Compared with conventional hydrochloric acid treatments, microbial acid fracturing in carbonate reservoirs offers the technical benefits of a greatly increased fracture length coupled with the employment of non-corrosive, non-hazardous and environmentally friendly feedstocks. Following a discussion of the concepts underlying the technique, this paper describes in some detail the procedures, the results and the analyses of a first field trial performed in a carbonate reservoir in southern England in September 1991. |
