Shock Absorbers for MWD Battery, Gamma, Pulser Driver and Directional Orientation Modules
With our isolators, you no longer have to compromise between reliability, durability and performance. First commercially introduced in 2012, LORD isolators have been outperforming any snubbers available on the market. In outcomes from customer and lab testing, our isolators have demonstrated significant reduction in shock and vibration, resulting in improved reliability.
LORD isolators can be designed to meet your unique downhole conditions:
- Extreme environments: high-temperature variants can withstand hot hole conditions
- High shock loads
- Broad frequency range isolation
- Custom connection geometry available

Mitigating Shock and Vibration in Downhole Drilling Operations
Shock and vibration are remarkedly different; but do you know how those differences affect your MWD directional drilling? This webinar is focused on reviewing the principles, fundamentals, and challenges of shock and vibration in a downhole oil and gas environment. In greater detail, shock and vibration theory, mitigation, and solutions will be discussed about how to successfully protect the MWD tool string from shock and vibration. Plus, hear a brief overview of the Parker LORD family of downhole isolators.
