Oil recovery enhancement using gas and water alternative injection to oil reservoirs

چکیده مقاله

Various methods have been used to increase reservoir recovery coefficients and production improvement among them alternative gas and water injection is appropriate method.

It is secondary process of oil recovery enhancement that is began from 1950 and has been used extensively in this method, to alternative injection, mixed homogeneous gas and water has been performed in permeable bed due to relative permeability, low dynamic proportion of gas and water would be decreased compared to oil and macro and micro productivity would be improved and increased.
