Case Study: a leading milling operating company saves 12 hours milling cement with SLB's DynaForce TT motor

Operator Saves 12 Hours Using High-Torque, High-Flow Motor While Milling Cement

Leading Milling Operating Company needed to mill a 2,200-ft section of incorrectly placed cement from inside a 4½-in completion liner in Saudi Arabia. SLB proposed using its DynaForce TT high-performance thru-tubing motor to deliver the high torque and flow rate needed for the job.

SLB deployed a 3⅛-in, 3.3-stage DynaForce TT motor with a Dyna-Drill NBR-HR elastomer, enabling the operator to mill and circulate the full 2,200-ft section in a single run. The work was completed 12 hours ahead of schedule, with no stalls and no damage beyond expected wear, saving 12 hours of rig time.
