In order to study the fracture propagation behavior after interaction between hydraulic fractures and natural fractures, cohensive unit of Abaqus finite element software is used simulate influence in rock on fractures. The simulation results show that when approach angle kept constant, as in-situ stress difference increases, are more likely penetrate expand along direction maximum horizontal pr...

Natural fractures act as critical flow channels and reservoir space in the Lucaogou Formation tight of Jimsar Sag. It is essential to identify main controlling factors natural order achieve efficient development oil this area. There are mainly three types fractures, including tectonic diagenetic abnormal overpressure-induced fractures. Diagenetic predominantly bedding seams. The fracture affect...

Mitchell and his team of geologists and engineers began working on the shale challenge in 1981, trying different combinations of processes and technologies before ultimately succeeding in 1997 with the use of a “slick-water” frac that made Barnett Shale economical to develop and in turn changed the future of the US natural gas industry [7]. Continuing on Mitchell’s success progress followed a p...

Shear fracture network is important to the hydraulic fracturing treatment of a shale gas reservoir. In this paper, the formation of shear fracture network is investigated by a Displacement Discontinuity Method (DDM) based model. The results show that the sliding of fracture surface is irreversible but may change significantly after fluid pressure dissipates. The final sliding distance is differ...

fractures are considered as one of the important structures in fractured reservoirs due to their effect on fluid currents and reservoirparameters such as porosity and permeability. fracture parameters can only be directly calculated with core and image logs. cores haveserious limitations, so image logs are the best method. the aim of this study is the systematic fractures analysis of the asmari...
