WedgeTail™ Roller Reamer improves drilling efficiency and enables longer runs in the Permian.
A major E&P operator drilling in the Delaware Basin of West Texas was looking for a solution to increase efficiency in its drilling program and looked to Reservoir Group to help them meet this challenge. By gaining an understanding of their well plan, Reservoir Group worked with the operator to determine that efficiencies could be gained from eliminating torque and drill string vibration.
It was determined that the torque and vibration was a result of the stabilizers, which historically have been installed in almost every drill string worldwide to eliminate drill string instability.
Reservoir Group Solution:
Reservoir Group worked with the Operator on their well plan and recommended the WedgeTail™ Roller Reamer, which provides the same benefits of a stabilizer in eliminating drill string interference; however, because it rolls against the wellbore rather than dragging against the wellbore, torque and vibration in the drill string are significantly reduced.
Due to the high-performance of the WedgeTail Roller Reamer, the operator ran an efficiency test on four wells to achieve baseline data; two were planned with under-gauge stabilizers and two with Full Gauge WedgeTail Roller Reamers.
