Prediction of Oil Recovery Factor in Stratified Reservoirs after Immiscible Water-Alternating-Gas Injection based on PSO-, GSA-, GWO-, and GA-LSSVM
Andersen, Pål Østebø; Nygård, Jan Inge; Kengessova, Aizhan (Peer reviewed; Journal article, 2022-01)In this study, we solve the challenge of predicting oil recovery factor (RF) in layered heterogeneous reservoirs after 1.5 pore volumes of water-, gas- or water-alternating-gas (WAG) injection. A dataset of ~2500 reservoir ... -

Simulation of immiscible WAG injection in a stratified reservoir -- performance characterization using a new dimensionless number
Nygård, Jan Inge; Andersen, Pål Østebø (Peer reviewed; Journal article, 2019)Water alternating gas (WAG) is a well‐established enhanced‐oil‐recovery process where gas and water are injected in alternating fashion. Good volumetric sweep is achieved as water and gas target both the oil residing in ...
