This paper provides a comprehensive review on the application of proppants to maintain
fracture permeability over the lifetime of a well based on published observations from …

Tight hydrocarbon reservoirs require stimulation to improve the recovery of oil and gas
resources. Hydraulic fracturing is a technique extensively employed in the oil and gas …

Hydraulic fracturing technology is widely utilized to enhance gas drainage efficiency in
underground coal mines. Water plays a crucial role in gas migration within coal after water is …

In this study, we have investigated the effect of various organic acids (hexanoic, lauric,
stearic, and lignoceric acid) and nanoparticles (silica and alumina) on various geo-storage …

A computational model for water migration in porous media is developed based on the CT
images of coal samples to study the effect of dominant pores and fractures on water …

Acoustic emission (AE) experiments of Yuwu and Guangli coal samples under uniaxial
compression were carried out by using the electro-hydraulic servo pressure testing machine …

Evaluation of stress sensitivity of multiscale pores in coal seams stimulated by hydraulic
fracturing or that disturbed by underground mining is significant to coalbed methane …

Hydraulic fractures can enhance well productivity from stress-sensitive naturally fractured
reservoirs, such as coalbed methane or coal seam gas (CSG) reservoirs. Graded proppant …

Turbulent flow in fluid-driven fractures exerts important effects on the hydraulic fracture
extension, fracture geometry, and proppant transport. Based on linear elastic fracture …

Permeability is an important indicator of coalbed methane production. Previous classical
theoretical permeability models under unconstrained boundary conditions have difficulty …
