Abstract: Downhole imaging systems and methods are disclosed herein. An example method includes projecting flushing fluid into an optical field of view of an imaging system disposed on a downhole tool. The example method also includes directing a pattern of light onto a target in the optical field of view via a light source of the imaging system and determining three-dimensional shape information of the target based on the light directed from the target and received via an image detection plane of the imaging system. The example method further includes determining a characteristic of the target based on the three-dimensional shape information.

Abstract: A technique facilitates an improved operation of a tool, such as a downhole tool. The tool is operated in a manner which provides a dynamic or cyclical loading. The dynamic or cyclical loading of the tool is sampled by a suitable sensing system at a frequency greater than the frequency of the dynamic or cyclical loading to collect detailed data on the dynamic or cyclical loading. The data is used to adjust the tool in a manner which improves operation of the tool. One technique for adjusting the tool is changing the dynamic or cyclical loading of the tool by adjusting the frequency of the dynamic or cyclical loading.

Abstract: A technique facilitates evaluation of pipe. A sensor is positioned to examine a pipe and to obtain data on the pipe. The data obtained is analyzed on a processor-based system and compared to predetermined defect data. If the data obtained by the sensor sufficiently matches predetermined defect data, a defect is determined to enable performance of an appropriate action with respect to the pipe.

Abstract: A system and method for repairing and/or joining together multiple lengths of tubulars using friction stir joining, and a system for manipulating the tubular so that friction stir joining may be performed while the tubular is on a reel and/or at a field site.
