Authors: Zeng Bo , Huang Haoyong , Chen Liqing , Liu Chuxi , Yu Wei , Leines Joseph , Miao Jijun
Published: January 2025

The increasing development of unconventional shale gas reservoirs necessitates more efficient and accurate methods for hydraulic fracture evaluation and reservoir production forecasting. This study introduces an AI-integrated geology-engineering workflow to optimize fracture geometry and production performance using GPU-based supercomputing. The workflow centers around the ZFRAC hydraulic fracture simulator, which employs the boundary element method (BEM) for fracture modeling and integrates XGBoost for calibration with pumping pressure data. A deep shale gas well in the Sichuan Basin, China, was modeled using detailed geomechanical parameters and 28 hydraulic fracturing stages. The fracture geometry was calibrated to reflect the actual reservoir conditions, achieving a 90% accuracy. The calibrated fractures were incorporated into the Embedded Discrete Fracture Model (EDFM) for production simulation and forecasting. The Estimated Ultimate Recovery (EUR) was predicted to be 0.163 billion cubic meters (bcm) over 20 years. The economic evaluation yielded a Net Present Value (NPV) of 27.4 million Chinese Yuan and an Internal Rate of Return (IRR) of +1.96% after 20 years. These results highlight the effectiveness of the workflow in optimizing fracture design and predicting long-term reservoir performance, offering valuable insights for future shale gas developments.

1. INTRODUCTION

In recent years, the development of unconventional oil and gas reservoirs has accelerated, driven by growing energy demand and advancements in extraction technologies. Shale gas reservoirs, particularly in the Sichuan Basin of southwestern China, have become a focal point due to their vast resource potential. The Sichuan Basin is one of the world's most prolific shale gas regions, with significant reserves trapped in tight formations that require enhanced stimulation techniques for optimal extraction (Yong et al., 2019; Zeng et al., 2021; Wu et al., 2023, 2024). Hydraulic fracturing is the primary method used to unlock these resources, but with the increasing number of wells and multi-pad developments, comprehensive evaluation of the fracturing process is essential. These assessments are critical for ensuring optimal performance, maximizing resource recovery, and minimizing operational inefficiencies.

Published: January 2025

To mitigate drilling risks and optimize the economic and efficient utilization of carbonate resources, precise reservoir characterization is essential. However, predicting the distribution of natural fractures and vugs in carbonate reservoirs using seismic and well data is fraught with uncertainty. This arises from challenges such as inadequate well interpretation, poor seismic imaging, and inconsistencies between well and seismic data. This study aims to reduce these uncertainties by calibrating the interpretation of natural fractures and vugs using well log and seismic data. Additionally, a machine learning model is developed to predict the 3D spatial distribution of fractures and vugs in limestone reservoirs. The research focuses on the limestone formations of the H oilfield in the southeastern Mesopotamia Basin of Iraq. Seismic attributes are extracted from inter-well regions based on well locations and tracks from six characteristic wells, and these attributes are classified and calibrated in relation to fractures and vugs. Data balancing techniques are applied, and feature engineering is performed to optimize model performance. An ensemble learning method is then used to establish a nonlinear mapping between the predicted targets (fractures, vugs, matrix) and seismic attributes. Blind well testing is conducted to verify the reliability of the model. The study ultimately provides a 3D prediction of the spatial distribution of fractures and vugs, derived from the established relationships rather than the original properties. The model achieves an average prediction accuracy of 83%. The results show that vugs are primarily distributed in the MA layer, while fractures and vugs are mainly found in the MB layer, and fractures are predominantly located in the MC layer. When planning horizontal wells, the well trajectory should be optimized to reduce the risks of mud loss and wellbore instability, particularly in the MC layer. The model offers detailed information on the distribution of fractures and vugs at different depths and geographical locations, providing crucial guidance for the development of optimal drilling plans and offering both technical and theoretical support for reservoir development strategies.
Four-Dimensional Ultrasonic Caliper While Drilling Enables Advanced Wellbore Evaluation in Slim Hole Size
Authors: Soelem R. , Taher A. , Fouda M.
Published: January 2025

Evaluation of hole conditions is a key measurement for safe drilling and completion operations. Acquiring an accurate hole size measurement has been traditionally performed using wireline mechanical calipers deployed after drilling operations have been completed. This paper demonstrates how logging-while-drilling (LWD) ultrasonic sensors can be used to provide a time-lapse (4D) alternative azimuthal measurement of hole size, enabling data acquisition in different phases of drilling and tripping operations.

