the utility of pupil size as an objective and temporally sensitive measure in audiology. However, such assessments of cognitive resource recruitment need to consider the individual’s motivational state.

Industrial and agricultural activities, as well as settlements, have changed many lacustrine environments, as recorded in lake sediments. In this study, concentrations of trace metals and rare earth elements (REEs), along with the mass-specific magnetic susceptibility measured at low frequency (470 Hz), termed χLF, were used to elucidate the anthropogenic impacts related to religious activities in 2 lakes (Buyan and Tamblingan) on Bali Island, Indonesia. The predominantly Hindu populations of Bali are known to hold various religious activities in puras, or Balinese temples, in these lakes. There are 8 puras in Lake Tamblingan and only 3 puras in Lake Buyan. In these religious activities, offerings, which might include metallic objects, were thrown into the lakes. Measurements on surface sediments from 20 locations in Lake Buyan and 16 locations in Lake Tamblingan show that χLF values and concentrations of trace metals and REEs are higher in the sediments of Lake Tamblingan compared to those of Lake Buyan, except for concentrations of SiO2 and Gd. The average χLF value of Tamblingan’s samples is 492.6 (±282.4) × 10−8 m3/kg, while that of Buyan’s samples is 372.0 (±246.6) × 10−8 m3/kg. The average concentrations of Fe and Al in Tamblingan’s samples are 5.934 and 4.941 (in % weight), respectively, while those of Buyan’s samples are 4.445 and 3.434 (in % weight), respectively. The average concentrations of Ce and Nd in Tamblingan’s samples are 2.066 and 1.494 (in ppm), respectively, while those in Buyan’s samples are 1.423 and 1.105 (in ppm), respectively. Concentrations of trace metals and REEs, as well as χLF, are higher in locations close to the puras around the lakes. For instance, the χLF of location T11 near Pura Dalem Tamblingan is 975.9 (±99.3) × 10−8 m3/kg, while the concentrations of Fe and Al in this location are 9.790 and 14.090 (in % weight). Furthermore, the Ce and Nd concentrations in T11 are 3.635 and 2.443 ppm, respectively. Based on these results, we can say that the surface sediments of Lakes Buyan and Tamblingan have been changed by human activities, mostly religious ones.

Published: November 2023

Protein requirements of eukaryotic cells are ensured by proteostasis, which is mediated by tight control of TORC1 activity. Upon TORC1 inhibition, protein degradation is increased and protein synthesis is reduced through inhibition of translation initiation to maintain cell viability. Here, we show that the ribosome‐associated complex (RAC)/Ssb chaperone system, composed of the HSP70 chaperone Ssb and its HSP40 co‐chaperone Zuo1, is required to maintain proteostasis and cell viability under TORC1 inhibition in Saccharomyces cerevisiae. In the absence of Zuo1, translation does not decrease in response to the loss of TORC1 activity. A functional interaction between Zuo1 and Ssb is required for proper translational control and proteostasis maintenance upon TORC1 inhibition. Furthermore, we have shown that the rapid degradation of eIF4G following TORC1 inhibition is mediated by autophagy and is prevented in zuo1Δ cells, contributing to decreased survival in these conditions. We found that autophagy is defective in zuo1Δ cells, which impedes eIF4G degradation upon TORC1 inhibition. Our findings identify an essential role for RAC/Ssb in regulating translation in response to changes in TORC1 signalling.

Published: November 2023

Este estudo, parte de uma investigação mais ampla sobre as transformações do exercício paterno na contemporaneidade, e teve como objetivo investigar a participação do pai durante a gestação, parto e pós-parto sob a perspectiva do homem. Para tanto, realizou-se uma pesquisa qualitativa, na qual foram entrevistados quinze pais primíparos. Os resultados foram analisados de acordo com o método de análise de conteúdo na sua vertente categorial. Da análise do material, emergiram diversas categorias de análise. Para atingir os objetivos formulados no presente trabalho, serão discutidas as categorias presença do pai nas consultas de pré-natal, presença do pai na sala de parto e rede de apoio familiar. Os resultados apontaram que, na atualidade muitos homens desejam participar do ciclo gravídico-puerperal, entretanto sua presença nem sempre é facilitada, em especial, devido aos estereótipos de gênero associados ao universo obstetrício como um espaço naturalmente feminino. Conclui-se que a participação do homem durante o pré-natal, parto e pós-parto é um fator positivo, pois fortalece os vínculos familiares.
Molecular Profile of Cogongrass [Imperata cylindrica (L.) Raeusch] in Java Island Based on trnT(UGU)-trnL(UAA) IGS Sequences

