Dynomax Shock subs

Shock subs Dynomax

Description

Whether performing through normal, deviated or deep wells, your drill string assembly must withstand the extreme conditions including torsional vibration, axial oscillations/loads and drill string harmonics.

Dynomax Shock Subs are designed for a wide range of drilling environments and extreme conditions. Shock Subs improve the life and durability of your drill string assembly, improving online efficiency and operating costs.

Our Shock Tools are designed for easy assembly and easy service. They can be combined into drill strings with other downhole tools quickly, and can be detached, reducing service time and costs. 

Every Dynomax Shock Tool undergoes stringent performance tests, and we ensure that our testing models and QA/QC programs meet or exceed any in the oilfield industry.

Features: 

  • Significant vibration absorption.
  • Reduction of drill string harmonics.
  • Smoother and faster drilling downhole.
  • Longer bit life.
  • Protect instruments and body connections.
  • Increased Tool bearing life.

Dynomax can offer shock subs for higher temperature applications with specially designed seals for temperatures above 350°F (175°C).