LWD ultrasonic caliper measures the travel time and computes the tool's stand-off to the wellbore wall. Acquiring azimuthal data around the wellbore during different logging passes enables acquisition of 4D caliper information. After being calibrated inside casing, the ultrasonic sensor provides azimuthal travel-time images, based on which minimum, maximum, and average hole sizes can be computed.

Data have been acquired in drilling, trip-in, and trip-out modes and compared to wireline-oriented calipers. The data has been evaluated considering time-dependent deterioration, washout, and breakout developments.

Recently introduced LWD slim ultrasonic imaging and caliper tools have multiple transducers and fast sampling rates. The hardware and algorithm design improves the hole size computation and wellbore evaluation. The tools provide a viable alternative to wireline mechanical calipers. While field data showed a good match in competent formations, differences between data acquired in multiple LWD logging passes and wireline mechanical caliper runs have provided 4D caliper information for evaluating time-dependent changes in hole conditions enabling future optimization of well construction.

This paper illustrates the utilization of LWD ultrasonic sensors integrated as part of the drilling assembly to provide a 4D azimuthal measurement of hole size at different times, during drilling and tripping in and out of the hole.

Introduction

Maintaining stable and competent wellbores is essential for safe and successful drilling, logging, and completion of oil and gas wells. Wellbore instabilities can also cause unplanned operational delays and unnecessary costs. Well instability can also increase with an increase in well inclination, leading to higher costs in high-angle well operations. which may negate the benefit of horizontal drilling techniques (Aadony and Looyeh, 2010).
Predictions of Swab/Surge Pressure of Tripping Under Pump Circulation Based on Narrow Slot Geometry
Authors: Tan Zhenlai , Li Xiongrong , Wei Yaoran , Yan Shuang , Yang Tianyu , Feng Yongcun , Wang Guangyu
Published: January 2025

Swab/Surge pressure will increase the risk of wellbore stability such as lost circulation, wellbore collapse, kicks, and even blowouts, particularly in formations with narrow safe mud weight windows. The existing studies for predicting swab/surge pressures only consider pressure variations induced by tripping and hardly consider the effects of pump circulation during tripping. This paper presents a new steady-state model based on narrow slot geometry. The model aims to predict swab/surge pressure during tripping with pump circulation. Meanwhile, to mitigate the impact of fluctuation pressures on wellbore stability, the design of tripping speed, and pump displacement are investigated in this study. Results show pump circulation increases the pressure in the wellbore, partly offsetting swab pressure and increasing surge pressure. The faster the speed of tripping, the higher the fluctuation pressure. This study provides a theoretical foundation for predicting swab/surge pressure, which is of significant practical importance and application value in reducing wellbore instability caused by fluctuation pressure.

1. INTRODUCTION

In deep and ultra-deep drilling, accurately predicting pressure variations in the wellbore is crucial, especially in formation with a narrow safe mud weight windows (Cayeux and Daireaux, 2017; SUN et al., 2024; Wei et al., 2024). Tripping, casing and cementing can generate pressure variations (Balanza et al., 2015). Pressure variations caused by tripping are referred to as fluctuation pressures, which include swab pressure and surge pressure. Swab pressure, which is usually defined as a negative value, reduces the pressure in the wellbore (Mohammad and Davidrajuh, 2022; Meng et al., 2019). Figure 1, excessive swab pressure lowers the wellbore pressure to an unbalanced state, increasing the risk of wellbore collapse. Formation fluids enter the wellbore, potentially leading to a kick and eventually a blowout (Huang et al., 2022; Wei et al., 2022). Conversely, surge pressure, which is usually defined as a positive value, increases the pressure in the wellbore that may be in an overbalanced state. Figure 2, excessive surge pressure can lead to formation fractures or continuous leakage of drilling fluid into the permeable formation, ultimately resulting in lost circulation. Fluctuation pressure is a cause of wellbore instability (Cao et al., 2014; Zhao et al., 2023; Fekete et al., 2015). Therefore, accurate prediction of fluctuation pressure is essential for safe and efficient drilling (He et al., 2016; Ettehadi and Altun, 2018; Erge et al., 2018).

