A hang-off tool for supporting a tool inside a tubular member includes a logging string configured to generate logging data, a computing system coupled to the logging string and configured to communicate the logging data to another tool, and a radially expandable member having a retracted position and an expanded position. The radially expandable member is configured to engage a radially-increased profile of an inner surface of the tubular member in the expanded position to support the hang-off tool. The radially expandable member is also configured not to engage the radially-increased profile in the retracted position.

Embodiments of the present invention generally relate to methods and systems for logging through a drillstring. In one embodiment, a method of logging an exposed formation includes drilling a wellbore by rotating a cutting tool disposed on an end of a drillstring and injecting drilling fluid through the drillstring; deploying a BHA through the drillstring, the BHA including a logging tool; forming a bore through the cutting tool; inserting the logging tool through the bore; longitudinally connecting the BHA to the drillstring; and logging the exposed formation using the logging tool while tripping the drillstring into or from the wellbore.

Through drillstring logging systems and methods

An optical inspection instrument includes a housing configured to move along the interior of a pipe string in a wellbore. The pipe has a cutting structure at its bottom end. The instrument includes a probe extending from a bottom end of the housing. The probe has an output from a light source and a light input to a video camera. The probe has a diameter selected to enable extension through an opening in the cutting structure. A method for inspecting a wellbore includes moving an instrument through an interior of a pipe string in the wellbore. The pipe has a cutting tool at its lower end. At least part of the instrument is moved outside the bottom end of the pipe through a port in the cutting tool. Optically transparent fluid is moved into the wellbore proximate an end of the instrument outside the pipe string. Objects proximate the fluid are inspected.

Through-mill wellbore optical inspection and remediation apparatus and methodology

A method for inserting a tool into a wellbore includes uncoiling a coiled tubing into the wellbore to a selected depth therein. When the tubing is at the selected depth, the tubing is uncoupled. A tool is inserted into the interior of the tubing. The tubing is reconnected, and the tool is moved along the interior of the tubing.

A deployment device for controlling rate of movement of an instrument inside a conduit includes a mandrel having a coupling to affix the deployment device to the instrument and a controllable brake disposed in the mandrel, the brake controllably actuatable to maintain the mandrel and instrument at a selected speed within the conduit.
