Published: January 2025

ABSTRACT:
This study presents a comprehensive geomechanical modeling of the naturally fractured Cambrian reservoirs of the Hassi D'Zabat field, Algeria to assess the in-situ stress state and critically stressed fractures. The Cambrian reservoir exhibits vertical to sub-vertical open to partially open fractures, as interpreted from the cores as well as the image log. A cumulative of 41 m of ‘B-quality’ breakouts was interpreted from the acoustic image log indicating a mean SHMax azimuth of N118˚E. Based on the breakout occurrence, SHMax was constrained following the frictional faulting mechanism. The inferred in-situ stress magnitudes (SHMax &gt; Sv &gt; Shmin) indicate a strike-slip tectonic regime in the study area. The practical injection threshold has been inferred as 1850 psi to ensure caprock integrity. The onset of slip on the optimally oriented vertical fractures is estimated to occur at 150 psi of fluid injection in the Cambrian reservoirs. Within the practical injection window, the stress-based model indicates 41 out of 136 steeply dipping fractures becoming critically stressed and therefore experiencing shear slippage.

1. INTRODUCTION
Geomechanics plays a critical role in optimizing the drilling trajectory, fluid injection, and production enhancement (Almalikee and Sen, 2021, 2022; Leila et al., 2021; Farouk et al., 2022; Sen et al., 2024a-c). It has critical implications for naturally fractured reservoirs. When the shear stress to effective normal stress ratio acting on a weak plane (fractures or faults) exceeds the sliding friction of that plane, the probability of shear failure occurrence becomes high, and the fracture is considered to be critically stressed. This study focuses on the prolific Cambro-Ordovician reservoir interval of the Hassi D’Zabat (HDZ), located in the Central Algerian Sahara. The reservoirs are naturally fractured. Waterflood (i.e., water injection) is commonly practiced in these reservoirs at the very early stage of production, to maintain aquifer pressure support. The primary objective of this study was to understand the interplay between natural fractures and in-situ stresses by geomechanical modeling and assess critically stressed fractures during any fluid injection.
Data-Driven Surrogate Models for Bearing Capacity of Spatially Random Soils

Published: January 2025

ABSTRACT:
Soil properties exhibit inherent spatial variability, which can significantly affect the bearing capacity of foundations. This study conducted two-dimensional stochastic simulations of the bearing capacity of shallow foundations on spatially varying soils, utilizing random field theory and smoothed finite-element limit analysis. Despite the use of low-order elements in the numerical analysis, the node-based smoothed finite element method provides highly accurate bearing capacity estimates through kinematic limit analysis. However, running thousands of stochastic simulations to obtain reliable statistical results of bearing capacity can be computationally expensive and time-consuming. Previous studies have demonstrated that employing data-intelligent surrogate models can effectively eliminate computational bottlenecks while maintaining high-quality numerical results for collapse loads. The motivation of this study is to build deep learning-based surrogate models to overcome computational bottlenecks, leveraging machine learning algorithms inspired by the structure and function of the brain. It is shown that the accuracy of data-intelligent surrogate models in these predictions is improved by using various Kernel functions in Gaussian-based surrogate models.

1. INTRODUCTION
Bearing capacity has been estimated using traditionally deterministic analyses, where only average soil properties are considered in the simulations. However, soil exhibits considerable spatial variability due to complex sediment deposition processes (Phoon and Kulhawy, 1999). Ignoring this variability in deterministic calculations can significantly underestimate bearing capacity (Griffiths and Fenton, 2001; Chen et al., 2022, 2023). To overcome this issue, researchers (Griffiths and Fenton, 2001; Griffiths et al., 2002; Fenton and Griffiths, 2002, 2003, 2005; Cheng et al., 2024) applied random field theory to incorporate spatial variability of soil and developed the random finite element method (RFEM) to estimate the probability distribution of bearing capacity.
A typical RFEM analysis uses a Monte Carlo method, where random field samples of soil properties are generated and integrated into finite element (FE) models. Numerous random FE simulations are required to obtain statistical estimates of bearing capacity. However, this method is computationally demanding because it requires many samples for accurate statistical results. To address this issue, surrogate models, such as those utilizing machine learning techniques, can replace the time-consuming FE simulations. This updated method involves generating random field samples, running a limited number of FE simulations, training machine learning models, and then performing statistical analysis using the trained models.
Maximizing Production Efficiency: Geomechanical Assessment for Infill Well Optimization in Waterflood Developments in Crescent-Shaped Rim Structure Field, South of Oman

