ABSTRACT:
A method for disposing of drilling wastes where an aqueous saline solution is used to disperse a drilling fluid or mud. The saline solution containing the dispersed drilling fluid or mud is injected into a disposal well or high permeability oil depleted zone. An interval of the formation adjacent to the disposal well is hydraulically fractured so as to allow continued injection of the solution containing the drilling fluid or mud at substantially low pressures. Hydraulic fracturing is used to re-establish communication with a disposal zone whenever a "skin" builds up due to filtration of the solids from the injected drilling fluids or muds.
