  • Patent number: 7134374
    Abstract: A safety cable cutter used for cutting a cable used in servicing an oil and gas well. A centrifugal arm roller and a guide roller are mounted on top of a frame. The cable is received on the rollers as the cable is lowered down a well bore. Mounted on ends of the centrifugal arm roller is a centrifugal arm attached to an arm coil spring. The coil spring holds the centrifugal arm next to the end of the roller. Opposite ends of a clamp attached to a cutter bar are slidably received in a pair of cutter bar guides. When the centrifugal arm roller exceeds a certain speed indicating a free fall of the cable, the bias force of the arm coil springs is overcome and the arms move outwardly. Contact ends of the arms engage the opposite ends of the clamp. The clamp and cutter bar are then moved outwardly and the cutter bar cuts the cable.

  • Patent number: 7096943
    Abstract: A method for growth of a hydraulic fracture or a tall frac is described wherein the tall frac is disposed next to a well bore using a sandpacked annulus. Also, a method for creating a permeable well bore annulus is disclosed. The method for creating the tall frac includes creating a linear-sourced, cylindrical stress field by maneuvering the intersection of two independent friction-controlled pressure gradients of a frac pad fluid. The intersection of these two frac pad fluid pressure gradients can be controlled when the frac pad fluid traverses along a well bore sandpacked annulus. The first pressure gradient is created by controlling the fluid flow rate and the consequent, friction pressure loss in the frac pad fluid flow through a portion of the sandpacked annulus, located above the top of the upwardly propagating tall frac hydraulic fracture. The first pressure gradient must be significantly greater than the average gradient of the formation, frac-extension pressure gradient.

  • Patent number: 7002350
    Abstract: A marine oil and gas exploration system used for measuring telluric currents as a natural electromagnetic energy source flowing beneath an ocean and sea floor. The marine exploration system includes a towed fish adapted for being pulled behind a survey ship. The coordinates of the ship and the towed fish can be controlled by a GPS satellite and time data. The fish includes an aerodynamic waterproof housing, somewhat reminiscent of a shape of a fish. Metal sheet electrodes of electric field sensors are mounted on the surface of a tubular nose extending outwardly from the housing. The electric field sensors are in direct contact with the sea water. Typically, the fish is towed approximately 100 feet above the sea floor. The positioning of the fish is maintained by the use of an acoustic “pinger” on the fish. The pinger transmits signals up a towed cable to the survey ship.
