IOR-17 THERMOREVERSIBLE POLYMER GELS USED TO INCREASE CONFORMANCE OF HIGH- VISCOSITY RESERVOIRS BY HEAT STIMULATION L.K. ALTUNINA and V.A. KUVSHINOV Abstract 1 Physico-chemical rheological and filtration characteristics as well as oil displacing capacity of gel forming thermoreversible polymer solutions with lower critical dissolution point have been studied in the temperature interval ranging from 90 to 250 o C. Such gel forming solutions were prepared based on the system cellulose ethers – carbamide – aqueous phase. Gel forming solutions have been proposed to regulate filtration patterns and to increase conformance of highviscosity oil reservoirs by heat stimulation. The experimental studies were
