Thruster™

Overview

The Thruster provides a consistent force to the bit by balancing hydraulics (differential pressure) and mechanics (weight on bit). This balance provides smooth energy transfer to the bit, even in the most erratic of scenarios.

Challenge

High shock and vibration, particularly in increasingly long laterals, can rapidly increase drilling costs. However, using aggressive bits to increase ROP and obtain quick performance can result in damages and associated trips for new bits and BHA components.

Application

The Thruster reduces shock and vibration to ensure the reliability of BHA components and bits. It provides a consistent force to the bit by balancing hydraulics (back pressure below tool) and mechanics (weight on bit). This balance provides smooth energy transfer to the bit – even in erratic circumstances.

Results

As operators continue to push limits in extreme conditions, TAQA’s Thruster works to reduce risks. We analyze the BHA, well profile and drilling performance requirements and discuss specific objectives with your drilling team. This communication and bespoke approach ensures optimal performance from any mechanical thruster.
