Abstract: A process for removing free liquids from oil base mud contaminated drill cuttings waste. A process is described wherein a high gravity centripetal separator and low temperature thermal process are cooperatively used to enhance the mechanical and thermal separation methods, resulting in improved efficiency of the hydrocarbon and water removal process. A process is also described wherein the oil base mud contaminated drill cuttings waste is heated to strip volatile constituents and excess water from the oil base mud contaminated drill cuttings to further enhance the mechanical and thermal separation methods resulting in improved efficiency of the hydrocarbon and water removal process. A less expensive process is also described where the oil base mud contaminated drill cuttings waste is heated to strip volatile constituents and excess water from the oil base mud contaminated drill cuttings to further enhance the recoverable liquids phase during mechanical separation. A conventional stripping process for oil base mud is also utilized.

Abstract: A gas tight shale shaker for enhanced drilling fluid recovery and drilled solids washing. A process and apparatus for liquid phase-solid phase separation of oil base drilling mud-containing drill cuttings is described including flowing the drilling mud-containing drill cuttings over a vibrating screen bed to cause a least a portion of the drilling mud to pass through the screen bed and the drill cuttings to remain on the screen bed. A diluent is added to the oil base drilling mud containing drill cuttings prior to flowing the drilling mud containing drill cutting over the screen bed. The entire process is performed in a gas-tight environment preventing escape of diluent from the process into the external atmosphere and preventing introduction of gases into the process from the external atmosphere.

Abstract: A hermetically sealed horizontal washing decanter centrifuge for enhanced drilling fluid recovery and drilled solids washing. A process and apparatus for liquid phase-solid phase separation of oil based drilling mud-containing drill cuttings is described including flowing the drilling mud-containing drill cuttings into a horizontal washing decanter wherein the stresses imposed within the decanter act as a wash as the diluent and oil based drilling mud move away from the drill cuttings. Diluent is added prior to flowing the drilling mud containing drill cutting to the hermetically sealed horizontal washing decanter centrifuge. The entire process is performed in a gas-tight environment preventing escape of diluent from the process into the external atmosphere and preventing introduction of gases into the process from the external atmosphere.

Abstract: A process for removing volatile diluent(s) from processed solids, generated from unstabilized drilling waste being washed in a diluent/solvent wash process. The process describes the use of hot water to deliver quality heat energy to the processed solids phase, evaporating the diluent and at least partially removing chlorides or other soluble or insoluble contaminants in the process, resulting in enhanced efficiency of diluent and contaminant recovery, for example, as a result of the near infinite surface area of water, among other things.

Abstract: Auger conveyors most commonly employed in industries where the horizontal and/or vertical transfer of solids or semi-solid materials is required. Auger conveyors employ a rotating helical screw blade, commonly known as fighting, which rotates about on an inline axis within an inline conduit. Described herein is an auger conveyor which does not need to follow the traditional rule of rotating about on an inline axis. A flexible wire rope shaft is employed to rotate about on an infinite number of axes thereby facilitating an auger conveyor connected to the flexible wire rope shaft through buttons, to traverse a non-linear path.

Abstract: A method and apparatus for removing low micron solids from a mixture of recovered oil based drilling fluid and low micron solids and diluent. A gas tight clarifier device that is designed and constructed for this purpose in a gas-tight manor so to ensure vapour cannot escape the separation process, and foreign oxygen cannot enter the process under normal operating conditions.

Abstract: A transport vessel and method specifically adapted for safely and efficiently transporting and removing liquid containing unstabilized drill cuttings. Typically drilling waste is stabilized using binding agents like fly-ash, liquids absorbing pellets or sawdust. In many jurisdictions binding agents are required to stabilize the drilling waste prior to transport. A sealed transport vessel is described herein which is specifically sized and positioned over a set of axels so as to provide for safe, non-spilling transport. In addition, the bottom section of the vessel additionally contains one or more heating elements capable of raising the temperature of the drill cuttings at or near the bottom section of the container to a free flowing state for easy removal, even in cold/adverse weather conditions.
