  • Method and apparatus to cut and remove casing
    Patent number: 5253710
    Abstract: An apparatus is established which facilitates the cutting and removal of well casing on a single trip into the wellbore. The apparatus is run into the wellbore on the tubing string and provides a rotatable sleeve including grapples adapted to engage the casing, and to facilitate removal of the casing. The apparatus also includes cutting assemblies coupled to the mandrel, which may be rotated so as to cut the casing, thereby facilitating removal of the casing through use of the grapples.

  • Apparatus for recovering a wellhead
    Patent number: 5146989
    Abstract: The invention relates to an apparatus for recovering a wellhead. The apparatus includes a housing, a latch, and a latch device actuator which are responsive to a force applied to the apparatus to separate the apparatus from the wellhead, which force will then cause the latch device to engage an external, rather than internal, profile of the wellhead so that the apparatus remains in engagement with the wellhead. The apparatus also includes a shaft which is capable of carrying a cutting mechanism to facilitate severing of the wellhead.

  • Flexible drill string member especially for use in directional drilling
    Patent number: 4811800
    Abstract: The invention relates to an improved drill string member having at least one spiral groove formed in its outside surface and incorporating a combination of engineering considerations and criteria such that the invention member will have an extraordinarily high performance capacity in directional drilling. The invention member can make bends in the well on radii as short as 25-50 feet and is particularly suitable for operation together with downhole motor driven bits.

  • Milling tool
    Patent number: 4717290
    Abstract: This miling tool for underground work consists of a tool body which has a plurality of cutter blades. Each cutter blade has a negative axial rake and an essentially constant negative radial rake. In addition, each cutter arm has a close packing of cylindrical cutting grade tungsten carbide inserts set at a lead angle of about 0 to 10 degrees. The inserts are also preferably vertically offset on adjacent cutting blades.

  • Reaming tool
    Patent number: 4618009
    Abstract: A narrow diameter reaming tool can ream a hole which is up to ten times the diameter of the tool. The cutting arms of the tool are of a type such that if there is an excessive load on an arm, the arm will fracture rather than bend.

  • Yield strength determination of ferromagnetic materials
    Patent number: 4335352
    Abstract: This invention pertains to two forms of verifier of the grade of oil field tubular goods. The first form can be thought of as a sorter in that it will indicate when a particular length of tubular goods is of a different grade than its companions in a lot. The second form will identify the grade of a length. Both forms depend upon magnetizing or inducing magnetic eddy currents in the pipe which are detected and handled by the invention circuitry to sort or to identify.

  • Casing slotter
    Patent number: 4119151
    Abstract: A drill string mounted tool for cutting a pair of spaced, vertical slots in well tubular goods comprising a pair of knives adapted to be swung outwardly, scissors style, by a piston member, which is in turn operated by well fluid pressure from the surface. Slot cutting is accomplished by vertically reciprocating the drill string carrying the tool with the knives extended.