Published: November 2023

Cogongrass is one of the top ten problem-causing weeds in the world that is invasively spread over many tropical and subtropical regions, including Java Island, the Republic of Indonesia. The wide distribution is possibly related to their adaptability to almost all terrestrial habitats from various altitudes, which may lead to a high level of genetic variation.  This study aimed to assess the genetic variation and phylogenetic relationship of cogongrass in Java Island using an intergenic spacer (IGS) sequence in the cpDNA genome, i.e. trnT(UGU)-trnL(UAA), as the molecular marker of high mutation rate. Plant samples were collected randomly from five different sites on the island. These were subjected to total genomic DNA extraction. The DNAs obtained were then used as PCR templates to amplify trnT(UGU)-trnL(UAA) IGS using a pair of universal primers. The PCR products were sequenced for genetic analysis. It was shown that an extremely high genetic variation with respect to the haplotype diversity of cogongrass in Java Island was observed. Nevertheless, a very low nucleotide diversity was obtained revealing a considerably close genetic relationship among the samples. Anatomical data regarding stomata number and length were found to correspond to the high level of genetic variation, but it was not the case with the stomata index.
PORN LITERACY EDUCATION: É POSSÍVEL UMA EDUCAÇÃO SEXUAL CRÍTICA À PORNOGRAFIA NO CONTEXTO BRASILEIRO?
Authors: Messias Carolina Carrolo , Feitosa Lourdes Madalena Gazarini Conde
Published: November 2023

A pornografia tem cada vez mais ganhado espaço e participação na sexualidade humana, ainda mais com o avanço das tecnologias e da Internet. Todavia, os impactos da pornografia na sexualidade humana e a repercussão do tipo de pornografia de consumo rápido ocasionado pela Internet, não têm sido abordados na Educação Sexual brasileira. A necessidade de se falar sobre, contudo, urge devido ao seu alto consumo pelos brasileiros e pelas consequências negativas demonstradas em estudos em relação ao uso desse tipo de material. O presente artigo traz questionamentos quanto à implementação da porn literacy education – que se trata de um modo de educação sexual que se volta ao desenvolvimento de criticidade quanto ao consumo de pornografia no Brasil, pensando-se em relação à demanda, possiblidades e necessidades de adaptação à realidade sociocultural brasileira. Compreendeu-se a análise a partir de uma pesquisa bibliográfica, levantando dados quanto ao movimento antipornografia, a história da educação sexual no Brasil e as raízes da porn literacy education. O estudo considera, ainda, as perspectivas trazidas pelo movimento antipornografia por meio de duas representantes: Andrea Dworkin e Catherine Mackinnon. A porn literacy education demonstra-se como uma ferramenta em potencial para a educação sexual, mas que necessita de estudos mais aprofundados visando desenvolver um tipo de currículo e programa tipicamente brasileiro.

The aim of the study is assess the reliability, internal stability and effectiveness of adaptation of individual questions of the QAA-25 questionnaire to assess the potential adherence to treatment of persons aged 12–14 years, in comparison with a similar QAA-25 questionnaire for persons aged 15–17 years. Material and Methods. In a descriptive observational study, including 314 students of general schools in Omsk the level of treatment adherence was determined using the QAA-25 questionnaire, using traditional and alternative formulations of individual questions. Results. For adolescents aged 12–14 years a good diagnostic value was shown higher individual testing quality (absence of blank answers to questions) of the tested version of the questionnaire compared to the alternative one. 96.8% of respondents indicated that the wording of the specialized questionnaire was “more accurate” and “more correct”. The tested version of the questionnaire demonstrated good reliability (Cronbach’s alpha total 0.901, based on standardized items αst 0.914) with high internal consistency (consistent elimination of scale items maintains questionnaire validity in the 0.886–0.909 range), with near perfect expert agreement (Cohen’s kappa 0.908). Conclusion. The questionnaire is characterized by good validity and has a high internal stability, and the content and wording of all questions of the questionnaire are adequately perceived by the audience for which the questionnaire is designed. This makes it advisable to use it to assess the potential adherence to treatment of adolescents aged 12–14 years.

