... Abstract Recently, supercritical CO 2 (sc CO 2 ) injection in shale gas reservoir has drawn great attention for its potential to sequestrate the greenhouse gas underground and enhance shale gas recovery. To further understand the mechanisms of sc CO 2 sequestration and competitive adsorption...

... Abstract In this work, we derive an effective mean free path (MFP) model for the confined gases in nanopores of shale gas reservoirs by taking into account the effects of the geometrical termination and the surface-gas interaction of the boundary. Among which, the effect of the surface-gas...

... Abstract Pore size distribution is of extreme important in the shale gas reservoir evaluation and exploration. However, shale is kind of quit complicated material, and traditional well logs (i.e. acoustic, density and neutron) only measure total porosity, while it cannot quantity the different...

... Summary Single-hydraulic fracture numerical simulation models of a hypothetical tight/shale gas reservoir have been built for comparing different field development designs from either the perspective of maximizing recovery with a specific number of hydraulic fractures per section or minimizing...

The experimental results indicate that huff-n-puff gas injection could be an effective approach to enhance gas-condensate recovery in shale gas reservoirs. condensate reservoir Upstream Oil & Gas enhance condensate recovery thermal method...

... Summary The Lower Silurian Qusaiba Hot Shale (QHS) has long been known as the major source rock in the Paleozoic petroleum system of Saudi Arabia. However, during the last few years, special focus has been directed toward this formation as a candidate for unconventional shale gas reservoir due...

... Summary The advances in horizontal drilling and hydraulic fracturing technologies have enabled shale gas production economically. Although there are a huge number of horizontal wells drilled in many shale gas reservoirs, well performance and completion effectiveness are still poorly understood...

... Summary Horizontal drilling and multi-stage hydraulic fracturing are the two critical enabling technologies to facilitate a rapid development of shale gas reservoirs. The process of hydraulic fracturing often creates complex fracture networks, especially in some shale reservoirs with a high...

... Summary Unconventional plays such as tight gas and shale gas reservoirs have potential of becoming the main source of cleaner energy in the 21th century. Development of unconventional fields requires engineered hydraulic fracturing that facilitates access to larger volumes of the reservoir...
