ABSTRACT:
A drill cuttings slurry process system is disclosed for defluidizing earth drill cuttings, thereby extracting valuable drilling additives and returning them to the drilling system while producing a dense, drier material which may be discharged directly in the environment at or near the well being drilled or chemically treated for distillation and/or better dissolution into the environment, thereby reducing, cost in transportation and environmental treatment chemicals thus reducing environmental contamination. The system comprising a cuttings press having solids/fluids separation a dryer and/or a retort for flashing off any residual petroleum residue and moisture, a fines grinder and a chemical injection system. The retort including an analyzer system for weighing and determining rate of throughput and analyzing the cuttings for residual petroleum residue content prior to discharge to environment or further refinement prior to reinjection into the well or transport to environmental depository sites.
