Published: January 2025

Multi-stage hydraulic fracturing is a crucial technology in the Sichuan Basin, China owing to its potential for natural gas production. However, reservoir characterization in a complex geological environment whose architecture is dominated by small- and large-scale fracture corridors poses significant challenges to an effective economic field development. Multistage fracturing uniformity indices rely on an optimal fluid distribution in every stage, which can be hampered by geological structures that serve as leakage sites in the reservoir. Recent field developments in the Sichuan Basin's shale reservoirs have motivated to characterize natural fracture properties and hydraulic fracture geometry based on geophysical data. This work employs an innovative method to extract three-dimensional (3D) natural fractures in fracture corridors from ant tracking and maximum curvature seismic features. The fracture corridors are directly included in reservoir simulation workflows. The results can be readily used for hydraulic fracturing completion optimization in unconventional reservoirs.

1. INTRODUCTION

Gas production in Sichuan basin has made significant progresses in the last few years by adopting well-known technologies such as multistage fracturing. However, geological complexities still limit optimal deployment of stimulation treatments. During hydraulic fracturing propagation, numerous fracture corridors and pad-scale faults are encountered, which poses challenges to a uniform fluid distribution inside perforation clusters. Fluid leaking in such geological complexities reduce the efficiency of the stimulation treatment, leaving poorly stimulated stages. For those reasons, operators have put significant efforts in geological characterization with the hopes to efficiently model potential leakage sites and find strategies to avoid low performance. Literature shows work on automatic fault detection and fracture corridor characterization using seismic data. Fault detection has progressed in the last few years, resulting in accurate representations of such features (Hu et al., 2014; Fang et al., 2017). Fracture corridor characterization, however, is often simplified using faults to describe them (Astratti et al., 2010) or using upscaling methods in reservoir models (Ahmed et al., 2010; Zhang and Koutsabeloulis, 2010). The accurate modeling of both faults and fracture corridors are essential to optimize gas production in the Sichuan basin.

Published: January 2025

Casing deformation in shale gas wells is a significant challenge that compromises wellbore integrity and reduces production efficiency, particularly in complex geological settings such as the Sichuan Basin, China. This study focuses on mitigating casing deformation risks in a typical shale gas pad consisting of four horizontal wells. A detailed geomechanical analysis was conducted, examining stress distribution and rock brittleness. A natural fracture model was developed, identifying four groups of fractures with lateral scales ranging from tens of meters to kilometers. A total of 31 stages with casing deformation risks were identified: 6 stages in Well-1, 6 in Well-2, 10 in Well-3, and 9 in Well-4. Three mitigation methods were proposed: optimizing stage and cluster design to avoid high-risk fracture zones (e.g., bypassing a 130-meter high-risk section in Well-2), reducing sand intensity to below 3 tons per meter in 2/3 of high-risk stages, and adjusting the fracturing sequence to prioritize high-risk stages. These methods effectively enhance wellbore integrity and optimize hydraulic fracturing operations.

1. INTRODUCTION

Casing deformation during hydraulic fracturing presents a significant challenge in the development of shale gas reservoirs, especially in geologically complex regions such as the Sichuan Basin, China (Zeng et al., 2021; Liu et al., 2023; Han et al., 2023; Wu et al., 2024; Uribe-Patino et al., 2024). As global demand for shale gas rises, maintaining the integrity of wellbore casings becomes increasingly crucial to ensuring safe and productive gas extraction. Casing deformation, which results from excessive stress and strain on the steel casing, can compromise wellbore integrity, leading to reduced production, costly repairs, and even well abandonment in severe cases. The presence of natural fractures, varying stress conditions, and faults in the reservoir often exacerbate deformation, making it essential to understand these mechanisms and develop effective mitigation strategies to optimize hydraulic fracturing and ensure the long-term viability of shale gas wells.
Assessing Subsea Well Architecture Impact on A-Annulus Behaviour: Case Study from Ichthys Gas Field, Australia

