Annular injection offers an economical disposal mechanism for the oily cuttings and associated wastes generated from the use of oil-based muds in drilling operations. This disposal mechanism eliminates overboard cuttings discharges and, hence, removes much concern regarding the environmental impact of these wastes. Continued use of oil-based muds, which perform better than many water-based muds, is therefore feasible. Thus, BP Norway UA has been using the cuttings slurrying and injection process as the prime disposal mechanism for drilling wastes on the Gyda platform in the North Sea since July 1991. The paper describes compliance options, the injection process, injection history, fracture predictions, and results.