Background. The emergence of new functional capabilities of statistical accounting made it possible to conduct a comparative analysis of the morbidity of allergic pathologies according to the registers of allergists and pediatricians from the Unified Medical Information and Analytical System (UMIAS) of Moscow with data from the Form of Federal Statistical Observation No. 12 (FSO No. 12). The aim of the study is to investigate the potential of using UMIAS for assessing/monitoring the morbidity of allergic diseases, including bronchial asthma in children, using the example of several outpatient clinics (OPCs) in Moscow. Methods. A study of combined design has been carried out. The data of children of several OPCs in Moscow were analyzed — data from UMIAS (observation registers of pediatricians and allergist-immunologists) and from the reporting forms of the FSO No. 12. Results. For a comparative analysis of statistical data from UMIAS and FSO No. 12, we studied the information of 60,851 children under 18 years of age. It was revealed that out of 60,851 children: allergic rhinitis according to FSO No. 12 and UMIAS was established in 1001 and 1059 patients; atopic dermatitis — in 142 and 345; urticaria — in 363 and 33; angioedema — in 4 and 16, respectively; food allergy — in 233 children according (to FSO No. 12) and in none of the children (according to UMIAS). Out of 60,851 children, 619 children were diagnosed with bronchial asthma according to the annual report (FSO No. 12) and 537 according to the pediatrician’s observation registers (UMIAS). At the same time, it was found that the diagnosis of bronchial asthma is not available as a separate nosology in the registry of an allergist-immunologist, and information about children with bronchial asthma is available to this specialist only when analyzing the uploaded information about children with other allergic diseases. Conclusion. A adequate sample ensured a high representativeness of the results obtained. The differences in the incidence rates of allergic diseases revealed by a comparative analysis of data from various sources — UMIAS and FSO No. 12 — indicate the need to improve both the system of statistical registration of incidence and the development of modern algorithms for early diagnosis and dynamic monitoring of children with allergies.

Glycogen storage disease type Ib (GSD Ib) — is a disease from the group of hereditary metabolic diseases caused by insufficiency of the glucose-6-phosphate transporter (G6PT, SLC37A4), which leads to a violation of both glycogenolysis and gluconeogenesis and, as a consequence, to excessive accumulation of glycogen and fat in the liver, kidneys and intestinal mucosa. The main clinical manifestations and laboratory data include growth retardation, hepatomegaly, hypoglycemia, lactic acidosis, hyperuricemia and hyperlipidemia. Complications of this disease are hepatocellular adenoma with a possible risk of malignancy, nephropathy and osteoporosis. A specific sign of GSD Ib is neutropenia with impaired neutrophil function, which creates prerequisites for recurrent infections and the development of inflammatory bowel disease. Until the present, enzyme replacement therapy of GSD Ib has not been developed, therefore, the main methods of treatment are a specialized diet with the addition of raw corn starch (for relief of hypoglycemia) and the use of granulocyte colony stimulating factor (for relief of neutropenia). However, the recent establishment of the role of 1,5-anhydroglucitol in the pathogenesis of neutrophil dysfunction in GSD Ib has led to a reprofiling of indications for the use of empagliflozin, a type 2 renal sodium—glucose cotransporter inhibitor (SGLT2). In the modern literature, it is reported about a minor, but very successful experience of its use in patients with GSD Ib (outside the framework of official indications for use) and a beneficial effect on neutrophil dysfunction and its clinical consequences. Oddly enough, this hypoglycemic drug improved not only metabolic, but also glycemic control in patients with GSD Ib, despite the fact that the pathology is based on chronic hypoglycemia. More and more evidence points to the role of empagliflozin in the regulation of cellular homeostasis (for example, fatty acid metabolism, glucose, cholesterol, apoptosis and cell proliferation, in particular in the liver) by influencing the activity of sirtuin 1 (SIRT1), AMP-activated protein kinase (AMPK) and signal molecules such as -serine/threonine protein kinase (Akt) and a mechanical target of rapamycin (mTOR), which leads to an improvement in the structure and function of mitochondria, stimulation of autophagy, reducing oxidative stress and suppressing inflammation. Modulation of these pathways shifts oxidative metabolism from carbohydrates to lipids and leads to a key decrease in insulin levels, resistance to it, glucose and lipotoxicity. This review presents current data on the pathogenesis of neutropenia and the possibility of using empagliflozin for its relief in patients with GSD Ib.

