CASE HISTORY: WWT NRPs Help Drill The Longest Lateral in The Lower 48

Executive Summary

WWT International was approached by an operator to utilize WWT Non-Rotating Protectors (NRPs) to reduce torque in the drilling of a directional well's 8-1/2 inch section. This specific section was significant as it marked the longest lateral in the Lower 48, running from 7,635 ft to 31,962 ft TD.

Challenge

The drilling operation required precision and efficiency to cover the areas of highest side forces in the vertical and curve into the open hole.

Solution

• Deployment of NRPs: 267 x SS3-550 NRPs were installed at one per joint on 5-1/2” drill pipe (DP).
• Placement: NRPs were placed 5 ft above the tool joint, creating a standoff that reduced friction and torque.
• Torque Reduction: The torque back models revealed a 13% reduction at well TD.

Performance

• Torque Reduction: 13% reduction in torque.
• Pipe and Casing Protection: Ensured integrity of both the drill pipe and the casing.
• Maintained High ROP: Achieved 250+ average ROP throughout the 24,166’ ft lateral.
• Duration: All 267 NRPs were in good condition after a maximum of 8 days downhole.
• Fast Installation and Removal: Both operations were performed offline of rig activity, causing no additional rig time.
• Collaboration: Success was credited to teamwork & communication, vital in challenging ERD wells.

Impact

• Record-Setting Well: WWT NRPs helped in drilling this record well quickly and efficiently.
• Extended Use: Seeing the benefits, the operator continued to use NRPs on other projects with slightly shorter laterals.

Conclusion

The deployment of WWT NRPs not only aided in achieving a record-setting well but also showcased the essential features and benefits of the technology. With tangible results in torque reduction, casing protection, and maintained high ROP, WWT International has proven the robust design and efficiency of its NRPs. The success of this project underlines the power of teamwork and innovation in overcoming challenges in the drilling industry.
