IMPROVING THE EFFICIENCY OF WELL KILLING IN RIPHEAN CARBONATE RESERVOIRS

Petroleum Engineering
This article presents the laboratory test results of a study of well-killing fluids designed to improve the efficiency of wells operating in the fractured carbonate reservoir (Riphean) of the Kuyumbinskoye oil and gas condensate field, which is classified as complex due to its heterogeneous geological structure, abnormally low reservoir pressure, and ...
