Effect of Geological Heterogeneity on the Production Performance of a Multifractured Horizontal Well in Tight Gas Reservoirs

Abstract: Multifractured horizontal wells are widely used in the development of tight gas reservoirs to improve the gas production and the ultimate reservoir recovery. Based on the heterogeneity characteristics of the tight gas reservoir, the homogeneous scheme and four typical heterogeneous schemes were established to simulate the production of a multifractured horizontal well. The seepage characteristics and production performance of different schemes were compared and analyzed in detail by the analysis of streamline … Show more

“…3 Reservoir heterogeneity, such as fractures and faults, has prevented the recovery of crude oil in an economic manner. 4 The viscosity of CO 2 in a normal oil reservoir can be 10−50 times lower than that of the oil, making CO 2 more likely to channel through the oil and preferentially flow through more permeable rock sections. 5 This issue can be solved by adding surfactants to produce in situ CO 2 foams.…”
