Problems and Prospects of Gas Methods for Enhancing the Reservoir Hydrocarbon Recovery

D17 PROBLEMS AND PROSPECTS OF GAS METHODS FOR ENHANCING THE RESERVOIR HYDROCARBON RECOVERY Abstract 1 13 th European Symposium on Improved Oil Recovery — Budapest Hungary 25 - 27 April 2005 R.M. TER-SARKISOV VNIIGAZ Razvilka Leninsky District Moscow Region 142717 Russia The paper presents natural and man-caused factors that govern the existence and formation of hard-to-extract hydrocarbon (HC) reserves in the process of their development. A conceptual approach to the problem of enhancing gas condensate recovery by involving hard-to-extract HC reserves into active development at various stages of their recovery from reservoir is described. It was shown that a formed
