After repeated cement squeeze failures, casing patches were successfully used to stop casing leaks in a well operated in Indonesia. The Bunyu field, discovered in 1922, has 123 wells drilled with one dry hole in a complex series of channel sands interspersed with shales and coals. About 91 zones have been produced to data. Cumulative production is approximately 80 million bbl of oil. Although most wells produce with high water cuts, pressure maintenance and improving the sweep efficiencies across the channels by careful placement of injection points can substantially improve recovery.
