Optimization of refracturing timing in tight oil reservoirs based on an oil water two phase flow model

Abstract Repeated hydraulic fracturing is essential for sustaining production in tight oil reservoirs due to rapid post-stimulation decline rates, yet optimizing its timing remains challenging. This study develops a two-phase (oil-water) flow model using finite difference methods to simulate fractur...
