Pilot production of liquid drilling waste injection into aquifers was successfully carried out in South Priobsk field, which "Gazpromneft-Khantos" develops.
Four disposal wells were selected as site for testing with a maximum total flow injection to 89.8 cubic meters per day and injection wellhead pressure of 160 atmospheres. Sealed packers were pre-installed into the wells to comply with all environmental safety standards and corrosion inhibitor was applied to provide a waterproof layer.
