Abstract: An apparatus for inspecting integrity of a multi-barrier wellbore is described. The apparatus includes at least one source to generate radiation to impinge a target volume of the wellbore. The apparatus includes a source collimator having a plurality of alternating blocking channels and passing channels to direct radiation to impinge the target volume, such that the radiation directed from each passing channel forms a plurality of field of views extending radially into the target volume. The apparatus further includes at least one detector to receive backscatter rays arising from each respective field of view from the plurality of field of views and to generate an image representative of an inspected portion of the wellbore. The apparatus is useful for inspecting very small volumes in the multiple barriers of the wellbore and determine the integrity of the wellbore based on the different densities in the image of the inspected portion.

Abstract: A measurement system includes a cable having a length, a light source, at least one detector, and at least one processor. The light source is operably coupled to the cable and is configured to transmit an optical signal to the cable. The at least one processor is operably coupled to the cable and configured to: receive a scattered signal from the cable responsive to the optical signal transmitted to the cable; map the scattered signal to the length of the cable; and de-convolve a spatial averaging effect of the scattered signal using a weighting profile corresponding to the light source and the cable to generate a distributed property profile defined along the length of the cable.

Abstract: A fluid sensor cable assembly and method uses one or more conductive bodies extending along an elongated core body for conducting a heating current to heat the cable assembly. The one or more conductive bodies also are configured to conduct an interrogation signal and to conduct reflections of the interrogation signal. One or more optical fibers extend along the length of the core body and include temperature sensitive elements at different locations along the length of the core body. The temperature sensitive elements measure heat flux out of the cable assembly at the different locations subsequent to heating the cable assembly and communicate the heat flux to a computer acquisition system.
