The development of hydraulic fracturing and horizontal drilling techniques has promoted the
exploitation of shale gas resources. However, using water has several potential drawbacks …

Acid fracture is a widely applied stimulation technique in carbonate formations; however, it
has yet to be fully engineered. A holistic approach was taken in this study to improve the …

Water-based fracturing fluid has recently garnered increasing attention as an alternative
oilfield working fluid for propagating reservoir fractures and transporting sand. However, the …

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 …

The shale-ScCO 2 reaction and its effect on shale structure are among the key issues that
significantly affect the CO 2 sequestration process and shale gas recovery. To address this …

Adsorbed methane makes up a large portion of the total shale gas-in-place (GIP) resource in
deep shale formations. In order to accurately estimate the shale GIP resource, it is crucial to …

Quantitative characterization of shale gas flow in fractured shale is a key problem in shale
gas extraction. In this study, 3D multi-scale structures in fractured shale were reconstructed …

Abstract Supercritical carbon dioxide (ScCO 2)-based fracturing technology associating with
CO 2 enhanced shale gas recovery is a promising technology to reduce the water …

Carbon dioxide (CO 2) is an alternative working fluid to water for hydraulic fracturing in shale
reservoirs. It offers advantages as a substitute for the use of large quantities of potable water …
