An Evaluation of Water and Gas Injections with Hydraulic Fracturing and Horizontal Wells in Oil-Saturated Shale Formations

A variety of methods are examined in this study order to improve oil recovery from low-permeability heterogeneous reservoirs oil-saturated shale deposits. Calculations based on the fluid flow model revealed that water and gas injection was effective, horizontal directional wells, including those employing hydraulic fracturing evaluated study. Moreover, wells with vertical completions found be one most effective for However, when fracture length is hard achieve, has been a more efficient way enhance than injection. Furthermore, drilling technology central part reservoir.
