Evaluation of Unique Cross-linked Acid and its Successful Application in Acid Fracturing in the Middle East ///

Andrea Vissotski, Lead Engineer, Treatment Applications Technology, Baker Hughes, a GE company

In carbonate formations requiring highly conductive fractures to enhance production, the creation of long differently etched fractures is necessary. With certain challenges encountered in fracturing carbonate formations, including high leak-off and fast acid reaction rates, the conventional practice of acid fracturing involves complex pumping schemes of pad, acid and viscous diverter fluids to achieve fracture length and conductivity targets. A simplified and cost effective approach to acid fracturing was deployed to a campaign of wells in an oil producing field in Middle East.
