Summary The article describes the development of a technology meant to kill wells in fractured carbonate reservoirs of the Republic of Bashkortostan with abnormally low reservoir pressure (ALRP) and high gas-oil ratio. Initially, various technologies were tested in wells to solve this problem: invert emulsion muds, biopolymer solutions, crosslinked gels and water-swellable polymers. However, they demonstrated low efficiency. A new killing technology based on a foam-gel system was selected and adapted to the existing conditions to enhance killing efficiency in complicated geological conditions. Successful tests were performed in three wells of reef fields with ALRP.
