Acid fracturing of carbonate rock starts with formation breakdown and fracture propagation
caused by stimulation fluids. The effectiveness of acid fracturing largely depends on the …

In this study, theoretical models have been formulated, validated, and applied to examine
transient pressure behaviour of a fractured vertical well with complex hydraulic and natural …

Fracture closure and proppant settling are two fully coupled processes during both shut‐in
and production. Proppant distribution greatly affects the residual fracture width and …

In this paper, numerical simulations of fractured vertical well in low-permeable oil reservoir
are carried out and two issues: threshold pressure gradient (TPG) in reservoir matrix and …

Coalbed methane production failures through hydraulic fracturing in the Linxing gas field in
China have encountered significant setbacks, hindering efforts to enhance the recovery of …

Nonuniform proppant distribution is fairly common in hydraulic fractures, and different
closure behaviors of the propped and unpropped fractures have been observed in lots of …

Combining horizontal drilling together with hydraulic fracturing greatly improves the
economic viability of exploiting a tight reservoir, while the stress-sensitive effect raises the …

Multistage fracturing horizontal well is the main method of shale oil development. However,
significant differences are observed between fracturing stages productivity due to reservoir …

Proppant distribution has great influence on well performance. It's necessary to investigate
the mechanism of proppant distribution in fracturing treatment. This paper presents a new …

Multiple upscaling schemes for gas transfer in nanoporous media, microporous matrix, core-
scale matrix, and centimeter-scale matrix-fracture systems are investigated. An Open Multi …
