A floating drift apparatus for verifying the inner diameter of tubulars as the tubulars are made up into a tubular string being run into a wellbore. A float section provides buoyancy to float the apparatus in fluid within the bore of a tubular, and a drift section has a drift element with a diameter substantially equal to the tubular inner diameter being verified, which may be the drift diameter. When running a tubular string, the apparatus is inserted into the bore of the tubular string, floating in the fluid. As joints of tubular are made up and run into the wellbore, the tubulars move downhole around the apparatus. Preferably, the floating drift apparatus can be visually detected. If an undersize ID is encountered, the floating drift apparatus will be pushed downhole and no longer visible; the operator can remove the undersize ID tubular from the string.

A borehole geometry sensor and running tool assembly includes a borehole geometry sensor sub-assembly configured to determine a borehole geometry of a wellbore. The borehole geometry sensor and running tool assembly also includes a running tool assembly that is initially detachably engaged to the borehole geometry sensor sub-assembly and configured to run the borehole geometry sensor sub-assembly into a borehole, and disengage the borehole geometry sensor sub-assembly after the borehole geometry sensor sub-assembly is run into the borehole. The borehole geometry sensor and running tool assembly further includes a pulse sub-assembly configured to supply power to the running tool assembly, and transmit data obtained by a borehole geometry sensor of the borehole geometry sensor sub-assembly.

The disclosure provides for a bottom hole assembly that comprises a housing and a caliper arm. The caliper arm is pivotally coupled to the housing at a hinge disposed within the housing, wherein the caliper arm is operable to rotate about the hinge between a first position within the housing and a second position external to the housing. The bottom hole assembly further comprises a linear actuator coupled to the caliper arm and operable to extend the caliper arm to the second position, wherein the caliper arm is biased to remain in the second position in contact with a borehole wall. The bottom hole assembly further comprises a sensor disposed within the housing and operable to monitor a position of the caliper arm.

A system and method for measuring an inside diameter of a pipe to determine if it exceeds a predetermined value using a plurality of fingers operatively connected to a spring. When in a fully extended position, the distance between opposite fingers is the predetermined value. The fingers are pivotable between a starting position, through the fully extended position, and to a failing position. In the starting position, an outer end of each finger engages an inside surface of the pipe to compress the spring. If the diameter exceeds the predetermined value as the system moves through the pipe, the pipe inside surface will no longer engage the fingers, which releases the spring causing the fingers to pivot to the failing position, where they remain until the system is removed from the pipe and manually reset.

Systems and methods include a system for deploying and using a customized logging-while-drilling (LWD) tool. A command is provided by a tool control system to a mechanical drive of a LWD tool to cause pads and caliper fingers of the LWD tool to extend radially, lock in place using a locking mechanism, and begin to capture downhole measurements while the LWD tool is deployed in a borehole of a well. Pressure pulse cycles produced by a series of distinct high and low flow rates by the tool control system are provided to create pulses to be detected downhole by pressure transducers. A measurement sequence for caliper and resistivity images is triggered by the tool control system. The measurement sequence is terminated by the tool control system to conserve energy.
