Abstract: A method and an arrangement for visual inspection and logging of oil and/or gas well pipes are provided. The arrangement comprises an inspection tool arranged to record, during the visual inspection, a plurality of images by recording means comprising gat least one fisheye lens. The method comprises guiding the inspection tool in an oil and/or gas well pipe, and to record a plurality of fisheye images during the guiding.
Abstract: The present disclosure relates to an inspection assembly (10) for inspecting the interior of a pipe (12). The inspection assembly (10) comprises a sensor assembly (20) adapted to receive a sensor signal and a housing (22) within which the sensor assembly (20) is at least partially arranged. The inspection assembly (10) comprises a seal (24) at a first housing end (31). Moreover, the inspection assembly (10) is adapted to assume a transport condition in which the sensor assembly (20) is positioned in a first position in the housing (22) and in which the seal (24) is closed. The inspection assembly is further adapted to assume an inspection condition in which the inspection assembly (20) is positioned in a second position, closer to the first housing end (31) as compared to the first position, and in which the seal (24) is open.
Abstract: An inspection tool for inspecting oil and/or gas production and/or injection wells and pipes is provided. The tool comprises at least an image sensor, one or more processors or chips and one or more power supplies. The tool further comprises at least a first and a second chamber being insulated from each other. The first chamber comprises the image sensor and is provided with one or more passive cooling means, and the second chamber comprises the one or more processors and is provided with one or more active cooling means. Further, a method for cooling such inspection tool is provided.
Abstract: A sensor cover (1) for an inspection assembly (3) is provided. The inspection assembly (3) is adapted to inspect the interior of a hollow member (5). The sensor cover (1) comprises a delimiting means (13.1, 13.2) configured to at least partially delimit a sensor cover volume (11.1, 11.2). The delimiting means (13.1, 13.2) comprises a flexible material and is configured to permit a modification of the sensor cover volume (11.1, 11.2) such that at least a portion of said delimiting means (13.1, 13.2) is closer to a portion of said hollow member wall (7) after said modification than before said modification to thereby enable said sensor signal to be transmitted from the hollow member wall (7) to the sensor (9). The present disclosure also relates to inspection assembly (3), a use of an inspection assembly (3), and a method (100) for inspecting the interior of a hollow member (5).