The study data of the last two decades on primary and secondary immunodeficiency in congenital heart defects (CHD) as a cause of frequent infectious complications before and after cardiac surgery are presented. Based on screenings of various levels, data are provided on the greater severity of immunological disorders in critical and cyanotic CHD in conotruncal defects compared with those in septal defects and stenotic defects. Violations were more often related to T-cell function and immunoglobulin deficiency (especially the IgG and IgG4 subgroups). Various types of primary immunodeficiency were found in 13 genetic syndromes in combination with CHD. The review discusses the possibility of using the technique of quantitative determination of DNA TREC and KREC — by-products of maturation of T- and B-cell receptors, which allows us to judge the defects of the T- and B-cell links of the immune system to predict infectious complications in children with CHD. The data of our own study of 200 infants with CHD (in 5% of cases with syndromic forms of CHD) are presented, where a decrease in TREC was found in 23.5% of cases, including all infants with syndromic forms, more often with cyanotic and conotruncal CHD and in children admitted in critical conditions. In children with reduced TREC values, infectious complications in the postoperative period were observed significantly more often than in children with normal indicators (36 and 3.6%, respectively). The analysis of publications confirmed the importance of TREC and KREC screening for targeted preoperative preparation in order to reduce postoperative complications and reduce the risk of mortality in CHD.
Waste electrical and electronic equipment flows in Ukraine
Authors: Ishchenko Vitalii , Sydoruk Tetiana
Published: November 2023

This paper estimates the weight of electrical and electronic equipment on the Ukrainian market (more than 800 thousand t/year). According to official statistics, weight of waste electrical and electronic equipment (WEEE) in Ukraine is ∼20 thousand t/year. This study has showed a significant discrepancy between the expected weight of WEEE and official statistics. More than 95% of WEEE is not taken into account in waste flows. Taking into account the lifespan of various equipment and weight of equipment placed on the Ukrainian market in previous years, WEEE generation is estimated at more than 1 Mt/year. The share of household WEEE is estimated at 200 thousand t/year (5 kg/year per inhabitant), which is slightly lower than that in other eastern European countries. Computers and electronics hold almost half of household WEEE. WEEE collection rate varies from 0.6% (household devices) to 10.4% (batteries), depending on the waste category. This is much lower than that in the EU. Based on the findings from this paper, one can conclude that the lack of WEEE accounting in the household and commercial sectors of Ukraine creates a significant underestimation of WEEE flows in official data.
Exploring our Open Educational Practices in Support of Excellence in Graduate Education: A Collaborative Autoethnography
Authors: Walsh Pamela , Ives Cindy , Perry Beth
Published: November 2023

This paper presents the findings of our exploration of our open educational practices (OEP) with graduate students. As reflective practitioners, we used a self-study methodology and collaborative autoethnographic methods to interrogate our open approaches to teaching and supervision. We draw on our developing competencies to support the wisdom, critical thinking, resilience, and adaptability of our graduate students. The article extends preliminary findings about graduate education and open practices in relation to and emerging from earlier work (Ives et al., 2022), which committed us to further exploration of our practices. Using our definition of OEP which expands on the work of several open scholars, we report new findings from our in-depth collaborative analysis of data collected over two years. We found a gap in the literature examining the use of OEP with graduate students. Findings include OEP and their alignment with our values and competencies, as well as OEP within our teaching, course design, and graduate supervisory practices. We offer insights into the outcomes of our practices for students and ourselves, and ways we can improve.
Fundamentación del mal y su relación con los procesos de pensamiento, enfermedad y práctica de la medicina
Authors: Ávila Morales Juan Carlos
Published: November 2023