Published: January 2025

In response to higher reservoir temperatures in the Jurassic Plover formations, significant modifications were made to well architecture and tree hardware to endure temperatures up to 165°C. The new design featured 26" and 36" casings with dual cement return ports. While the lower ports on the "D" annulus were sealed during cementing, the upper ports on the ‘C’ annulus remained open. Production from the Plover wells revealed regular fluctuations in A-annulus pressure, raising concerns about well integrity. A multidisciplinary investigation identified a strong correlation between A-annulus pressure variations, tubing wellhead temperature, and tidal magnitude. The observed pressure fluctuations exceeded the pressure change from tidal effects, suggesting that temperature changes within the annulus, likely due to flow through the open ‘C’ annulus, were influencing pressure. This was confirmed by an ROV (Remotely Operated Vehicle) survey revealing bidirectional flow through the ‘C’ annulus. The study led to the decision to seal the ports with custom metal plugs and apply chemical treatments to address Microbially Induced Corrosion (MIC). Post-installation monitoring confirmed the effectiveness of this intervention. This investigation underscores the value of proactive measures and interdisciplinary collaboration in managing offshore gas field operations.

1. INTRODUCTION

The Ichthys gas field, one of the largest discoveries in Australian waters, is in the Timor Sea, approximately 220 km offshore from Broome, Western Australia (Fig. 1). The field connects to the onshore LNG facilities at Bladin Point, near Darwin, through an 889 km subsea pipeline. This vast infrastructure supports the development of two key reservoirs: the Brewster member of the early Cretaceous upper Vulcan formation and the Jurassic Plover formation (Fig. 2). The Plover formation, which consists of fluvial to shallow-marine sandstones, shales, and igneous rocks, presents unique technical challenges, particularly in terms of well integrity due to the higher reservoir temperatures.

The Jurassic Plover formation is characterised by elevated temperatures reaching up to 165°C, necessitating significant adjustments to well architecture and hardware design. These design modifications, undertaken in line with INPEX's Well Integrity and Design Manuals, were aimed at ensuring the well's long-term operability and safety under such extreme conditions. The introduction of 26" and 36" casings and dual cement return ports within the low-pressure wellhead system was a critical part of this effort.
Innovative Geomechanical Approaches to Hydraulic Fracturing and Carbon Capture: A Comprehensive Case Study in Tight Gas Reservoirs of Oman
Authors: Alyaaribi Aflah , Khalid Hinai Hinai , Al-Ghaithi Ali
Published: January 2025

This study explores advancements in hydraulic fracturing and carbon capture utilization (CCU) in the tight gas formations of Oman. By integrating geological, geomechanical, and operational data, this research improves hydraulic fracturing effectiveness and evaluates the feasibility of CCU in depleted reservoirs. Key results include optimized fracture designs tailored for gas extraction and improved models predicting CO2 containment integrity in post-depletion environments. Findings advance Oman's goals of maximizing hydrocarbon recovery while preparing reservoirs for sustainable CO2 storage.

1. INTRODUCTION

The extraction of hydrocarbons from tight sandstone formations, especially in Oman, requires cutting-edge hydraulic fracturing techniques and a detailed understanding of geomechanical properties (Economides & Nolte, 2000). The complexity of these reservoirs, influenced by regional tectonics, formation heterogeneity, and reservoir depletion, has prompted the need for advanced modeling to maximize extraction efficiency and prepare for carbon storage (Fjaer et al., 2008). Additionally, with Oman targeting net-zero carbon emissions by 2050, optimizing depleted reservoirs for CCU presents both challenges and opportunities (PDO Report, 2021).

This study aims to (1) enhance hydraulic fracturing efficiency in tight gas reservoirs, and (2) assess the geomechanical feasibility of CCU in depleted sections. By coupling geomechanical and geological models, our approach enables effective fracturing, while ensuring long-term containment integrity for CO2 storage.

2. GEOMECHANICAL ANALYSES

Several predictive approaches have been formulated to assess depth-dependent variations in minimum horizontal stress (Shmin) within thin, stratified reservoirs, particularly in complex, laminated formations like the Amin reservoirs. These methods primarily utilize well log data coupled with in-situ stress measurements, with diagnostic fracture injection tests (DFITs) commonly serving as a calibration tool. DFITs, a subset of hydraulic fracture (HF) diagnostics frequently used in tight formations, estimate Shmin by analyzing pressure decline post-shut-in, providing crucial insights into local stress regimes. However, the vertical heterogeneity of unconventional reservoirs often restricts the availability of DFIT data across the full stratigraphic column, presenting challenges in capturing complete subsurface stress variations.