Published: January 2025

The fractures produced by hydraulic fracturing twist and extend in three-dimensional space, often forming complex nonplanar shapes, which makes the transportation law of proppant more complicated. To study the transportation law of proppant in the nonplanar fractures, the morphology of fracture propagation was obtained by phase field method, and a fluid-solid coupling model of proppant transportation in the three-dimensional nonplanar fractures was established. The solution was based on computational fluid dynamics (CFD) and discrete element method (DEM), and the effects of injection rate, sand ratio, proppant density and proppant size on the transportation law were studied. The results show that the nonplanar fractures make the transportation law of proppant more complicated. Increasing the injection rate can avoid sand plugging in the near-well area and increase the sand distribution distance. Low sand ratio can effectively improve the proppant transportation effect. With the decrease of proppant density and size, the sand distribution height decreases. This study clarifies the transportation law of proppant in the nonplanar fractures, which helps to guide the design of proppant pumping parameters during fracturing construction.

1. INTRODUCTION

As oil and gas production gradually moves towards unconventional resources, hydraulic fracturing technology has become an important measure for enhanced oil recovery (Liew et al., 2020). During the hydraulic fracturing process, if the fracture initiation is not in the direction of maximum horizontal principal stress, the fracture may turn from the perforation direction to the direction of maximum horizontal principal stress after expansion, forming a complex nonplanar fracture (Tan et al., 2017). In order to improve the effect of reservoir transformation, proppant needs to be injected into the formation to fill the propped fracture and form a diversion channel for oil and gas production (Liang et al., 2016). If the proppant cannot be effectively laid in the nonplanar fracture, it will have an important impact on the effect of hydraulic fracturing.
Earthquake Classification Using Resnet 50 Model: A Machine Learning Approach
Authors: Kaushik Mahanta K. M.
Published: January 2025

Earthquakes can result in significant loss and damage to life and infrastructure, which requires rapid and accurate detection. Traditional methods often face challenges in classifying earthquake signals from noise especially in seismically active zones. This study explores the application of the ResNet-50 deep-learning convolutional neural network model to classify earthquake signals using seismic waveforms. The model is trained on the Italian earthquake dataset containing 1.2 million three-component traces from approximately 50,000 earthquakes and 130,000 noise traces recorded between 2005 and 2020. ResNet-50 enhances feature representation better gradient flow during backpropagation through residual connections. The Binary Cross Entropy (BCE) loss function and ADAM optimizer is used in this study with spectral analysis aiding to extract frequency features. The model achieves an accuracy ranging from 0.79 to 0.95, with precision and recall between 0.79 to 0.97, demonstrating its effectiveness in accurately identifying seismic events amid background noise. These findings highlight the potential of the ResNet-50 model to enhance earthquake monitoring and early detection systems.

1. INTRODUCTION

One of the most impressive geological phenomena, earthquakes, can have disastrous consequences for life and infrastructure. Earthquakes continue to be among the most erratic natural disasters. A summary of the 20 years’ worth of catastrophes shows 552 earthquakes or 8% of all disasters globally. These earthquakes rank third after storms (2043 events, or 28% of the total) and floods (3254 events, or 44%) (Mavrouli et al., 2023). In addition to intense ground motion and seismic events, secondary effects, primarily landslides and tsunamis, are also blamed for related calamities causing loss of life and damage to infrastructures. Accurate classification of earthquake signals is important in applications of earthquake early warning, monitoring and seismic data processing. This work aims to train a convolutional neural network (CNN) with seismic data to enable it to identify signals as noise or earthquake.

