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
Shock Count Comparison
| Magnitude | Without LORD Axial Isolator | With LORD Axial Isolator |
|---|---|---|
| 30-40g | 1495 | 2 |
| 40-50g | 70 | 0 |
Axial Isolator Variants
*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.
Combined Axial & Lateral Protection for MWD Tools
As lateral shock and vibration become an increasing concern, we have addressed the problem by incorporating lateral stabilization into the axial isolator. This is easily accomplished by swapping out the standard sealing sub with part number J-28460-72, giving the user the ability to customize the fin size to maximize lateral shock and vibration mitigation. Available bonded fin sizes are shown in the table below.
