Abstract
This publication describes applying an external phased sensor array (e.g., ultrasonic phased-array sensor system) to non-destructively confirm the integrity of premium threaded tubular connections during Tubular Running Services (TRS) operations. The method uses ultrasonic wave transmission through the outside diameter of a box connection (female end) to generate a visualization of internally facing threads, seals, and adjacent critical features. The resulting indications can reveal gaps, unexpected metal accumulations, or other events consistent with galling and imperfect makeup conditions that may not be detectable using conventional torque-and-turn measurements. The technique enables rapid, non-invasive integrity confirmation suitable for use on the rig floor post makeup and/or in a bucking yard post-makeup as a quality-assurance (QA) gate. This check is intended to reduce the likelihood of premature connection failure, deferred production, and costly workover interventions on wells.