Recent developments in Machine learning have led to complex neural network architectures. These architectures perform exceptionally effectively in pattern recognition tasks. Deep learning algorithms like CNN effectively segment and classify tasks, including image recognition, signal processing, and medical imaging. These algorithms can learn complex patterns and features from the data, making them a great tool to apply to waveform analysis for robust end, efficient earthquake signal detection tasks.
3D Source Rock Characterization, Energy Storage Estimation and Machine-Learning Algorithms for CO2 Sequestration in Depleted Oil Reservoirs for Enhanced Oil Recovery: An Integrated Approach for CO2-EOR
Authors: Fayyaz Najwa
Published: January 2025

The integration of advanced computational techniques with traditional reservoir engineering practices has revolutionized the field of enhanced oil recovery (EOR), particularly in the context of carbon sequestration. This study integrates machine learning (ML) algorithms and 3D visualization techniques to optimize CO2 sequestration and enhanced oil recovery (CO2-EOR) in the depleted Balkasar Oil Field, located in Pakistan's Potwar Basin. The application of ML, including neural networks and decision trees, allowed for the detailed analysis of extensive datasets comprising well logs, seismic surveys, and petrophysical measurements. The algorithms uncovered complex relationships between key reservoir properties, such as porosity, permeability, and hydrocarbon saturation, enabling precise predictions of hydrocarbon-bearing zones and dynamic fluid behaviors. A 3D geomechanical grid was constructed to visualize subsurface heterogeneities, including fault zones and fluid distribution, aiding in the identification of optimal CO2 injection zones. Simulations conducted on this grid revealed a recovery efficiency enhancement exceeding 30%, confirming the potential for significant hydrocarbon recovery. Moreover, pressure monitoring and CO2 plume migration predictions validated the integrity of sequestration, with stable storage observed under varying injection scenarios. The study's findings underscore the transformative potential of integrating advanced computational tools with traditional reservoir engineering methods. For instance, dynamic modeling in the Chorgali and Sakesar formations identified zones with high hydrocarbon retention, ensuring strategic injection planning. The multivariate fitting method demonstrated robust predictions of organic carbon content, essential for assessing the reservoir's remaining hydrocarbon potential.

1. INTRODUCTION

The transition toward sustainable energy practices necessitates innovative strategies that simultaneously address the imperatives of carbon reduction and efficient hydrocarbon recovery. The global energy sector is facing increasing pressure to mitigate climate change while meeting growing energy demands (Earlougher, 1977).

This process involves injecting CO2 into depleted oil fields, where it reduces oil viscosity, improving its flow to production wells (Bourdet, 2002). ML models, such as neural networks and decision trees, can uncover hidden patterns in the data, improving the accuracy of reservoir predictions and optimizing CO2-EOR strategies (Manrique et al., 2007).

Published: January 2025

This study presents a geomechanically-informed hydraulic fracture modeling workflow applied to two horizontal wells in a deep coalbed methane (CBM) pad. Key rock mechanical properties, including Young's Modulus, Poisson's Ratio, and in-situ stresses, were incorporated into the hydraulic fracture model to capture reservoir heterogeneity. A 3D Discrete Fracture Network (DFN) was integrated to account for natural fractures. The model was calibrated using observed pumping pressures, with adjustments to perforation parameters to match the simulated values. The calibrated hydraulic fracture geometry for Well-1 showed a half-length of 120.39 m and a height of 12.40 m, while Well-2 exhibited a half-length of 137.11 m and a height of 13.24 m. The effective fracture lengths were reduced to 95.10 m and 108.32 m, respectively, due to production-induced stress and proppant embedment. The Embedded Discrete Fracture Model (EDFM) was used to couple the fracture model with the reservoir simulation for long-term production forecasts. Estimated Ultimate Recovery (EUR) over a 20-year period was predicted to be 3.75 × 107 m3 for Well-1 and 5.16 × 107 m3 for Well-2. Drained Rock Volume (DRV) analysis provided insights into reservoir depletion and optimized well spacing strategies.

