To study the deterioration mechanisms of anhydrite rock under the freeze-thaw weathering
process, the physico-mechanical characteristics and microstructure evolutions of anhydrite …

Unconventional resources like shale gas has been the focus of intense research and
development for two decades. Apart from intrinsic geologic factors that control the gas shale …

Hydraulic fracturing has been widely used to enhance reservoir permeability during the
extraction of shale gas. As one of the external input parameters, injection rate has a …

A series of hydraulic fracturing experiments were conducted using Lushan shale cores (50
mm in diameter and 100 mm in length) to unravel the formation mechanism of fracture …

This paper creates single cracked specimens by the prefabricated crack in the middle of a
standard cylindrical specimen of limestone. The MTS815 rock mechanics test system was …

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 …

Shales are intrinsically anisotropic and heterogeneous due to the existence of bedding
planes and natural microfractures. Although the roles of shale bedding anisotropy and …

Understanding and characterization of fracture propagation are crucial for enhancing the
stimulation of low-permeability gas reservoirs. This study investigates the effects of shale …

Oil and gas drilling contractors face many challenges during drilling, mainly related to
wellbore instability. The water-based drilling fluids (WBDFs) are mixed with various swelling …

In this paper, a seepage-stress coupling numerical analysis method is developed to
simulate complex hydraulic fracturing in porous medium, in which the characteristics of …
