  • ACID TUNNELING BOTTOM HOLE ASSEMBLY AND METHOD UTILIZING REVERSIBLE KNUCKLE JOINTS
    Publication number: 20090114449
    Abstract: A bottom hole assembly connected to coiled tubing to create an acid tunnel in a wellbore formation. High pressure acid is pumped down the coiled tubing and out a nozzle located at the end of the bottom hole assembly. The bottom hole assembly includes a first reversible knuckle joint and a second reversible knuckle joint to properly position the nozzle against the wellbore and to allow the assembly to adjust its angle as it initiates and moves through the lateral tunnel. The two reversible knuckle joints increases the radius of curvature of the bottom hole assembly while providing a sufficient attack angle for the nozzle against the wellbore. The two knuckle joints may be adjusted in response to loads applied on the assembly as the assembly moves through the lateral tunnel.

  • Method of Using Water-in-Oil Emulsion to Remove Oil Base or Synthetic Oil Base Filter Cake
    Publication number: 20090114394
    Abstract: Fluid producing or injecting wells may be treated with a water-in-oil emulsion for the removal or inhibition of unwanted particulates, including pipe dope, asphaltenes and paraffins. In addition, such emulsions are effective in the displacement of oil base drilling muds and/or residues from such muds from wells. The emulsion may also be used to break the interfacial and/or rheological properties of oil base mud and synthetic oil base mud filter cakes, and act as a demulsifier to break the water-in-oil emulsion present in such oil base and synthetic oil base muds. The water-in-oil emulsions may optionally contain a dispersing agent as well as a surfactant.

  • Multiple dart drop circulating tool
    Patent number: 7520336
    Abstract: A downhole device used to divert fluid flow out of a work string. The downhole device may be located at any point along a work string at which it may be necessary to divert the fluid flow to the annulus. The downhole device may be activated and deactivated by inserting a single deformable dart into the work string. The device catches the dart blocking fluid flow through the work string. Increased fluid pressure activates the device, which diverts the fluid flow out of the work string into the annulus. A locating sleeve with a continuous j-track allows the device to be retained in activated position. The dart is adapted to deform under a predetermined amount of fluid pressure allowing the dart past the device and returning fluid flow through the work string. The downhole device may be activated multiple times without removing the downhole device from the wellbore.

  • Method of acidizing a subterranean formation with diverting foam or fluid
    Patent number: 7510009
    Abstract: A method of acidizing a subterranean formation with a diverting agent composed of a gelled or thickened viscoelastic foam or fluid generated from (i.) an amidoamine oxide gelling agent and (ii.) an acid or foam, water and/or brine. The gelled or thickened foam or fluid may be generated in-situ or introduced directly into the formation by mixing of the amidoamine oxide gelling agent and acid or foam, water and/or brine. As the acid spends, the acidizing fluid thickens. When the acid is further spent, the fluid viscosity declines eventually returning to a low viscosity state, allowing for easy cleanup. The process allows for selective acidizing of less permeable zones of the formation and more uniform stimulation of the hydrocarbon bearing formation.

  • Upper-completion single trip system with hydraulic internal seal receptacle assembly
    Patent number: 7506691
    Abstract: An upper-completion single trip system is described which includes a hydraulic internal seal receptacle assemble. The HISR assembly includes an overshot assembly selectively connected to a mandrel assembly. Once fully actuated, relative axial motion therebetween is allowed, which provides a spacer apparatus for the tubing above and below the HISR assembly. A shearable anchor latch as well as an indexing mule shoe are also provided in the HISR system, which allow multiple completion steps to be performed in a single trip. The HISR system is particularly well-suited for installation of permanent downhole gauges or intelligent systems—installations where rotation of pipe is prohibited. The system is also particularly well-suited for submersible pumps. A method of performing multiple completion activities in a single trip is also described.

  • STEP RATCHET MECHANISM
    Publication number: 20090065217
    Abstract: A step ratchet mechanism that allows for the incremental movement of an assembly that may be adapted to incrementally open or close an adjustable orifice. The step ratchet mechanism may be comprised of a modified body lock ring that permits incremental movement along a mandrel in either direction along the mandrel. The step ratchet mechanism may be actuated a designated distance by the application of pressure to the mechanism. The step ratchet mechanism may be ideal for using pressure to drive a downhole multi-position device. The modified body lock ring is adapted to both secure the mechanism at each set position as the mandrel is pumped down as well as allowing the mechanism to ratchet when the mandrel is pumped back.
