Optimization of Shut-In Time for Hydraulic Fracturing-Assisted Oil Displacement in Offshore Low-Permeability Reservoirs

ACS Omega, Journal Year: 2025, Volume and Issue: 10(12), P. 12530 - 12542

Published: March 20, 2025

To optimize the shut-in time for hydraulic fracturing assisted oil displacement in offshore low-permeability reservoirs, a coupled mathematical model encompassing injection, well, and production is established. The accuracy of validated using data. law pressure diffusion oil–water two-phase flow during well process clarified, mechanism to enhance recovery summarized. sensitivity analysis conducted, then main controlling factors affecting optimal are identified. research results indicate that primary function effect formation energy supplementation after thereby further increasing swept volume, greater geological reserves, ultimately enhancing recovery. During initial stage larger portion reserves controlled mainly by fluid diffusion, while later stage, exchange achieved imbibition effect. cumulative injection coefficient before displacement, permeability, which should be given special attention on site. provide theoretical basis design operations reservoirs.
