OVERVIEW

HFTO & Bit Impact Arrestor

The Mitigator™ is a patent pending torsional damper that limits HFTO, reduces the occurrence of stick/slip, and improves bit durability. By rapidly deflecting and recovering from rotational shock events, the Mitigator smooths torsional impacts in the BHA and at the Bit without limiting depth of cut. Drilling performance can be elevated while maintaining bit and BHA durability to hit target depth.

HFTO Mitigation

High speed vibration, also known as High Frequency Torsional Oscillation (HFTO) is a drilling dysfunction that flies under the radar of most sensors and contributes to a wide range of performance limitations. The chart below shows how much damaging shock the Mitigator is capable of absorbing during a 30-minute interval of drilling.

Bit Impact Reduction

The Mitigator has proven to reduce impact loading at the bit which leads to direct improvements in cutter life, higher average penetration rates, better dull conditions, and a reduction in DBRs. The chart below compares torsional shock levels at the bit in back-to-back wells, illustrating the benefit of having the Mitigator in your BHA.
