Disposal of Drilling Wastes in the Mountains

The foothills and mountain regions are extremely varied in soils, vegetation, climate and geology.  Oil and gas drilling wastes must be contained ana then dispose □ of, despite of this extreme environment.  An examination of three different drilling wastes indicates initially that salts are a main problem that have to be eliminated before any disposal can occur.  Proper storage of waste materials in tanks or lined pits is essential to prevent leakage of salts or organics into the environment.  Careful disposal planning before drilling begins can help mitigate any detrimental
environmental hazards when waste disposal occurs.  Land application of the waste at a pre-selected disposal site is a viable disposal alternative as the drilling wastes usually must be taken off lease in the mountain regions.  Research is progressing and is needed to help demonstrate what disposal options are possible.
