WWT ME 11752: Significant Torque Reduction in Directional Well

Executive Summary

High torque was expected on a directional well for a major ME operator. WWT’s Non-Rotating Protectors

(NRPs)were installed for torque reduction in the 8.5 in. section and resulted in 18% on bottom and 24% off bottom torque reduction.

NRP Performance

WWT NRPs were installed to cover the build section of the well and covered from 752ft to 7,066ftMD when the bit was at TD.WWTSS3-550 model NRPs were installed at a frequency of one per joint to provide tool joint stand off with the casing in the area of concern, and effectively reduce torque.

NRP Performance

 • Backmodels showed FFs 0.27 CH and 0.35 OH matched actual On-bottom and Off-bottom torque.

 • Average ROP fluctuated between 70 ft/hrand 100 ft/hr throughout the section  

• RPM remained steady throughout the section at around 120 c/min.

• WWT NRPS yielded: 18% Reduction for On-Bottom Torque 24% Reduction for Off-Bottom Torque from back modeled simulations
