Z Wang, Z Ning, W Guo, W Lu, F Lyu, G Liu - SPE Res Eval & Eng, 2023 - onepetro.org
Waterflooding will induce the opening and extension of fractures, which will create some
water flow channels. Due to fracture multiclosures, the obtained fracture half-length from …

Production-induced stress change in and above a reservoir pierced by two salt domes: a geomechanical model and its applications

PMTM Schutjens, JRR Snippe, H Mahani, J Turner… - SPE Journal, 2012 - onepetro.org
Production decreases the pore-fluid pressure and increases the effective stress acting on
the load-bearing-grain framework that makes up the reservoir. As a result, the reservoir …
