High Torque While Drilling Ahead
The operator wanted to reduce the chances of high torque while drilling.

NRP Recommendation
WWT Non-Rotating Protectors (NRPs) were recommended with the goal of reducing the drilling torque. A total of 75 SS3-578 NRPs were installed at a frequency of one per joint on every joint. The figure on the right shows the recommended placement, where the shaded blue area represents the NRP placement at TD.

Estimated 23% Torque Reduction
A trip was made to install 75 NRPs to finish drilling the section to 12,680ft. After installation, the drilling torque immediately was reduced by 16% to 30kft-lbs.
WWT’s torque predictions were made with drilling parameters provided by the customer. Friction factors of 0.40 cased-hole, 0.50 open-hole with 25 klbs WOB were used in the analysis.?While these friction factors are high, they represented this well accurately prior to NRPs entering the hole.
The drilling torque plot, shows the actual drilling torque received from the customer as well as WWT’s predicted torque with and without NRPs. This data indicates the NRPs provided a 23% torque reduction at TD.

2 年These torque reduction devices represent a very useful and efficient aid in programs where torque and drag values represent high risk for the drill string, especially in directional profile wells. Personally I have used this brand WWT International in supervision of drilling operations. Success !!!
