... coalbed methane (CBM). However, deep coals generally have complex pore structure and exhibit strong anisotropy during the gas transport process. The increase of formation depth also generates high-temperature, high-in-situ-stress, and high-reservoir-pressure conditions. There is a matrix-fracture/cleat...

... Abstract An advanced numerical simulation method was developed to accurately characterize the heterogeneous geomechanical damage of heterogeneous matrix, hydraulic fractures, and natural fractures during production. The proposed model can automatically obtain the geomechanical damage correction...

For different reservoir types and different fracture dimensions, different models are adopted to depict the spatial distribution and fluid flow characteristics of fracture-matrix, matrix-matrix and fracture-fracture...

..., based on its exploration data it provides us with a production potential or estimate of 1000 bbl/d of oil. Thus, we can register the likelihood of this carbon emission activity as "Certain (5)", on the proposed sustainable risk matrix. Risk rating of the carbon emission activity Risk Description...

Furthermore, if the core material was of initial, non-produced state without the influence of production fluid flow on the reservoir matrix, it would allow for significant information...

Injection is carried out at a number of rates below fracturing pressure. At each rate injection...

... of organic matter, which results in nanoconfined effects. In this work, on the basis of the boundary slip phenomenon and the fractal scaling theory, a model for oil transport in shale matrix is established considering nanoconfined effects and adsorbed organic matter. The results show that it is necessary...

..., commonly referred to as fracking, is a widely used technology to enhance the productivity of low-perm reservoirs and the aqueous-based fracturing fluids use guar as the rheology builder. Residual polymer layer over the fractured surface results in a reduced matrix to fracture permeability, causing reduced...

... Abstract In common practice, gravel pack completion is beneficial as sand control in a typical unconsolidated sandstone reservoir. However, with poorly sorted sand grains, fines migrate and deposit at the gravel-pack matrix, causing permeability reduction and hence, decreasing well productivity...
