Experimental and analytical studies of gas-oil displacement

Authors: A.M. Petrakov, E.M. Simkin, Yu.A. Egorov, T.L. Nenartovich, A.N. Shaimardanov (VNIIneft OAO, RF, Moscow)

Key words: oil recovery, gas injection, low permeability, reservoir simulation model, displacement efficiency, dead oil, recombinate oil sample, relative permeability.

The evaluation of the effectiveness of gas injection technology to increase the recovery ratio of oil from low-permeability reservoirs by results of physical modeling is executed. Hydrodynamic model is built on its basis with the aim to determine the relative permeabilities, which can be used at full-scale simulation of the process of the field development with the use of water-and-gas injection.
