235385000, 235451000, 235492000

An apparatus for identifying oilfield tubular assets. A ring having an inner diameter is supported within the inner diameter of the tubular asset so that the inner diameter of the ring is substantially flush with the inner diameter of the tubular asset. At least one electronic circuit supported by the ring and adapted to transmit a unique identification code to a portable receiver. The portable receiver may have a display to communicate identity of the tubular asset. The portable receiver may display tubular asset maintenance and usage records stored at a central location or at the electronic circuit.

235375

An apparatus for identifying equipment, including the maintenance of usage histories for the equipment and recommending whether the equipment is to be used in a prospective application based on prospective application and usage history. A portable encapsulated passive circuit capable of transmitting an identification code is affixed to a piece of equipment. The circuit is activated by a portable reader which receives and decodes the identification code and transmits it to a central computer. The central computer verifies the reader and the existence of the equipment in a database and retrieves the usage history for the equipment. Based on the usage history, the prospective application and guidelines for usage of equipment, the computer determines the advisability of using the equipment in the prospective application and transmits the recommendation back to the portable reader.

175269

A borehole operating tool such as an underreamer or milling tool for performing borehole expanding or cutting operations in an oil well borehole, the tool including an elongated cylindrical housing having a main bore and side openings in which expandable arms are mounted for pivotal movement between closed and opened positions by a pivot pin; a piston element is mounted within the main bore of the housing for moving to an actuated position holding the expandable arms in an outer, expanded position; and a rotary fluid housing is mounted within each expandable arm about the hinge pin and includes a body nozzle for receiving fluid from the body and an expandable arm nozzle for directing fluid into a bore which extends through the expandable arm to thereby provide circulating fluid outwardly of the expandable arm in order to keep the operating outer end area of the expandable arm from becoming clogged.

29434

A drilling tool for use in drilling operations for providing shock absorption capability and lateral support to the rotary drill string. The telescoping axial load shock absorber is positioned immediately adjacent at least one lateral support provided by a reamer or stabilizer. The stabilizer preferably employs a removable fixed blade secured to the tool by an undercut groove. The roller cutter for a reamer is also mounted in a preferred unique manner with the mounting blocks secured in a recess having an undercut retainer portion in the event of bolting failure. The mounting's brackets may be formed integral of the tool body or attached by welding or the like. A preferred form of mounting a blade on a stabilizer tool is also disclosed.

A substantially homogeneous heavy wall drill pipe and its method of manufacture are disclosed. A cylindrical ingot is placed in a multi-hammer forging press to form the ingot into a drill pipe bar having a central protector portion and upper and lower connector sections each of larger diameter than cylindrical body sections of the drill pipe. Thereafter, the bar is straightened and upper and lower end connectors are machined. Threaded end portions are machined on the connectors and a bore is drilled through the drill pipe bar.

409143, 408 79, 408128

A trans-axial cutting apparatus used for cutting an inner surface of an opening formed within an object and accessible from outside the object. The apparatus comprises an elongate portable frame. The frame supports a cutting member on the first side and a stabilizing member on the second side. The stabilizing member is adapted to secure the apparatus during operation of the cutting member. The apparatus may be used to cut a counter bore, a longitudinal slot or groove at a desired depth, a helical slot or groove at a desired depth, or a slot or groove at a desired depth and along a desired path within the opening. Additionally, the apparatus is adapted to make any of the preceding cuts in a tapered or stepped manner within the opening of the object.
