... simulation methods are used to establish a true three-dimensional hydraulic fracturing model for reservoirs with natural fractures, and the quantitative evaluation indicators of stress shadow area and activation degree of natural fractures are formed. By studying the effects of different natural fracture...

...Physical model Shale matrix consists of organic pores and inorganic pores, and it develops micro-fractures. After hydraulic fracturing, the reservoir forms multi-scale fractures, including laminated fractures and hydraulic fractures. Different-scale media, such as organic matter, inorganic...

... Abstract Low permeability, naturally fractured reservoirs such as coal seam gas (CSG, coalbed methane or CBM) and shale gas reservoirs generally require well stimulation to achieve economic production rates. Coupling hydraulic fracturing and micro-proppant or graded particle injections (GPI...
