Abstract

At present petroleum engineering has become economic based field hence all efforts are being made to make sure that we squeeze out the last drop of oil from the reservoir Pl. Reservoirs start to deplete with time hence secondary recovery methods are applied. When such methods are also failed, Enhanced Oil Recovery (EOR) techniques remain the only solution for the production of well hence with EOR techniques 30-60 % of oil can be recovered. In EOR techniques we inject gas and/or water to provide energy (driving force) to the reservoir to produce. Currently Simultaneous Water Alternating Gas (SWAG) along with other techniques tends to improve oil recovery by improving reservoir fluids mobility and providing driving force rzJ. Foam can also be added in water alternating gas technique to improve the sweeping mechanism and cut off the gas production and we term such method as Foam Assisted Water-Alternating Gas (FA WAG). In this study, a comparison has been made between FA WAG & SWAG in order to come up with the effective method of EOR, having better oil recovery. Core flooding is to be carried out for the evaluation of both techniques. Hence from previous experiences it has been predicted that SWAG tends to address all recovery related problems economically, where as foam has been seen to address the problems by assisting other Enhanced Oil Recovery Techniques and proved that foam assistance has given better recovery.
