ABSTRACT:
Well cuttings are disposed of by solidification by combining the cuttings with water and blast furnace slag, and injection of the cuttings, water and slag into an annulus surrounding a wellbore casing and solidifying the cuttings, water and slag. Solidification in blast furnace slag cement is inexpensive, and the blast furnace slag is compatible with both oil and water based drilling muds. Drilling fluids therefore do not have to be removed from the drilling cuttings prior to solidification in the wellbore annulus.
