Reservoir numerical simulation study for refracture reorientation

In this paper,black-oil model is used to study how fracture penetration coefficient and fracture conductivity affect the oil recovery performance of production wells in different reservoir permeability when refracture reorientation.The study shows that the edge wells of unfavorable fracture azimuth are the most suitable wells to treat with reorientation refracture and the length of these wells should be longer than common refracture.The fracture length of the edge wells of favorable fracture azimuth and corner wells should be designed with common refractures.Moreover,reorientation refracture need higher fracture conductivity than common refractures.
