(2023043) Measuring Wellbore Friction During Workover Operations (Update)

The workover process provides a unique opportunity to directly measure wellbore friction as the rods effectively probe out the wellbore. Measuring this effect is challenging as no sensor exists that can provide an accurate, high resolution, high frequency measurement during the entire workover process. This presentation will analyze data gathered from a custom load & position sensor placed in-line with the rod-hook during the workover process. The normal rig crew process was unaltered beyond the initial installation and removal of the sensor. Detailed sensor measurements are available for each stroke of the rig and processed to determine the overall behavior of friction acting on different lengths of rod in the hole.
