Oil & Gas Recovery

Description

Defining enhanced oil recovery (EOR), enhanced gas recovery (EGR) and enhanced coal bed methane recovery (ECBM). Reasons for EOR/EGR/ECBM-Screening of reservoirs for selection of EOR/EGR/ECBM methods - Sweep and displacement efficiency. Estimating trapped oil saturation- Decreasing residual oil saturation by miscible/near-miscible/immiscible gas injection processes- Controlling mobility at the field scale by polymer flooding and by water-alternating-gas (WAG) injection. Increasing oil mobility by thermal methods of cyclic steam stimulation, steamdrive, and in-situ combustion. Miscible displacement of CH4 by CO2 in depleted gas reservoirs- Displacing CH4 in coal seams by N2 and CO2.Co-optimisation of EOR/EGR/ECBM and CO2.
