Rock fractures are crucial conduits for fluid flow in fractured rock masses. Three-dimensional
(3D) discrete fracture network (DFN) modeling approach, which can explicitly characterize …

Anhydrous liquid nitrogen cracking low-permeability coal seams can improve the efficiency
of coalbed methane extraction. Under normal pressure, liquid nitrogen (-196℃) contacts the …

Liquid nitrogen (LN2) fracturing is an anhydrous fracturing technology that enhances coal
permeability and supports unconventional oil and gas exploitation. In this Review, we …

Shale reservoirs have been a significant focus of hydrocarbon production over the past few
decades, and the mechanical assessment of target shale reservoirs has been critical to …

Freezing by liquid nitrogen (LN 2) can noticeably alter the rock structure of rocks, which can
find application in the extraction of clean natural gas for shale gas reservoirs. More natural …

In order to study the productivity dynamic evolution laws of shale gas horizontal well, a
multiscale seepage theoretical model considering the fluid–solid coupling effect is proposed …

Liquid nitrogen (LN) fracturing is an efficient technology for the development of
unconventional gas resources. Due to continuous injection of cryogenic LN, the reservoir …

Studying the law of coal adsorption capacity under the action of liquid nitrogen is very
important for the extraction of coalbed methane. For this study, the lignite's ability to adsorb …

Liquid nitrogen (LN2) can dramatically deteriorate the rock and create more fractures in high-
temperature reservoirs, such as deep hydrocarbon reservoirs. The present study …

To reveal the breakdown mechanism of dry hot rock (HDR) induced by liquid nitrogen (LN)
fracturing, the laboratory tests were performed on high temperature granite using …
