Patent ID: 7857077

Claim:
A system for producing a slurry of finely divided drill cuttings and a carrier liquid suitable for injection into a earth formation comprising: a) a tank means for containing carrier liquid and drill cuttings to be finely divided; b) a carrier liquid, having a surface, disposed in said tank means; c) drill cuttings to be finely divided disposed in said carrier liquid; d) a first submersible centrifugal pump means submersibly disposed within said tank means below the surface of the carrier liquid therein, said first submersible centrifugal pump having an inlet which is submersibly disposed within said tank means below the surface of the carrier liquid therein and a discharge which is submersibly disposed within said tank means below the surface of the carrier liquid therein, for creating recirculating flow of carrier liquid and drill cuttings through said first submersible centrifugal pump and within said tank means, without the necessity of piping external of said tank means; and, e) means for withdrawing a slurry of finely divided drill cuttings and carrier liquid suitable for injection into an earth formation from said tank means.
