Abstract: A flow meter for measuring the flow of fluid through a pipe. The flow meter has an elongate member attached to an interior surface of the pipe. The elongate member has a leading end, a trailing end, a longitudinal axis, a first side, and a second side. The first side extends from the leading end to the trailing end and defines a cylindrical cross-sectional shape with a radius of curvature corresponding to the radius of curvature of the pipe and extending along an arc of less than 180 degrees. The second side extends from the leading end to the trailing end and is exposed to the interior of the pipe. The second side forms a constriction in a cross-sectional area of the pipe. Pressure sensors determine a pressure differential caused by the elongate member which is used to determine the volume of fluid flowing through the pipe.

Abstract: 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.

Abstract: 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.
