CAHILL, Calvin D. |
There is disclosed a method and apparatus (10) for waste disposal by hydraulic embedment in a subterranean formation. The method comprises steps of drilling into stable geologic formations thousands of feet below ground, fracturing those formations, pumping a mixture of hazardous waste in solid, liquid, or sludge form and a selected transport medium into the fractured formations, and preventing migration of the waste. Although a suitable transport medium can be selected based on a number of factors, the transport media selected prevents migration of the waste by reacting chemically or to either heat of pressure or both to become highly viscous or solid. The method prevents waste migration by either pumping a fluid for sealing the fractured underground formation before the mixture is pumped or encapsulating the waste prior to mixture with the transport medium and injection into the fractured formation. Apparatus (10) for carrying out the method is also disclosed. |

Drill cuttings are disposed of by injection into a subsurface formation (12) by way of an annular space (26) formed in a wellbore (10). The cuttings are removed from the drilling fluid, conveyed to a shearing and grinding system that converts the cuttings into a viscous slurry with the addition of water. The system comprises a receiving tank (48, 50) and a centrifugal pump (56, 58) for recirculating the mixture of cuttings and water (seawater) between the pump and the receiving tank. A discharge conduit (76) is connected to the pump (56, 58) for moving the viscous slurry to an injection pump (78) for high pressure injection into the formation. |

JENNINGS, Alfred, Roy, Jr. |
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. |