ABSTRACT:
PDO's project portfolio includes numerous active waterflood developments, including a crescent-shaped rim structure field operating under Peripheral Waterflood with Flank Injection (PWRI). To enhance production rates, the proposed development plan involves infill drilling with reduced spacing between injectors and producers. However, this closer spacing could lead to potential risks associated with waterflood-induced fracturing, resulting in reduced sweep efficiency.
In order to optimize the infill well spacing and minimize the risk of injector-producer short-circuiting and out-of-zone injection, a geomechanical assessment was conducted. Understanding formation fracture pressure and in-situ stress orientations was crucial for determining induced fracture directions relative to well azimuths. Given the crescent shape of the field and the outward orientation of most wells towards the flank direction, well azimuths varied from east to west. Injector wells were categorized into three groups based on the location: East, Crest, and West, with varying azimuth orientations.
To determine stress orientation, borehole image (BHI) data from analog fields were analyzed to ascertain the expected orientation of maximum horizontal stress (SHmax). Detailed analyses using modified Hall's plot approach were conducted using injection pressure-rate data from 14 injectors to characterize current operating injection conditions (matrix vs. fractured). Field data from fracture pressure tests and analysis were interpreted to determine formation fracture pressure. Additionally, parameters such as injectivity, productivity, and depth of perforation relative to the Oil-Water Contact (OWC) were investigated to understand injection performance. Using these inputs, a calibrated PWRI frac model was developed to analyze fracture growth over time and pre dict fracture dimensions.
The study revealed that producer wells in the East group were at higher risk of potential water breakthrough from induced fractures from injectors, as they were along the intersection path of propagating fracture directions. Modeling results showed that un der an injection rate of 2000 m3/day over 25 years, the maximum predicted fracture (half) length reached approximately 350 m (i.e., the field's end of life). Producer wells in the West group had a lower risk due to their well directions being approximately parallel to the direction of fracture propagation, while wells in the crest area were assessed to have a medium risk.
These findings demonstrated that using a constant spacing for the entire field was not an optimal solution. Minimizing the risk of early water breakthrough and short-circuiting was essential in determining spacing. The study's results provided valuable guidance on operational injection pressures for waterflood optimization and improved recovery efficiency.

Background: Hyperuricemia, defined as elevated serum uric acid levels (>6 mg/dL in women, >7 mg/dL in men), affects approximately 38 million Americans, with rising global prevalence due to Westernized diets and lifestyles. While often asymptomatic, hyperuricemia is associated with gout, nephrolithiasis, and systemic conditions like hypertension, metabolic syndrome, and cardiovascular disease. It results from increased uric acid production, decreased renal excretion, or a combination of both. Aim: This article provides a comprehensive overview of hyperuricemia, focusing on its etiology, pathophysiology, clinical manifestations, and management strategies, with an emphasis on gout and nephrolithiasis. Methods: The review synthesizes current literature on hyperuricemia, including its epidemiology, mechanisms, diagnostic evaluation, and treatment options. It also examines the role of dietary, genetic, and pharmacological factors in disease progression and management. Results: Hyperuricemia is primarily managed through lifestyle modifications and pharmacological interventions. First-line treatment includes xanthine oxidase inhibitors like allopurinol, while uricosuric agents and recombinant uricase drugs are reserved for refractory cases. Dietary education, particularly a low-purine, low-fructose diet, is crucial for prevention and management. Complications such as gout, nephrolithiasis, and chronic kidney disease require tailored interventions, including urate-lowering therapy and urinary alkalinization. Conclusion: Hyperuricemia is a multifactorial condition with significant implications for gout, nephrolithiasis, and systemic health. Effective management requires a combination of lifestyle changes, pharmacological therapy, and patient education. While asymptomatic hyperuricemia often does not require treatment, symptomatic cases necessitate individualized care to prevent complications and improve quality of life.