La pregunta por el origen del mal se enmarca en el umbral del encuentro entre lo moral,lo teológico y lo filosófico, aunque más tarde se buscó, en la modernidad, alcanzar una plena separación entre el discurso de la teología y el de la filosofía, y más recientemente, de la bioética. Este artículo aborda la conceptualización del mal y su presencia en el pensamiento moderno a partir de la teodicea de Leibniz, la teoría de Kant y el mal según Nietzsche, así como el enfoque de la radicalización y banalidad del mal desde la perspectiva de Hannah Arendt. De igual manera, se contemplan las formas de entender el mal (instrumental, demoníaco, idealista, estúpido, egoísta y como placer sádico) y se busca establecer su relación con la práctica médica, aclarando la complejidad de tal relación. Se hizo una búsqueda sistemática de información y por medio del análisis bioético y hermenéutico es posible concluir que el concepto del mal ha sido asumido desde lo teológico (con relación al pecado), desde lo moral (Kant) y desde lo político (Arendt), aparece relacionado con el acto y la acción que confluye en una resultante dada por el daño al paciente. El análisis de las vivencias ante la maleficencia de los pacientes y el personal de salud, constituye un insumo importante para el establecimiento de nuevas líneas de investigación.
Financial statement, geographic proximity, and readability footnotes: The moderating effect of the audit fee
Authors: Harymawan Iman , Cahyono Suham , Nasih Mohammad , Kamaruddin Khairul Anuar
Published: November 2023

The paper aims to investigate the relationship between geographic proximity and the readability of financial statement footnotes, which are important sources of information for stakeholders before making decisions about the firm. Our study focuses on examining the impact of distance and audit fees on the dynamics of auditor-client relationships when it comes to generating or evaluating complex financial statement footnotes. The sample for this study consists of 1,117 firm-year observations from firms listed on the Indonesia Stock Exchange (IDX) from 2018-2020. We employ fixed-effect regression and selection bias testing to ensure the robustness of the results. The authors find that geographic proximity between auditors and clients has an impact on the readability of financial statement footnotes, particularly when the distance between the client and auditor is closer, which may make it more challenging to read financial statement footnotes. Additionally, the interaction between audit fees and geographic proximity can make it easier to read financial statement footnotes. Our findings suggest that closer geographic proximity does not provide information advantages regarding hard-to-read financial statement footnotes, and these results are robust to several endogeneity and robustness tests. Our paper contributes to filling the gap between the auditor-client relationship in hard-to-read financial statement footnotes, which are measured by geographic proximity and audit fees, and how auditors and clients can work best in auditing.

A Modest Contribution to the Riemann Hypothesis Using the Poincaré Index
Authors: Oliveira Hime
Published: November 2023

This work uses a new approach to investigate the Riemann hypothesis, drawing conclusions about its trueness. It is based on the more general method presented in a very recent publication, by the same author, showing in detail how to approach that very well-known and interesting problem. This is achieved by means of the theory of dynamical systems (Poincaré index associated to equilibria of 2-dimensional systems) and the study of the zeros of the Dirichlet eta function, defined by a Dirichlet series. By using the well-known fact that the zeros of the eta function include all zeros of the Riemann zeta function in the (open) critical strip, excluded the critical line, (0,1/2) ∪ (1/2,1) × (−∞,∞), the development proceeds using only the eta function. In addition, the open and simply connected region (1/2,1) × (0,∞) is used along the text, taking into account the symmetries of zeros of the functions under analysis in the critical strip. The basic line of proof is to find the mathematical expression for the Poincaré index of the vector field associated to the eta function, assuming the existence of a zero of the eta function outside the critical line (in (1/2,1) × (0,∞)), and investigating the resulting unfoldings. Eventually, an inconsistency occurs and the proof ends by contradiction.
Historical Journey of the Fast Fourier Transform –From Enlightenment Europe via Bletchley Park to the Modern World
Authors: Jones Keith
Published: November 2023

The emergence of the semiconductor industry in the early 1960s resulted in a significant stage in the evolution of computing when large computational problems, as typified by the application of the discrete Fourier transform (DFT) to the task of spectrum estimation, could suddenly, with the availability of suitable algorithms, be solved in close to real time fashion. This paper provides a brief and meandering account of the history of the DFT’s various solutions, referred to generically as the fast Fourier transform (FFT), the algorithm being chosen for its mathematical elegance, practical significance and ever‑increasing range of applications. We touch upon a few of the most striking personalities, places and events that were encountered along the way and look, in particular, at the recent British contribution to the journey.

