Enhanced Oil Recovery

Description

Enhanced oil recovery (EOR) - Enhanced gas recovery (EGR) - 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, steam-drive, and in-situ combustion - Miscible displacement of methane by carbon-dioxide in depleted gas reservoirs - Displacing methane in coal seams by nitrogen - Co-optimization of EOR/EGR/ECBM and carbon-dioxide. references Fundamentals of Enhanced Oil and Gas Recovery from Conventional and Unconventional Reservoirs

Objectives

• Explain the principles and rationale of enhanced oil recovery (EOR), enhanced gas recovery (EGR), and enhanced coal bed methane recovery (ECBM). Screen reservoirs to select suitable enhanced recovery methods. Evaluate sweep and displacement efficiency and estimate trapped oil saturation. Describe miscible and immiscible gas injection, polymer flooding, water-alternating-gas (WAG) injection, and thermal recovery methods. Discuss the use of carbon dioxide and nitrogen in displacing methane and in co-optimizing recovery.