Д.А. Крайнов (1904–1998) – известный советский и российский археолог, более 40 лет посвятил археологическому изучению древнейшего прошлого Верхнего Поволжья. Работы его в этом регионе начались ещё до Великой Отечественной войны. Однако наиболее интенсивные исследования приходятся на послевоенное время, особенно 1960–1980-е годы. Основные заслуги его связаны прежде всего с раскопками 28 могильников фатьяновской культуры эпохи бронзы. На материалах раскопок он создал целостное представление о происхождении, хронологии, материальной и духовной культуре, хозяйстве и социальной структуре носителей фатьяновской культуры. В начале 1970-х годов Д.А. Крайнов сделал своё самое значительное открытие в археологии неолита – выделил верхневолжскую ранненеолитическую культуру. Это открытие заставило пересмотреть происхождение, хронологию и последовательность развития неолитических культур лесной зоны Европейской части России.
D.A. Krainov (1904–1998) was a famous Soviet and Russian archaeologist who devoted more than 40 years to the archaeological study of the ancient past of the Upper Volga region. His work in this region began even before the Great Patriotic War. However, the most intensive research occurred in the post-war period, especially the 1960s– 1980s. His main achievements are connected, first of all, with the excavations of 28 burial grounds of the Fatyanovo culture of the Bronze Age. Based on the materials of the excavations, he created a holistic view of the origin, chronology, material and spiritual culture, economy and social structure of the bearers of the Fatyanovo culture. In the early 1970s, D.A. Krainov made his most significant discovery in Neolithic archaeology – he identified the Upper Volga Early Neolithic Culture. This discovery forced us to reconsider the origin, chronology and sequence of development of the Neolithic cultures of the forest zone of the European part of Russia.

ImportancePolice shootings can cause serious acute injury, and knowledge of subsequent health outcomes may inform interventions to improve care.ObjectiveTo analyze long-term health care costs among survivors of police shootings compared with those surviving nonfirearm police enforcement injuries using a retrospective design.Design, Setting, and ParticipantsThis population-based cohort analysis identified adults (age ≥16 years) who were injured by police and required emergency medical care between April 1, 2002, and March 31, 2022, in Ontario, Canada.ExposurePolice shootings compared with other mechanisms of injury involving police.Main Outcomes and MeasuresLong-term health care costs determined using a validated costing algorithm. Secondary outcomes included short-term mortality, acute care treatments, and rates of subsequent disability.ResultsOver the study, 13 545 adults were injured from police enforcement (mean [SD] age, 35 [12] years; 11 637 males [86%]). A total of 13 520 individuals survived acute injury, and 8755 had long-term financial data available (88 surviving firearm injury, 8667 surviving nonfirearm injury). Patients surviving firearm injury had 3 times greater health care costs per year (CAD$16 223 vs CAD$5412; mean increase, CAD$9967; 95% CI, 6697-13 237; US $11 982 vs US $3997; mean increase, US $7361; 95% CI, 4946-9776; P &amp;lt; .001). Greater costs after a firearm injury were not explained by baseline costs and primarily reflected increased psychiatric care. Other characteristics associated with increased long-term health care costs included prior mental illness and a substance use diagnosis.Conclusions and RelevanceIn this longitudinal cohort study of long-term health care costs, patients surviving a police shooting had substantial health care costs compared with those injured from other forms of police enforcement. Costs primarily reflected psychiatric care and suggest the need to prioritize early recognition and prevention.

ImportanceAlthough the barriers to dementia care in primary care are well characterized, primary care practitioner (PCP) perspectives could be used to support the design of values-aligned dementia care pathways that strengthen the role of primary care.ObjectiveTo describe PCP perspectives on their role in dementia diagnosis and care.Design, Setting, and ParticipationIn this qualitative study, interviews were conducted with 39 PCPs (medical doctors, nurse practitioners, and doctors of osteopathic medicine) in California between March 2020 and November 2022. Results were analyzed using thematic analysis.Main Outcomes and MeasuresOverarching themes associated with PCP roles in dementia care.ResultsInterviews were conducted with 39 PCPs (25 [64.1%] were female; 16 [41%] were Asian). The majority (36 PCPs [92.3%]) reported that more than half of their patients were insured via MediCal, the California Medicaid program serving low-income individuals. Six themes were identified that convey PCPs’ perspectives on their role in dementia care. These themes focused on (1) their role as first point of contact and in the diagnostic workup; (2) the importance of long-term, trusting relationships with patients; (3) the value of understanding patients’ life contexts; (4) their work to involve and educate families; (5) their activities around coordinating dementia care; and (6) how the care they want to provide may be limited by systems-level constraints.Conclusions and RelevanceIn this qualitative study of PCP perspectives on their role in dementia care, there was alignment between PCP perspectives about the core values of primary care and their work diagnosing and providing care for people living with dementia. The study also identified a mismatch between these values and the health systems infrastructure for dementia care in their practice environment.
