... Abstract Accurate calculation of adsorbed shale gas content is critical for gas reserve evaluation and development. However, gas adsorption and desorption experiments are expensive and time-consuming, while physics-based models and empirical correlations are unable to accurately capture...

... CO 2 injection to increase oil recovery from shale reservoirs, it also points to some major issue that should be considered when applying this EOR method in unconventional shale in order to optimize the overall procedure. Experimental Procedure shale oil Upstream Oil & Gas shale gas...

... Abstract Multistage hydraulic fractured horizontal wells (MHFHWs) are widely used in most shale gas reservoirs around the world. Hydraulic fracturing treatment can create hydraulic fractures and activate existing natural fractures to generate a complex fracture network to significantly improve...
