ABSTRACT
The Libwa 4 well offshore the Democratic Republic of Congo was stimulated in November 1999 using an enzyme-based process that generated acid in-situ. The results to date have been excellent. Well tests as high as 759 BOPD have been recorded after the treatment compared to less than 100 BOPD before the treatment.
