Disclosed herein are measuring assemblies including a measuring assembly for measuring one or more dimensions of a pipe that has an inner surface and an outer surface, which measuring assembly may include: a cylindrical housing; a first probe rotatably coupled to the housing; and a second probe rotatably coupled to the housing and capable of being disposed inside the pipe.

Tools and methods are described to measure dimensions of wellbores. Downhole caliper tools include a downhole collar and an uphole collar having a running position and a sensing position. The uphole collar is farther from the downhole collar in the running position than in the sensing position. A caliper sensor assembly includes: a sensor module defining tracks extending parallel to an axis of the caliper tool, the sensor module positioned towards an uphole end of the caliper tool relative to the uphole collar; and a caliper disposed between the downhole collar and the uphole collar including: a flexible mesh extending from the downhole collar to the uphole collar. Movement of the uphole collar from the running position to the sensing position axially compresses and radially expands the flexible mesh. The annular sensor module can measure dimensions of the flexible mesh relative to the axis of the caliper tool.

A computer-implemented method includes monitoring, by a computing device, data measurements associated with a bottom hole assembly (BHA), and detecting, by the computing device, a plurality of possible tight instances. An individual possible tight spot instance is detected based on a data measurement satisfying a threshold.

A plug gauge includes a housing defining an internal volume and a longitudinal axis AH. The housing includes an opening into the internal volume. The plug gauge also includes a contact element at least partially received in the opening. The plug gauge further includes a plunger at least partially received in the internal volume. The plunger is biased into engagement with the contact element to urge the contact element radially outward from the housing through the opening. The plug gauge additionally includes a sealing member between the contact element and the housing.