1. INTRODUCTION

China's deep coalbed methane (CBM) reserves represent a substantial energy resource with significant potential to meet the country's growing demand for clean energy. As of 2023, annual CBM production reached 11.7 billion cubic meters, highlighting the resource's importance in the national energy mix. Recent exploration breakthroughs in the East Erdos Basin have revealed the vast untapped potential of deep CBM reservoirs, positioning this unconventional resource for accelerated development (Ma et al., 2024; Jia et al., 2024). However, deep CBM reservoirs differ markedly from conventional shale or tight gas reservoirs, posing unique geological and geomechanical challenges (Liu et al., 2024). These differences necessitate the use of specialized hydraulic fracture simulation techniques to optimize production strategies and address the complexities inherent in these reservoirs (Wang et al., 2024).
Geomechanics of Tectonic Stress Path Constraints and Outcrop Deformation Analysis of Naturally Fractured Rocks: A Case Study Along Main Boundary Thrust (MBT) and Nathia Gali Thrust (NGT), NW-Himalayas, Pakistan

Published: January 2025

Fractures are significant deformation-induced structural structures that appear in rocks under brittle conditions. Establishing a link between structural evolution and paleo stress orientations is thus required to provide comprehensive tectonic models for the studied region. The research region is located in the Lesser Himalaya (LH), which is bordered to the north by the Main Central Thrust (MCT) and south by the Main Boundary Thrust (MBT). The purpose of this work is to evaluate the fracture pattern in the rocks along the Main Boundary Thrust (MBT, NW Himalaya, Pakistan) and undertake paleo stress analysis. Fifty distinct circle inventories were made in the Beld, and 550 fracture orientations were seen and documented. The Win-Tensor application is then used to evaluate the fracture data for paleo-stress inversion. It is an interactive computer application for fracture analysis and paleo stress reconstruction that is based on the Right Dihedron Method. The findings show a compressive tectonic regime with r1 trending NNW–SSE. The Main Boundary Thrust (MBT) is thought to develop almost perpendicular to the direction of the highest primary stress orientation.

1. INTRODUCTION

The geomechanics and mechanical properties of near-surface rock materials are significantly influenced by discontinuities, such as veins, fault frictional sliding, seismic characteristics, permeability, and fluid flow. Tectonic activity in the Earth's crust creates structural discontinuities such as faults, fractures, and joints. This work hypothesizes that the stress route influences rock deformation and failure, and establishing a link between structural evolution and paleo-stress orientations is critical for developing complete tectonic models (Allen et al., 1993). Paleo-stress studies are predicated on the idea that the direction of the highest shear stress should be the direction of the slide along the fault plane as shown in Figure 1. The stress ratio (R)= ((r2r3)/(r1r3)) and the three stress levels (highest (r1), intermediate (r2), and minimum (r3)) make up the outcome. There is an extensional stress regime (Normal Faults) if r1 is vertical and r2 and r3 are horizontal; a transpressional regime (strike-slip faults) if r2 is vertical and r1 and r3 act horizontally; and reverse/thrust faulting if r3 is vertical and r1 and r2 are horizontal (Anderson, 1905). Finding a connection between the paleo stress Beds and the later formation of the Himalayan MBT will enable us to ascertain the kinematics of the fractures associated with MBT and NDT, NW Himalayas, Pakistan. (Najwa et al., 2023).
A Young Man, an Old Ritual, and Maya Ethnoscience
Authors: Cook Della Collins
Published: January 2025

Burial 163 from Postclassic Chau Hiix, Belize, is mentioned in several publications, but has not been fully described. This tightly flexed, prone young man had unusual grave goods: a deer bone flute, an olivella shell anklet, a snake vertebra belt, and ornaments made from the pharyngeal dentaries of two species of parrotfish. These items permit reconstruction of a costume reflecting that of the snake dancer and musicians on the famous Classic vase from Altar de Sacrificios. The persistence of this costume across time and space shows that elements of the Wayob ritual survived the Maya Collapse. The variety of animals used in its manufacture points to a symbol system more complicated than nagualism or totemism. His robust good health stretches concepts of distinction among Maya elites and commoners.

