  • Patent number: 8220178
    Abstract: A liquid solid separator utilizing inductive heating. An electrically conductive scroll conveyor is contained within a non-magnetic and non-conductive housing under vacuum. A moveable alternating electric coil is disposed around the housing. The scroll pulls the solids through the housing. Operation of the coil heats the scroll which heats the solids. The vacuum lowers the boiling point of the liquids, and they are vaporized at a relatively low temperature. The vapors are condensed and collected. Because of the low temperatures, the separated liquids are less likely to deteriorate during separation, facilitating recycling. Thermocouples and a computer track the internal temperature of the separator and coordinate the position of the coil to maintain the desired temperature. The housing is provided with a heat insulating outer layer and the interior of the scroll is pressurized with nitrogen. The separator surfaces exposed to the atmosphere are maintained at or below 150° F.

  • Patent number: 7562725
    Abstract: A drilling unit containing a combined pilot bit and reamer. The drilling unit includes a housing containing a mud motor and a pilot bit extending from its distal end. A reamer is mounted to the housing. The mud motor turns the pilot bit while the reamer is turned either by the mud motor or as the drill string is rotated from the surface. The well bore is drilled and reamed in one pass. By positioning the reamer between the pilot bit and the mud motor, the mud motor must only pass through the larger reamer bore rather than the smaller pilot hole. This will allow larger mud motors to be used than would otherwise be possible. In one embodiment, the pilot bit is offset relative to the center of the end of the drill housing, providing increased tangential speed at the point of impact between the pilot bit and formation.

  • Patent number: 6305881
    Abstract: An oil drilling barge stabilization system and method provide that an array of substantially vertically-oriented piles is formed in the sea bed to a depth beneath the sea bed that finds solid support. A barge is towed into position over the array of piles, and the barge is partially flooded with ballast to lower it in the water so that a set of cylindrical tubes is positioned to surround top ends of at least some of the piles. Air is then forced into the tubes to force the water out the bottom of the tubes, to create a dry environment for workers. Workers weld the tubes to the piles. The air pressure is removed from the interior of the tubes so that water may again flood the bottom of the tubes. The joints between the tubes and piles secure the barge to the array of piles, even in the face of varying tides, currents, and ice flow conditions. The barge may be used to support oil rigs and a variety of other support facilities.
