ABSTRACT:
Drill cuttings are disposed of by injection into a subsurface formation by way of an annular space formed in a wellbore. 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 and a centrifugal pump for recirculating the mixture of cuttings and water (seawater) between the pump and the receiving tank. A discharge conduit is connected to the pump for moving the viscous slurry to an injection pump for high pressure injection into the formation.