Modern advanced logging suite and wireline formation tester (WFT) were used for prompt and cost-effective hydrocarbon reserves evaluation for well, drilled through multi-layer clastic formations on unexplored block of the oilfield in West Kazakhstan. Based on acquired comprehensive open-hole wireline logging data and data interpretation results, cased-hole well testing program was severely minimized.

Described in this work appraisal well was drilled thru 16 hydrocarbon-bearing clastic formations of Jurassic and Triassic age deposits. Employed logging suite included quad-combo and nuclear magnetic resonance (NMR) tool for accurate evaluation of required petrophysical properties. Quick-look log data interpretation allowed to derive formations properties and their saturation profiles, preliminary delineate several fluid contact levels, as well as prepare optimized formation testing program. WFT was used to measure formation pressure and fluid mobility, as well as to confirm or clarify formation saturation and fluid contacts, capture representative samples of reservoir oil and gas.

Current case study demonstrates cost-effective approach of obtaining all the required information for quick estimation of hydrocarbons geological reserves for multi-layer clastic formations. Although large number of reservoirs were confidently characterized, described in this work single well formations evaluation, and testing in open hole took less than two weeks.

After setting casing, five out of sixteen productive intervals were perforated and tested, whereafter well was turned into production. Since conventional cased hole testing was performed only for reservoirs, which were required prove of commercial flow, entire well reservoirs testing program was drastically reduced. Described study demonstrates modern and cost-effective way of comprehensive evaluation of hydrocarbon deposits for multi-layer clastic formations of fluvial origin.

Published: November 2023

Active petrophysical geosteering in reservoir formations has become a very promising practice and commonplace to improve express formation evaluation and maximize hydrocarbon production from reservoirs. The present study showcases the effectiveness of utilizing artificial intelligence (AI) framework to process resistivity logging while drilling (LWD) data for the purpose of real-time optimizing well trajectories and maximizing hydrocarbon production in pay zones during drilling horizontal section.

We introduce a novel framework that automatically adjusts planned well trajectories during horizontal drilling. The framework takes the planned wellbore trajectory, reservoir model porosity, and ultra-deep resistivity LWD data as input. Hydrocarbon saturation volume is then calculated using the Archie equation. Subsequently, optimization algorithms correct the planned trajectory to maximize wellbore production using hydrocarbon saturation volume. The framework delivers an optimal wellbore trajectory performing real-time formation evaluation, guiding the drill bit through highly saturated pay zones.

The proposed framework was tested on a 2D synthetic dataset using various optimization algorithms, including reinforcement learning algorithms for continuous action spaces (PPO, DDPG, TwinDDPG) and Q-learning and evolutionary algorithms. The evolutionary group of optimization algorithms achieved the highest efficiency with baseline hyperparameter settings, improving cumulative oil saturation per drilled meter by up to 32.5%. Reinforcement learning algorithms needs to be further explored because they have promising results but still high computational complexity. The evolutionary algorithm was then verified on a 3D Groningen field dataset, determining optimal hyperparameters such as differential evolution strategy, population size, mutational constant, and maximum number of iterations. The framework improved cumulative oil saturation per drilled meter by up to 6%, significantly increasing the average number of penetrated hydrocarbon-saturated pay zones along the drilling path.