Published: January 2025

In the limestone-shaded recesses of the Caves Branch Rockshelter (CBR) of Central Belize, bioarchaeologists uncovered the fragmented, fragile skeletal remains of an older female (Burial 99). The modified shape of her cranium, molded and elongated when she was a young child, indicated that she likely died during the Late Classic (AD 699–900). Were she buried deep within a cave during this period, she would not have stood out to the bioarchaeologists, as caves are well known as repositories for modified individuals. The woman’s body was instead interred among the commingled remains of hundreds of individuals of all ages and sexes, without shaped crania, who were buried during the Late Preclassic/Protoclassic (300 BC–AD 300). This chapter explores both how Burial 99’s lived experience was embodied during life and how her placement in the Rockshelter may reflect the complexities of the Maya mortuary landscape through time.
Tying the Knot between the Maya Ruler Janaab’ Pakal and Lady Tz’akab’ Ajaw
Authors: Tiesler Vera , García Erik Velásquez
Published: January 2025

Ancient Maya dynasties have centralized historical information by appearing in iconography and by being the main and preferred subjects of epigraphic representation. In recent decades, body-centered recreations of ancient dynastic histories have also attracted Mayanist scholarship. Especially during the last decade, bioarchaeology, in tandem with a growing host of archaeometric analyses, has become a powerful analytical resource in the detailed, objective and unbiased reconstruction of the life and death of well-known historical figures. This chapter shows and debates the power of this analytical resource through a combined osteobiography of a married couple of Maya sovereigns from the Classic Maya city of Palenque, Mexico. Janaab’ Pakal was buried in AD 683 inside a temple, the construction of which he had commissioned many years prior to his demise. His consort of many years, Lady Tz’akab’ Ajaw, better known as the “Red Queen,” was in all likelihood buried in AD 672 adjacent to her husband’s funerary mausoleum to be.

Published: January 2025

Plant resistance to extreme environmental conditions is a complex of features that depends on the magnitude and exposure duration to high temperatures and drought both in the structural (anatomical and morphological) and functional (physiological and biochemical) terms, as well as on the implementation degree of the genotype individual genetic program. In this regard, the plant resistance study to unfavorable environmental factors, in particular drought, is one of the most important problems of agricultural production and is of great practical and theoretical importance. By the method of hybridization based on the use of samples from the collection of the genus Fagopyrum Mill, a valuable source material was obtained on the drought resistance basis with high yielding and improved technological indicators of grain quality adapted to Podillia conditions. 13 varieties were selected, direct and reciprocal saturating crosses were carried out; a comparison of the new source material with the standard variety Victoria and the original parental forms was carried out; drought tolerance assessment was carried out; on the basis of a comparative assessment, economically important indicatorsof buckwheat hybrids grain were established: the growing season, productivity and technological indicators of grain quality. The express-assessment efficiency of buckwheat breeding material on the basis ofdrought resistance by germination of seeds in osmotic solutions with a sucrose concentration of 13.9% has been established. The varieties Skorostyhla 86, Smuglianka, Kazanka, Alenushka, and Veselka are donors for the new source material on the basis of drought resistance. The hybrids created on their basis have a clear character of the manifestation of this trait under various assessment methods. It was determined that the higher drought resistance in comparison with the parental forms and the standard variety Victoria have hybrid combinations Kazanka x Smuhlianka (47%), (Kazanka x Smuglianka) x Smuglianka (47.3%) (Skorostyhla 86 x Solianska) x Solianska (64 8 %) (Alyonushka x Veselka) x Veselka (81.7%). These hybrids of buckwheat have a 5-12 days shorter growing season, higher drought resistance (by 35.4-81.7%), higher by 0.2-0.36 t / ha grain yield compared to the standard variety Victoria. The grain of these numbers is characterized by high technological properties; for processing into cereals, its chemical composition and food safety indicators comply with regulatory requirements..
