Retarded Fluoboric Acid Multipurpose System Enhanced Oil Production and Increased Water Injection in Reservoirs with Moderate to High Permeability

Abstract This paper presents the successful application of retarded fluoroboric acid multipurpose system (R-HFB4 system) and how it improved oil production in the A and B sandstone reservoirs (lower and upper layers) in fields located in the east basin of Colombia. Optimizing investments and operating time in workover operations have been identified as one of the most important challenges around the world during the last years. Specifically, the reservoir A (lower and upper sands) has
