Abstract: A system for determining a stuck point of a pipe positioned within a wellbore includes a tubular housing and a sensor array positioned within the tubular housing. The system also includes ferromagnetic flux collectors and flux concentrators on either side of the sensor array. The flux collectors collect a magnetic flux that has been written to a portion of pipe. The flux concentrators intensify the flux to improve measurements of the flux that are acquired by the sensor array.

Abstract: A system for determining a stuck point of a pipe positioned within a wellbore includes a tubular housing and a sensor array positioned within the tubular housing, the sensor array arranged at a first end. The system also includes a first magnetic source positioned within the tubular housing, the first magnetic source arranged at a second end. The system further includes a second magnetic source positioned within the tubular housing, the second magnetic source arranged between the sensor array and the second end. The first magnetic source and the second magnetic source have a different magnetic field source.

Abstract: Embodiments relate to a system and method for detecting and remediating selective seam weld corrosion in conduits such as steel pipes that transport oil and gas products. In particular, a probe detects magnetic flux leakage in at least two orientations. Anomalies in the conduit are then identified and assessed for selective seam weld corrosion based on factors that include the magnetic flux leakage detection and the depth of the anomalies. For certain categories of assessed anomalies, the corresponding portions of the conduit are selectively remediated in accordance with these factors.

Abstract: A radiation detector 10 has a base 12 and a window 16 that define a vacuum chamber 20. Within the vacuum chamber 20 is a temperature controlled filter 32 and a focal plane array (FPA) 22 defining a gap h therebetween. The filter 32 is heat sunk to a readout integrated circuit (ROIC) 24 and thermoelectric elements 28 to inhibit heat transfer from non-scene sources 38, 40 to the FPA 22. The temperature controlled filter 32 may also incorporate a bandpass filter to reflect all sources of radiation not within the desired wavelength region of interest. The temperature controlled filter 32 is maintained at substantially the same temperature as the FPA 22.

Abstract: A jar ticket includes a ticket body having first, second and third panels wherein the third panel is folded onto the second panel and the second panel is then folded onto the first panel to constitute a folded section of the ticket body. A wrapper body is then folded around the ticket body folded section. The wrapper body includes first, second and third panels. The second panel of the wrapper body is brought adjacent a first side of the folded section of the ticket body and the first and third panels of the wrapper body are folded over a second side of the folded section of the ticket body. A first layer of adhesive is disposed between the first and third panels of the wrapper body and a plurality of spaced perforations extend through the first and third panels of the wrapper body. Such a jar ticket has enhanced security. A jar ticket manufacturing machine for such a jar ticket is also disclosed.
