An investigation was made of several possible ways that activities associated with the production of oil and gas can contribute to the pollution of the environment. The study indicated that possible polluters include the following: drilling fluids, drilling muds, well treatment chemicals, corrosion inhibitors, friction reduction additives, crude oil, natural gases, oilfield brines, abandoned disposal ponds, and inadequate subsurface disposal wells. It was recommended that the mineral wealth should be extracted from oilfield brines to help pay disposal costs and conserve valuable natural resources.
