Abstract

The paper analyzes the field results of different selective fluid shut-off treatments carried out at the largest Hungarian oil field during the past decade. The polymer/silicate method was routinely and profitably used for water shut-off in oil producing wells. Recently a novel method based on is-site hydrolysis and flocculation of inorganic compounds is tested with the same goal. A complex foam/gel double injection technique was developed and used for restriction of gas conning in oil producing wells. Restriction of water conning and side invasion by injection of alcoholic polymer solutions into gas producing wells is also in the centre of field management. Although diverse experiences were obtained, the positive results and the substantial oil production entourage the experts to continue the laboratory and the field studies and to implement prospectful methods.
