Applications of acid fracturing technique to improve gas production in naturally fractured carbonate formations, veracruz field, mexico

摘要

This paper presents the results of successful applications of Acid Fracturing to increase gas production in mature carbonate fields in Mexico. Production comparisons show a substantial improvement in well performance following acid fracturing treatments. Six case studies are provided where a systematic methodology was emplooyed to correctly determine candidates, and treatments. The methodology discusses the use of a novel technique that consist in alternating stages of acid and a non reactive fluid.
