Abstract
Devices and methods are described for evaluating tubulars installed in a wellbore, which permit detection of wellbore construction errors. Errors in the hardness or grade of the material installed, e.g., in critical wellbores, could potentially affect the integrity of the wellbore and lead to catastrophic effects with respect to well control, pipe connection failure while running casing down-hole, or pipe body failure due to buckling or axial/triaxial failure during stimulation and production. Once tubulars are installed, the devices and methods permit testing the hardness of the steel or other material forming the tubulars. Determining the hardness of the tubulars may provide assurances or indications that remedial action may be appropriate to secure the wellbore. The devices and methods can be implemented to deliver a down-hole Rockwell hardness test in connection with logging while drilling technologies, with wireline tools, or in connection with other deployment mechanisms.
