Abstract: Methods, systems, and apparatuses for determining the location or depth in a wellbore of a tubular string or downhole component is provided. One method may include placing a tubular string having a depth measurement module into a wellbore, the wellbore emanating radiation at at least one location along the wellbore and determining the location of the depth measurement module in the wellbore based on a correlation between a wellbore property that is a function of depth and a radiation intensity at at least one location within the wellbore.

Abstract: Systems and methods are described for non-invasively acoustically monitoring containers to distinguish gas contents from liquid contents. In some embodiments the container is part of a buoyancy tank (132) in a subsea pipeline network (102) used to transport production fluid from a subsurface wellhead (112) to surface facilities, and the systems and methods are used to detect water ingression into the buoyancy tank (132) and to transmit alert signals to the surface relating thereto.

Abstract: A sensor package may include a sensor housing unit and a first sensor that may acquire a first set of measurements within a first measurement range. The sensor package may also include a second sensor configured to acquire a second set of measurements within a second measurement range. The first measurement range and the second measurement range may include an overlapping range used to calibrate the first set of measurements, the second set of measurements, or both.

Abstract: Systems and methods are described for monitoring displacement on structural elements of subsea systems such as on components of a subsea pipeline network used to transport production fluid from a subsurface wellhead to surface facilities. The described techniques sense changes in displacement using a sensing blade, for example made of crystalline material such as sapphire, that is anchored to the structural element such that it is approximately perpendicular to the direction of sensed displacement. Displacement is sensed as bending of the sensing blade using one or more instruments fabricated on the blade. Robustness of design is in part provided by additional flexible non-sensing blades mounted in parallel to the sensing blade.