Published: January 2025

Solids production can occur in carbonate rocks even with high strength matrix, because of presence of natural fractures and vuggy or weak zones. Solid production is known to be a common factor in many oil and gas producing wells in carbonate reservoirs both at the early production period but also in later life of a reservoir under depleted conditions. There are many geomechanical material properties affecting the magnitude and behaviour of solids production. As part of the work done for a previous paper, a finite element model for an open-hole configuration was built to simulate a real case of solids production on a carbonate reservoir located in Abu Dhabi Offshore Field. This model was further enhanced to be extensively utilised for the scope of the current paper. Several simulations are conducted varying numerous geomechanical material properties of the model to assess the influence of each one of them on the magnitude and behaviour of the solids production. This assessment provides a comprehensive correlation between the variation of each geomechanical material property and the effect it has upon the amount and pattern of solids production. The assessment above and any possible future assessments of this type could guide the choice of completion and help the solid management decisions for the development of such carbonate reservoirs.

1. INTRODUCTION

Solids production is a common industry dilemma in balancing efficient production volumes with damaging solids entering the well and top-side facilities. However, it should also be considered that solids production can occur in carbonate rocks, even with high strength matrix, due to the presence of natural fractures and vuggy or weak zones. A previous paper, (Pourpak et al., 2024) conducted a detailed postmortem analysis of solids produced from a fractured/vuggy carbonate reservoir from an Abu Dhabi offshore field. This analysis provided valuable insights regarding the mechanisms of solids production, and was supplemented with calibrated advanced finite element simulations. This paper further develops the modelling to explore the geomechanical parameters space of downhole and drilling conditions which may affect the volumes of solids produced. This aims to provide general guidance for operations in circumstances where data acquisition may be limited.

Published: January 2025

Jimsar shale oil represents a significant unconventional oil and gas resource within China's ultra-deep tight reservoirs. Multistage hydraulic fracturing with multi-cluster perforation in horizontal wells is one of the key technologies for developing Jimsar shale oil. However, due to the characteristics of Jimsar's reservoir, such as ultra-deep, low permeability, strong heterogeneity, and dispersed sweet spots, there are challenges including non-activation of some fracturing clusters and low production contribution. Therefore, it is crucial to comprehensively consider both geological and engineering sweet spots when optimizing the positioning of fracturing stages and clusters. In this paper, reservoir petrophysical properties were classified to characterize the geological sweet spots in horizontal wells, and a K-means clustering algorithm was applied to establish an intelligent optimization model for selecting fracturing stages. Additionally, the downhole mechanical specific energy was used to characterize the rock's mechanical strength, which served as the basis for selecting the optimal engineering sweet spot for fracturing cluster positioning. Finally, practical factors such as field operations, casing collar locations, and bridge plug positions were integrated to achieve balanced fracture initiation. The research results provide a new method for intelligent design of fracturing stage and cluster positioning in hydraulic fracturing, aiming to achieve uniform initiation of multi-cluster fractures and enhance production.

1. INTRODUCTION

The Jimsar Sag is an important demonstration area for shale oil development in China (Hu et al. 2022), with horizontal wells combined with multistage hydraulic fracturing being the key technology for developing this reservoir. The Lucaogou Formation oil reservoir in the Jimsar Sag, a primary lacustrine mixed-type shale oil reservoir currently under exploration and development, represents a major oil and gas exploration area in the Junggar Basin (Chen et al. 2024). This reservoir is characterized by deep burial, low porosity, low permeability, strong heterogeneity, and dispersed sweet spots, leading to uneven stimulation effects during multistage hydraulic fracturing (Wu et al. 2024).
Rapid Field-Scale CO2 Storage Simulation Tool with Geomechanically Constrained Fault Leakage

Published: January 2025

Geological carbon dioxide (CO2) storage is vital for climate change mitigation, but CO2 leakage, particularly through faults, poses significant risks. Accurately simulating the impact of fault properties across scales is crucial for predicting field-scale CO2 injection and storage outcomes. However, this task is challenging due to limited knowledge, data scarcity, and computational constraints. This study introduces a fast tool for CO2 leakage risk assessment that addresses these challenges. The tool combines a vertically integrated reservoir model with an upscaled fault leakage function based on source/sink relations. It conceptualizes faults as zones of increased vertical permeability in the caprock and reduced horizontal permeability in the reservoir. A steady-state flow approximation estimates CO2 leakage along faults. Geomechanical effects on fluid flow are modeled by coupling fault porosity and permeability, amongst several other parameters with effective stress using constitutive relations. A decoupled method based on Geertsma's uniaxial expansion coefficient, assuming zero lateral strain and constant total vertical stress is used here. Example simulations are shown to illustrate the impact of geomechanically constrained fault parameters such as capillary entry pressure and permeability on fault leakage. The fast model presented in this study is a valuable tool for identifying uncertainties in key fault parameters and other constitutive relations that affect the behavior of the storage reservoir and potential fault leakage outcomes.

