oa Environmental Managment of Drilling Wastes

Drilling waste is a complex mixture of chemicals and cuttings use to meet the diverse requirements of drilling operation, and achieve well stability throughout exploration and production activities. The developments of best available technology (BAT) and best environmental practice (BEP) techniques have improved the environmental achievements of exploration and production activities. The cutting re-injection (CRI) technology is one of the latest waste disposal techniques. Slurrification is one of the integral parts of CRI for subsurface injection of drilling waste. In this paper, few of the major environmental management techniques for drilling wastes are highlighted including major aspects of CRI technology.