The developed AI-based framework presents an innovative approach for real-time automatic correction of well drilling trajectories, maximizing well productivity. This method can significantly aid in the interpretation and optimization of decision-making related to geosteering.
Real-Time Ultra-Deep Azimuthal Resistivity Inversion Helps to Maximize Asset Value in West Kuwait by Locating Uneven Oil-Water Contact

The Burgan sandstone reservoir in the Minagish field of Kuwait is a complex depositional sequence that makes targeting Upper Burgan sands unpredictable due to channeling limiting the reservoir exposure. The area is complicated further by oil-water contact (OWC) uncertainty due to the long history of oil production. The objective of the well was real-time OWC mapping to provide reservoir insight, maximize pay zone exposure and extend the well life through optimizing the completion and production regime.

Recent production pulsed-neutron capture (PNC) logging in an offset well showed watering in the Upper Burgan reservoir. This might indicate a change in the level of the OWC or water coning. Utilization of an ultra-deep azimuthal resistivity (UDAR) mapping service was planned to help locate the OWC below the well trajectory and simultaneously identify and track the desired target sandstone sequence. UDAR has proven its capability to map reservoir boundaries and the OWC in real time, during drilling, earlier than with traditional methods. This facilitates real-time geosteering to drill the well in a single run in the productive zone.

The wellbore was placed in the desired zone by using UDAR real-time 1D inversion services. While drilling, it was discovered that the OWC was at uneven depths compared to what was expected. The reservoir management team obtained important information to update the oilfield development. UDAR services helped to increase reservoir exposure of the well in the Burgan sand of the Minagish oilfield and enhanced the understanding of the sand deposition structure. It was evident that PNC results in the producing offset well do not represent the OWC level throughout the field; instead, localized measurements may be affected by water coning in that specific area. This information led to a change in the field development strategy.

The UDAR real-time 1D inversion enabled optimization of the completion design and perforation intervals, and the understanding of the reservoir potential has been improved. The accurate OWC level evaluation will allow to place more production wells in this location.

Published: November 2023

Modern well planning requires extensive collaboration from multiple domains to design and execute increasingly complex wells. The iterative process requires many specialists and their respective engineering tools, to collaborate in the pursuit of an optimal design for a given well objective. The growth of these specialisms has, in many cases, led to a fragmented landscape that hinders efficiency, coherency and comprehensive risk assessment.

This paper highlights the intricate interactions between sub-domains in well planning, emphasizing the need for a more holistic approach. It continues to introduce a new transformative solution that enables engineers to streamline design iterations, seamlessly collaborate and focus on a broad range of design concepts. Central to this, is an interconnected framework that synchronizes all well design elements and their corresponding operational activities. By introducing key concepts like the "effective wellbore geometry " and "automated engineering analysis " we aim to demonstrate how this sophisticated infrastructure can automatically generate engineering simulations, to provide instant design validation to end users. The holistic, cross-dominant nature of these validations is unprecedented and opens the door to a true step change in planning efficiency and quality.

The paper later identifies some challenges and solutions associated with user collaboration in a cloud native application; striking a balance between freedom to experiment and seamless data sharing with team members. Exploring collaboration models further, concepts such as multi-plan comparison and advanced sensitivity analyses are introduced and described in detail.

Lastly, the technology and concepts that enable the generation and delivery of an "automated drilling program " are highlighted. This notable innovation promises significant potential time saving and improvements to the coherency of documentation typically generated as the culmination of the planning effort.

Subsurface hazards assessment (SSHA) is an essential part of the well planning stage. Successful well execution depends on reducing geological uncertainties associated with hazards and it might prevent unexpected geological non-productive time (GNPT). Ultimately, SSHA can prevent possible catastrophic wellbore failure and loss of control in the drilling operation. The Pre-Caspian basin with its three megacomplexes has different geological hazards and requires unique drilling practices. Hazard mitigation plan can be developed both during well maturation and execution stages by acting accordingly. The approach should incorporate integrated analysis of geological, geophysical, and drilling data. Detailed SSHA and mitigation plan development are valuable constituents and basements for planning safe and cost-effective execution actions. The GNPT incurred due to insufficient recognition of geological uncertainties and underestimation of hazards can cost extra capital up to 30% of the total well execution expenditure. In addition, detailed SSHA is critical to deliver wells as designed ensuring reservoir penetration, formation evaluation and completion installation objectives are achieved fully, and future production is not compromised.