1. INTRODUCTION

Geological carbon dioxide (CO2) storage, particularly in saline aquifers, is essential for mitigating climate change (Krevor et al., 2023). These aquifers have substantial storage capacities, but successful implementation relies on secure containment of CO2. Leakage poses risks to mitigation efforts and undermines public trust in Carbon Capture and Storage (CCS). Faults are critical in this context, as they can either act as structural traps that confine CO2 or serve as leakage pathways (Knipe et al., 1998; Snippe et al., 2021). As CCS deployment increases, encountering faulted storage formations is inevitable. Faults are complex geological structures with a low-permeability core surrounded by a fractured damage zone, which can increase leakage potential (Fig. 1) (Rizzo et al., 2024). Fault leakage is influenced by various factors, including geometry, architecture, stress regime, and rock properties. Injection-induced changes can reactivate faults, potentially creating new leakage pathways. Sub-seismic fractures within damage zones introduce significant uncertainties in CCS operations due to limited understanding of their presence and properties.
Technologies to Mitigate Geomechanical Challenges of Deepwater Resource Development
Authors: Gupta M. , Ramli A. , Sedaralit F.
Published: January 2025

Deep-water fields offer substantial opportunities due to their high reservoir quality, leading to significantly higher production rates and reserves per well compared to shallow-water fields. However, deep-water environments present unique engineering and geoscience challenges, particularly related to geomechanics. One of the key sub-surface characteristics of deep-water fields is mechanically weak formations, a result of the reduced lithological column being replaced by seawater. This translates to lower vertical stress, while pore pressure remains similar to shallow-water fields. These conditions pose several geomechanical challenges that impact drilling, completion, reservoir production, and overall reservoir management. Common issues in deep-water fields include drilling losses, sand production, and limited injectivity for pressure maintenance.

This paper assesses various technologies used to mitigate these risks and highlights that approaches successful in shallow-water fields may not directly translate to deep-water environments. Specifically, the methodologies discussed address four key areas of deep-water geomechanics: wellbore stability in low fracture gradient formations, sand production and prevention in unconsolidated formations, water injectivity in low minimum horizontal stress environments, and reservoir geomechanics for simulation modeling and production forecasting. For wellbore stability, stress mapping and careful well trajectory selection are essential to avoid collapse or fracturing during drilling. Sand production prevention in weak, unconsolidated formations requires optimized proppant selection and advanced completion techniques. Water injectivity is constrained by the risk of fault activation, necessitating precise control of injection rates to prevent fault slippage. Finally, incorporating geomechanics into reservoir simulation models improves production forecasting by accounting for stress-induced changes in reservoir properties such as porosity and permeability. This paper presents workflows, methodologies, and engineering solutions derived from actual field applications, offering a practical assessment of how to overcome the geomechanical challenges of deep-water developments.

1. INTRODUCTION

Deepwater environments present a unique set of geomechanical challenges due to the significant replacement of overburden rock with seawater, as depicted in Figure 1. This reduction in overburden results in lower vertical stress on the reservoirs in deepwater fields, as shown in Figure 2. Compared to shallow water fields, this shift in stress has far-reaching impacts on the subsurface characteristics and influences all stages of deepwater drilling and development. In particular, three key geomechanical challenges must be addressed: (i) drilling through formations with low fracture gradients, (ii) producing hydrocarbons from unconsolidated formations, and (iii) injecting water into formations with low minimum horizontal stress.
Ensuring Protection of Critical Turtle Nesting Habitat: 3D Geomechanical Modelling Estimates Production-Induced Subsidence at Torosa Field, Browse Basin, Australia

Published: January 2025

Coupled geomechanical approaches are imperative for optimizing field development planning. This paper concerns a subsidence study for Torosa field, Western Australia with a focus on the turtle nesting habitat at Sandy Islet—a sand accumulation located on the reef above the gas reservoirs. This involved building a 3D geomechanical model incorporating structural complexity and rock heterogeneity, followed by adopting a one-way coupling scheme to assess outcomes of three proposed development plans. For the scenario named "REF Case", the maximum predicted subsidence at the end of depletion is less than 51.8 mm at the centre of the field and less than 3 mm at Sandy Islet. The sensitivity analyses performed to account for uncertainty involved scaling down the Young's modulus and Poisson's ratio by 10% throughout the overburden. The results indicate that subsidence is insensitive to the variations of the overburden deformation properties but affected by the intensity and distribution of depletion.

