The extraction of coal measure gas has been shifted toward thin gas reservoirs due to the
depletion of medium‐thick gas reservoirs. The coproduction of coalbed gas, shale gas, and …

Accurate prediction of dynamic thermal behaviors during multi-stage hydraulic fracturing is
profound which can avoid performance deterioration of fracturing fluids or failure of …

Secondary hydrate formation or hydrate reformation poses a serious threat to the oil and gas
transportation safety and natural gas hydrate exploitation efficiency. The hydrate reformation …

Low-viscosity slickwater fracturing fluids are a crucial technology for the commercial
development of shallow shale gas. However, in deep shale gas formations with high …

Microfractures play a critical role in the evaluation and exploitation of unconventional
reservoirs. Tight sandstones of the He-1 Member in Shihezi Formation in Hangjinqi area are …

The permeability of CO 2 sequestration is influenced by the characteristics of pore–fracture
structures in coal, yet the flow simulation via the pore network model (PNM) and the controls …

Understanding the fracture effect on the two-phase displacement process in porous media is
potential for fulfilling the efficient development of geo-energy resources. In this paper, a pore …

Thermal maturity of the shales from the Ziliujing Formation of the Jurassic age in the Sichuan
Basin is in the hydrocarbon generation window, which makes it a candidate for shale oil and …

The multi-scale characterization of building materials is necessary to understand complex
mechanical processes, with the goal of developing new more sustainable materials. To that …

Unconventional gas reservoirs comprise natural porous materials, such as shales, with low
permeability, which can limit gas recovery. Pore structure evaluation in shales often relies on …
