  • Patent number: 8973652
    Abstract: The pipe wiper assembly of the present invention assists with wiping the pipe as the pipe is removed from the hole (“tripped out”). The pipe passes through the two pipe apertures of the pipe wiper assembly during the removal. Two upper containment arms adjust between an open position and a closed position within the housing to form the upper pipe aperture. The lower containment lip forms the lower piper aperture. The upper containment arms and lower containment lip partially enclose the housing to prevent the wiper from exiting the wiper storage. The containment arms slideably adjust to eliminate the need for hinges. The removal of the hinges provides for easier storage and transportation of the pipe wiper assembly. The removal of hinges also reduces manufacturing costs of the pipe wiper assembly.

  • Patent number: 8066060
    Abstract: During the production of crude oil, naturally occurring paraffin can be deposited on the inside surfaces of production tubing. These wax deposits reduce the cross sectional area of the tubing and can reduce or completely halt the flow of oil from the well. Currently there are many different methods employed in oil fields around the world to combat paraffin problems, but none are one hundred percent effective. When the available methods fail completely, costly removal and replacement of the tubing must be performed in order to resume oil production. The hot anti-wax knife tool provides a previously unavailable method of melting a hole through the paraffin deposits in the production tubing in order to restore production. The tool utilizes rechargeable batteries in a novel arrangement which provides sufficient power to melt through paraffin using a uniquely designed heating element and cutting head.

  • Patent number: 7621327
    Abstract: A tool is preferably landed in a downhole profile commonly found adjacent to seal bores. Once landed, preferably with coiled tubing, pressure in the coiled tubing triggers a switch to power a motor to rotate a polishing cylinder that features spirally wound vanes. A reservoir of resin or other repair material is connected to an injection pump to deliver the material as the vanes are rotating. The material exits between the vanes so that the vanes can spread it and work it into surface irregularities. After the material is sufficiently spread into voids and the requisite polishing completed, the seal bore is again ready to accept a tool in a sealed relationship.

  • Patent number: 7121336
    Abstract: A cylindrical brush for scrubbing the inside surface of a pipe is made of bristles attached to a springy helix. The diameter of the brush is greater than the inside diameter of the pipe. When the brush is pushed through the pipe the helix collapses and compacts the bristles to scrub the surface. When the brush is released in the pipe, the helix expands and spreads the bristles; thereby aiding in release of debris collected on the bristles during the scrubbing.
