Axial Isolator

MWD Shock Absorber

MWD Shock and Vibration Mitigation

LORD® Axial Isolators, or MWD shock absorbers, are specifically designed to protect Measurement While Drilling (MWD) electronics from axial shock and vibration. Our field-proven axial isolator can extend the life of MWD tools and protect downhole electronics in a broad range of operating conditions by significantly reducing the magnitude and quantity of shock events.

Reduces Axial Shock Events by 70-80%

Axial isolators protect MWD tool strings from shock and vibration, offering improved reliability, durability and service life in the toughest conditions

Improves MWD Reliability

Customers report staying in the hole longer in their toughest wells from North Dakota to West Texas

Field-Proven

Over 500 units fielded since 2015

Simple is Better

No oil fill required

This product utilizes non-linear elastomer spring/damper elements, which improves reliability and shortens maintenance cycles versus conventional metal spring with fluid compensation alternatives

Centralized Axial Isolator

While an axial isolator provides excellent protection against shock and vibration, it also adds three feet of length to the tool string, creating a longer section without lateral support. Bolt-on fins serve as an optional upgrade to our standard axial isolator, providing additional lateral stabilization to the tool string, which reduces wear on the axial isolator and prolongs tool life.

*High-Temperature (HT) variant designed for optimal isolation at 350°F (175°C). Prolonged exposure to elevated temperatures may shorten elastomer life. For temperatures below 275°F (135°C), use the standard tool & elastomer kits for optimal performance. The standard tool can easily be upgraded to the HT variant as needed simply by rebuilding the tool with the HT elastomer kit.

Upgrade an Existing Axial Isolator

Axial Isolator Fin Kit

Fins are available in all standard sizes. Not only does this eliminate the need to cut fins to size in the field, it also preserves the molded edge of the fin. This results in more consistent performance and lateral support while mitigating wash.

Customers can purchase a standard axial isolator or one that is designed to accommodate fins (Fin-Ready Option referenced in above table). Fins are purchased as a separate kit (featuring three molded fins, six fasteners, and a hexagon key for assembly), and can be installed by LORD upon initial purchase of the centralized tool.
