Abstract The highly complex geology of the Sichuan Shale gas play, especially in relation to natural fracture systems at different scales, affects the hydraulic completion efficiency and performance. Ant-tracking-based workflows and borehole image data are regularly used to optimize completion...

.... These permeabilities can be in the range of microdarcies and even as low as nanodarcies with natural fractures (NF) or fissures within the framework which significantly enhance the production levels via secondary porosity mechanisms. In general, the production capability from matrix permeability as identified...

... Abstract The Keshen gas formation is located in the Tarim basin, western China, characterized with developed heterogeneous natural fractures, with most prospective tight gas opportunities. Though high initial gas production rate is commonly achieved, a rapid decline sometimes occurs during...

... is a naturally fractured formation, and it is vital to account for the natural fractures during a simulation study. A discrete fracture network (DFN) model and a 3D mechanical earth model (3D MEM) were created and used to determine the complexity of the hydraulic fracture geometry. The microseismic data obtained...