1. INTRODUCTION

The petroleum industry had little appreciation in the early days of the field scale extension of geomechanical influences in the reservoir. The most evident manifestation of the consequences of production-induced stress changes is "subsidence"—a sinking of a surface, such as the ground level in an onshore area or the mudline in a submarine setting—relative to a stable reference point. Subsidence was first noticed in 1918 at the Goose Creek field, Texas, USA. Since then, petroleum geomechanics has come to play an increasingly important role in predicting and quantifying the effects of operations, with the obvious focus on mitigating the economic ramifications of subsidence.

This paper concerns the offshore Torosa gas field, Western Australia, with the key Jurassic reservoirs lying approximately 4000 m TVDSS beneath Scott Reef. The field had undergone an extensive appraisal drilling and seismic acquisition campaign between 2005 and 2012, and the Browse Joint Venture is seeking to develop Torosa field. The integrated geomechanical study presented herein is important to predict the impact of subsidence on a turtle nesting habitat at Sandy Islet—a sand accumulation located on the reef above the gas reservoirs.

Daily Life at the Border
Authors: Ortega-Muñoz Allan
Published: January 2025

Information about the nineteenth-century social history of the southern border of the peninsula of Yucatan—bordering with British Honduras—is scarce to historians, anthropologists, and the public. This chapter is an osteobiography of two persons, one man and one woman who, based on osteological characteristics (gracile bones, epigenetic traits, and more, in the case of the man) and location of burial (woman was buried in the presbytery) were considered aristocrats. They lived and died by the mid-nineteenth century in a town named Villa of Salamanca de Bacalar in Quintana Roo, Mexico. The osteobiographic approach rests on the theoretical framework of the bioarchaeology of personhood. It also rests on the present aspects of life histories reconstructed using the combined physical evidence from taphonomy, mortuary context, and skeletal analyses. Finally, the approach uses the material culture found in association with the inhumed bodies. The approach taken here follows an “imagined narrative” and represents a departure from the notion of fictional narratives. The fictional images with historical accounts and osteological and mortuary analysis recreate multiple perspectives of lived experiences. This narrative emphasizes the intersecting roles of agendas, genders, ages, social status, ethnicities, and labor activities, of both personages buried in Bacalar, as documented in the historical record of the period.
Osteobiography
Authors: Robb John
Published: January 2025

This chapter explores the theoretical underpinnings of osteobiography. Osteobiography seems like a straightforward idea—telling the story of an individual human life through skeletal remains—but biography presumes an ontological framework about what is human, what is alive, and what is an individual. In practice, we end up writing different osteobiographies for different purposes: to familiarise the past, to analyse it, or to understand its alterity. This chapter explores the implications of these variances by discussing issues such as whether we should give names to the people we are biographizing.

Estratégias logísticas para movimentação de produtos têm impacto significativo na eficácia das redes de transporte e fornecimento. A definição de rotas para veículos de carga é um dos problemas com grande impacto nos processos logísticos. Soluções tradicionais de roteirização, tais como caixeiro viajante ou redes de filas, geralmente combinam parâmetros de distância e tempo para escolha de rotas. No entanto, há fatores relevantes que podem melhorar a efetividade na roteirização. Por exemplo, janelas temporais de atendimento nas paradas, rastreabilidade e sombreamento, tipo de carga, velocidade, qualidade da pavimentação dos segmentos de rota, entre outros. Soluções tradicionais não facultam a definição de um conjunto mais amplo, configurável e interdependente de fatores importantes na geração de rotas. Este trabalho apresenta uma solução por Modelagem e Simulação para combinar múltiplos fatores no processo de roteirização. Como resultado, o modelo sugere a rota que melhor atende, de forma combinada, o conjunto de propriedades desejável para cada rota.
