Prediction efficiency of immiscible Water Alternating Gas Performance by LSSVM-PSO algorithms
Kengessova, Aizhan (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020)In this work the aim is developing LSSVM-PSO model capable of capturing the interplay between the most influential parameters (mechanisms) and recovery factor (RF) of WAG process in layered reservoirs. In a previous work ... -
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 ... -
Simulation of Water Management Processes
Nygård, Jan Inge (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Conformance control practices are commonly used to tackle issues related with injected fluids bypassing potentially oil-bearing formations, due to the presence of conductive fractures. To improve the prospect of such a ...
