Snubbers for MWD Electronics

Shock Absorbers for MWD Battery, Gamma, Pulser Driver and Directional Orientation Modules

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.

LORD offers a standard line of snubbers for MWD electronics, indcluding high temperature variants.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
