A method and associated system for determining geometry of a deformed pipe or conduit or wellbore, the method comprising: collecting, determining and/or receiving measurement data indicative of a plurality of radii of the pipe or conduit using equipment, such as a calliper tool 5, centred in the pipe at two or more points a known distance from the measurement point but not at the measurement point itself; selecting a deformation type and/or deformation model; processing (processing unit 50) the measurement data to determine one or more geometrical properties of the pipe or conduit, the geometrical properties being indicative of, or associated with, one or more deformations, shapes or profiles of at least part of the pipe or conduit; and guiding and/or constraining at least a part of the processing of the measurement data using the selected deformation type or model and/or fitting the selected deformation model to the measurement data. The specification teaches and claims, in a separate invention, a method of determining clearance and/or maximum and/or diameter limits for a tool, load or other device to be inserted into a pipe, conduit or other structure. |
