Threlix®

Overview

TRANSFORM CHALLENGES INTO TRIUMPHS WITH THRELIX®

TAQA presents Threlix®, a patented technology designed to assist operators in mitigating drilling dysfunctions while drilling with rotary steerable systems (RSS). By balancing downhole torque against downhole weight on bit (WOB), Threlix™ ensures a smooth and consistent depth of cut at the drill bit, effectively eliminating erratic torque, stick-slip, and HFTO (high-frequency torsional oscillation) which can lead to bit and downhole tool DBR’s, Tool failures and costly trips out of the hole.

Challenge

When encountering excess torque during drilling operations, Threlix® instantly adjusts its length to maintain a consistent depth of cut at the bit interface preventing stick-slip scenarios, ensuring optimal drilling progress leading to exceptional performance, reduced damages, and minimized section times.

Application & Results

Threlix® is engineered with a proprietary helical spring that facilitates both compression and extension, enabling it to meet any drilling application. Furthermore, its 100% sealed spring and spline sections significantly enhance downhole reliability and performance, eliminating the need for costly post-run maintenance and reducing associated risks.
