With the continuous advancement of oil and gas field development technologies, there has
been an increasing focus on the exploration of unconventional oil and gas resources, such …

Decoupling the molecular structure from the pore structure is challenging under
experimental conditions; this hinders the independent investigation of the effect of the …

The migration and distribution of oil in oil-bearing coal significantly influence the gas
drainage and gas-outburst control during mining activity. To quantitative describe the oil/gas …

Transverse anisotropy plays an important role in the engineering behavior of rock masses.
This study examines the transverse anisotropic spatial variations and evaluates them using …

Tight-sandstone oil and gas resources are the key areas of unconventional oil and gas
resources exploration and development. Because tight-sandstone reservoirs usually have …

During the true triaxial hydraulic fracturing experiments, the compression stress applied to
the specimen surface cannot be transferred to the interior immediately, resulting in …

Conventional hydraulic fracturing techniques are often found problematic for extracting
geothermal energy in hot dry rock (HDR). As an alternative, employing the less viscous gas …

To achieve long-term and efficient gas extraction in soft, low-permeability coal seams, this
study conducted hydraulic fracturing experiments on coal-rock complexes under true triaxial …

Under the effect of the goal of carbon peaking and carbon neutrality, the use of supercritical
CO 2 has gradually become a research hotspot as a new waterless fracturing fluid …

Efficient technology is needed to realise reservoir stimulation for deep geothermal energy
exploitation. However, the main control parameters of traditional hydraulic fracturing …
