<p>A method and associated apparatus (10) for measuring geometry of a wellbore, the method including locating a measuring apparatus (10) within a tubular (30) that is located within the wellbore (2); contacting an inner wall (32) of the conduit with at least one sensor (40); transmitting one or more signals through the conduit (30) towards a wall (4) of the wellbore (2) that surrounds the conduit (30); detecting one or more signals reflected back from the wall (4) of the wellbore (2); and determining the geometry of the wellbore (2) behind the conduit (30) from the detected signal. Advantageously, the method comprises determining one or more properties indicative of the geometry, e.g. size, shape or dimensions, of the wellbore or wellbore wall. In embodiments, the method and apparatus detect or determine the extent of a device or structure provided between the conduit and the wall of the wellbore.</p> |
