The underground injection of drilling waste

The major oilfield processes that can influence the environment are drilling and production. Different materials are used in both processes, and waste is generated. Some of this waste can have significantly harmful effects on the environment ; thus, it is necessary to responsibly manage created waste. In virtually all cases, harmful effects can be minimized or eliminated through the implementation of proper waste management. The selection of the method to manage exploration and production (E&P) waste depends on laws and regulations, the ecosystem of the location where the operations take place and the cost-effectiveness of the selected procedures. The most widely used method for the disposal of most petroleum industry waste is underground injection, which enables the permanent disposal of waste slurry by injecting it into a suitable subsurface disposal zone. Performing underground waste injection in a safe, cost-effective manner requires experience, skill and resources.
