  • Patent number: 8215396
    Abstract: An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured valving member with curved and flat portions that alternatively direct fluid flow through a bore or opening in the valving member via an inner channel or around the periphery of the valving member in an outer channel. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation.

  • Patent number: 8210282
    Abstract: Systems and methods for preventing slippage and rotation of components installed along a rotatable tubular shaft and/or in a tubular housing member during drilling operations are disclosed herein. The housing and/or rotatable shaft include a shoulder disposed proximate to one end. An adjustable member is secured proximate to the opposite end. One or more components are installed, covering a first portion of the surface between the adjustable member and shoulder. One or more spacing members are installed to cover substantially all of the remaining surface. The adjustable member is tightened such that the adjustable member and the shoulder apply a compressive axial load to the components and spacing members, causing frictional forces between adjacent objects greater than the torque acting on the housing and/or tubular shaft, causing each component to remain stationary with respect to the surface to which it is secured.

  • Patent number: 8186454
    Abstract: The present invention provides for pulsed power breaking and drilling apparatuses and methods. The present invention comprises two pulsed power systems coordinated to fire one right after the other. The first pulsed power system, comprising a spiker, may create a high voltage pulse that breaks down the insulative properties of the substrate and may create an arc channel in the substrate. It is designed for high voltage but low energy, at high impedance. The second pulsed power system, comprising a sustainer, is designed to provide high current into the arc, but at low voltage, thus better matching the impedance of the arc and achieving much more efficient energy transfer.

  • Patent number: 8176986
    Abstract: Retrieving a down hole tool at a lower end of a string of casing can be performed with drill pipe during a casing-while-drilling operation. The operator suspends the casing on a landing sub landed in a drilling rig floor opening. A string of drill pipe is lowered into the casing while the casing is suspended for engaging and retrieving the down hole tool. A spillage preventer in the landing sub prevents spillage of drilling fluid as the drill pipe is being retrieved. When circulation is desired, the operator secures a circulation tool to an upper end of the drill pipe, then lowers the drill pipe and the circulation tool to close off an upper end of an inner annulus between the drill pipe and the casing. A connection between the circulation tool and the landing sub allows the operator to reciprocate the casing.

  • Patent number: 8172006
    Abstract: The present invention provides for pulsed powered drilling apparatuses and methods. A drilling apparatus is provided comprising a bit having one or more sets of electrodes through which a pulsed voltage is passed through a mineral substrate to create a crushing or drilling action. The electrocrushing drilling process may have, but does not require, rotation of the bit. The electrocrushing drilling process is capable of excavating the hole out beyond the edges of the bit with or without the need of mechanical teeth.

  • Patent number: 8167049
    Abstract: Methods and apparatus for diverting fluids either into or from a well are described. Some embodiments include a diverter conduit that is located in a bore of a tree. The invention relates especially but not exclusively to a diverter assembly connected to a wing branch of a tree. Some embodiments allow diversion of fluids out of a tree to a subsea processing apparatus followed by the return of at least some of these fluids to the tree for recovery. Alternative embodiments provide only one flowpath and do not include the return of any fluids to the tree. Some embodiments can be retrofitted to existing trees, which can allow the performance of a new function without having to replace the tree. Multiple diverter assembly embodiments are also described.
