Abstract: The invention relates to very precisely measuring changes in thickness of pipe walls to determine corrosion rate prior to any significant corrosion loss. The thickness is determined by ultrasonic testing where many measurements of the wall thickness are taken at the same spot by a fixed sensor and errors associated with noise and temperature changes are substantially eliminated. A highly sensitive receiver converts each reflected pulse to waves that are averaged with other pulse measurements. The resulting average wave is analyzed so that each waveform is analyzed to identify the extrema and inflection points of each reflected pulse. The resulting analysis provides a far more accurate determination of the time between reflected pulses. As a result, a far more accurate picture of corrosion at the location of the wall of the pipe can be determined within weeks with a high degree of confidence.

Abstract: A matrix production logging tool for measuring the temperature of produced fluids in a wellbore. Accurate production allocation to the pathways between the oil/gas well and the reservoir provides required data for the economic optimization of the techniques and procedures used to complete future wells. The low maintenance tool provides precise upstream, downstream and inflow temperature measurements of produced fluids within the wellbore.

Abstract: Methods and apparatus to reduce flow in front of the drill bit while milling improve milling debris size. Reducing flow on the drill bit face while milling allows the drill cuttings to remain at the drilling surface longer and reduce the size of the cuttings. The smaller cuttings increase the ease and speed of cutting removal.

Abstract: A method for joining coiled tubing is described. Coiled tubing joints using a magnetic pulse welder are described that retain the strength of the original tubing. This type of joint is useful for joining multiple coiled tubing sections or for removing and repairing damaged coiled tubing. Because the joint is as strong as the original tubing, these types of joints may be used when placing tubing in the well.
