Calculation of Water Injection Response Time in a Low-Permeability Anisotropic Reservoir

Resumo

We propose a model for predicting the response time of a production well responding to a change in pressure in the injection well while developing a low-permeability oil reservoir. The governing equation is derived based on a nonlinear seepage law and the method of successive substitution of steady states, and takes into account the anisotropy of the oil formation. We show that this model permits more accurate calculation than the conventional model.
