Geophysical Research Progress On Tight Sandstone Reservoir In Sulige Gas Field
Improved Oil and Gas Recovery, 2020 The tight sandstone reservoir in the cooperation block of Sulige gas field is characterized by thin gas-bearing sand, large variation laterally, and strong heterogeneity. Due to the complex surface conditions, and particularly the thick weathered zone, the 3D seismic data presented limited frequency bandwidth.

Deep Underground Science and Engineering, EarlyView.This study investigates the hydro‐mechanical response and fracture evolution in depleted sandstone reservoirs during CO2 injection, considering both direct wellbore injection and hydraulic‐fracture‐assisted injection. The graphical abstract illustrates how CO2 injection induces dynamic stress redistribution, leading to natural fracture activation ...

Energy Science &Engineering, EarlyView.The low‐field nuclear magnetic resonance (NMR) measurements are applied to investigate the seepage characteristics of the single rough joint. The purpose of this paper is to investigate the seepage characteristics of granite specimens with single‐joint channel under the different roughness, confining pressures and seepage pressures.

Energy Science &Engineering, EarlyView.A stress wave propagation model for coal‐rock combinations under in situ stress was established. Taking a coal mine in Huainan, China as the engineering background, isotropic and anisotropic numerical models were constructed. Field engineering practices were carried out to verify the reliability of the conclusions.

Energy Science &Engineering, EarlyView.One‐way FLAC3D‐COMSOL coupled modeling and field validation show that a 150 mm borehole radius with 5 m spacing provides the best coordination of plastic‐zone expansion, stress relief, permeability enhancement, and gas‐pressure attenuation, increasing the pure gas drainage rate by 35.4%. ABSTRACT To rationally determine the borehole radius and borehole

Energy Science &Engineering, EarlyView.This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.
