LORD® Snubbers are isolators for downhole tools. Snubbers act as MWD shock absorbers to protect MWD electronics from excessive shock and vibration. We knew there was a need for longer-lasting downhole tool isolators that can protect against shock and vibration, and we applied our aerospace technology to address the needs of the downhole community.
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:
