ABSTRACT:
Drilled cuttings are disposed of by solidification by drilling with a drilling fluid containing blast furnace slag, thereby producing drilled cuttings and other solid wastes, concentrating the wastes and then solidifying the concentrated wastes. Drilling wastes solidified by blast furnace slag are hard and unleachable and the blast furnace slag is compatible with both oil and water based drilling muds and drilled cuttings. Drilling fluids therefore do not have to be removed from the drilled cuttings prior to solidification in a mud pit.
