Abstract null null To address the wellbore instability risk during drilling in hydrate reservoirs, a fully coupled wellbore–reservoir model for horizontal drilling through a hydrate reservoir is presented, which considers the dynamic heat and mass transfer between the wellbore and reservoir and the coupling interactions between the fluid flow, heat transfer, and evolution of mechanical properties in hydrate-bearing sediments. A numerical method based on COMSOL Multiphysics + MATLAB was first pro...

Abstract null null The purpose of this study is to visually reconstruct the minerals touched by connected pores and fractures and reveal their demineralization process, which is of great significance for the analysis of permeability evolution during CO2-ECBM process. Two samples collected from Qinshui basin were taken as the research object. Firstly, the definition, reconstruction, and demineralization processes of such minerals were realized, and the evolution of pore network model under differ...

Abstract null null Consolidation deformation is prevalent in hydrate-bearing sediments due to oceanic currents, the erection of jack-up drilling rig platforms, depressurization exploitation, etc. However, the microstructural behavior of hydrate-bearing sediment during consolidation remains unclear because of experimental challenges. Herein, using a novel microfocus X-ray CT-based triaxial testing apparatus, we present a series of results to reveal the microstructural evolution of hydrate-bearing...

Abstract null null 3D fracture network modeling remains a challenging work with the wide application of microseismic monitoring in multi-stage hydraulic fracturing. Due to the existence of invalid noise events, conventional methods often have significant deviations in detecting fracture geometry for fracture modeling after multi-stage fracturing. null To solve the problem, we present an integrated 3D fracture reconstruction method that incorporated random sampling consensus algorithm (RANSAC), d...

Abstract null null Gas transport processes in low-permeable (tight) sandstones at elevated pore pressures involve a combination of fluid-dynamic (slip flow) and poro-elastic or rock-mechanical stress (pore and bulk compressibility) effects. To assess the interdependency of both processes, permeability experiments with gas (argon) were combined with volumetric strain measurements. The flow studies were performed under controlled effective stress (10, 20 and 30 MPa) with pore and confining pressur...

Abstract null null Brittleness is a significant indicator of a series of engineering problems in the oil and gas community. However, the majority of brittleness evaluation methods focus on brittle rock, but few pay much attention to weak-brittle rock. In this study, an attempt has been made to study the relationship between released acoustic emission (AE) energy and brittleness during the fracture process of rock samples. An accumulative acoustic energy-based brittleness evaluation method was pr...

Abstract null null Hydraulic fracturing is regarded as an effective tool to stimulate the reservoir and ensure economic production of gas. The process of exploitation of these resources is largely influenced by small spheres called proppants. The main goal of hydraulic fracturing is to generate a wide fracture network in the medium. Injecting proppants at higher concentrations into these fractures tends to maintain conductivity by keeping them open, so that smooth flow of fluids into the wellbor...

Abstract null null Liquid leakage and gas slippage through the annulus between an upward moving plunger and vertical tubing significantly reduce the uploading efficiency of the accumulated liquid during plunger lifting in gas wells. Understanding the characteristics of gas-liquid two-phase flow in the annulus during plunger lifting process is crucial to enhance the fluid seal and to improve the plunger lift technology, but investigations of this important issue in literature is extremely limited...

Abstract null null Casing deformation and micro-seismic event in shale gas reservoir has been of growing interest in the industry, which is attributed to the fault slip induced by multi-fracturing in shale gas wells. It has been widely acknowledged that the variation of pore pressure affects fundamentally the fault slip. However, the currently reported analytical models of pore pressure is not available to specially couple the key effects of shale anisotropy and accumulation of fracturing fluid ...

Abstract null null In this study, a dynamic corrosion device for cement paste was developed according to the underground conditions of oil and natural gas wells, which possess a largely dynamic and constantly migrating corrosive medium. Using CO2 as the corrosion medium, the effects of the three corrosion conditions, namely static non-migration, dynamic non-migration, and dynamic migration of the corrosion solution, on the corrosion process of cement paste were studied. The results revealed that...
