ABSTRACT:
A method and apparatus for handling, processing and disposing the drill cuttings removed from the drilling mud of oil and gas well drilling rigs is disclosed. The apparatus and method utilize a shaker for separating drill cuttings from the mud, conduit for transporting the drill cuttings so separated to an extruder where the separated cuttings are compacted into a plurality of discrete compacted pellet-like bodies. The pellets substantially reduce the volume of drill cuttings. There is also a substantial reduction in the retained fluid volume, including the volume of environmentally harmful fluids, after the cuttings are compacted. Once extruded into pellets, the pelletized drill cuttings are transported to a desired end location that may include dumping the pellets offshore.
