IKHN-KA SYSTEMS FOR EOR OF LOW-PERMEABLE RESERVOIRS WITH HIGH RESERVOIR TEMPERATURES

A concept has been developed to use the reservoir energy to generate an effective oil displacing system in situ. Oil displacing IKHN-KA systems have been created to form CO₂ and alkaline buffer system under the reservoir conditions due to high reservoir temperature or heat effect. IKHN-KA systems are compatible with reservoir brines. They increase the efficiency of oil displacement from low-permeable reservoirs in oil fields of West Siberia by 15-22%. The systems are easily producible and ecologically safe. All the components employed are the products of large-scale national industry.

The technology of physico-chemical treatment of reservoirs by IKHN-KA systems allows one to combine the advantages flooding performed by alkaline solutions and surfactants with CO₂ effect. Pilot tests carried out in oil fields of West Siberia have revealed technological and economical efficiencies of IKHN-KA systems.

The technology allows one to produce 20-40 tons of oil in addition per 1 ton of the injected IKHN-KA systems.
