..., and coal bed methane. Shale gas, as a clean energy source, has good development potential and value [2] , and China has abundant shale gas resources [3] , mainly concentrated in the Sichuan Basin and the Ordos Basin [4] . The Sichuan Basin, as the main area of shale gas resources in China and one...

... in laminated reservoirs using an integrated reservoir-geomechanics-fracture model. Using a dataset from the Sichuan Basin, Western China, a multilayer deep shale gas reservoir model is built with 4 horizontal parent wells spaced at 450 m in the lower producing layer and child wells to be placed in upper...

... Abstract Fluid typing identification is one of the greatest challenges in Sichuan Basin, China. To solve this problem, various borehole measurements are introduced by operators, such as nuclear magnetic resonance and array dielectric logs. These measurements are barely satisfactory...

.... Abstract Shale hydration is an important factor affecting the productivity and flowback rate of shale gas wells. In this paper, we conduct a set of experiments on shale sample from the Longmaxi Formation (LF) located in the Sichuan Basin. The experiment of shale hydration was carried out, and the low field...
