Downhole

Helping Downhole Equipment Perform Reliably

Producers are continually pushing the limits as they design tooling in search of oil and gas at depths once thought inaccessible, and in areas where unconventional conditions and geology dictate unconventional recovery methods.  Whether on land or offshore, these more difficult sources for hydrocarbons challenge downhole service companies and component suppliers with adverse conditions such as:

  • Increasing high pressure / high temperatures (HPHT)
  • Low temperatures
  • Rapid gas decompression (RGD)
  • Explosive decompression (ED)
  • Aggressive chemicals such as ammonia, carbon dioxide, hydrogen sulphide (sour gas), methane, and steam

The combination of HPHT, RGD, ED and harsh chemicals can lead to seal failure which is responsible for costly safety and environmental issues, as well as lost production and shut-downs on your rig.

Importance of Polymer Seals and Sealing Elements in Downhole Tools

Some of the most critical components in downhole tooling are the sealing elements.  Extreme downhole operating environments require high performance seals that have been custom engineered and tested to ensure their reliability.  Our design engineers and materials specialists are capable of providing proven seals, bearings, and connectors for your toughest downhole challenges.  

Advanced Polymeric Materials for Downhole Applications

CDI has one of the most comprehensive portfolios of ISO / NORSOK qualified materials for chemical resistant PTFE plastics and elastomers, engineered to withstand rapid gas decompression (RGD) and explosive decompression (ED).  Our extensive expertise in custom compounding allows us to make products that serve in the most extreme downhole environments.

We provide in-house material development, custom compounding, and testing for a broad range of polymeric materials, including:

CDI also performs on-site testing of FEA and mold flow analysis in order to address problems before costly tooling is constructed, as well as simulation capabilities such as plastic flow, product design, and finite element analysis.

Engineered Solutions for Downhole Applications

We offer a wide variety of reliable, HPHT-stable, RGB and corrosion-resistant seals and components for use in your downhole tooling. From concept, to prototype, through production, our application engineers are available to solve your most demanding downhole sealing requirements, where and when you need us. Following is a partial list of applications in which CDI products can be found:

  • Drilling jars and hammers
  • Reamers and hole openers
  • Drilling motors and bits
  • Tubing hangers
  • Casing hangers
  • Chemical injection systems
  • Sub-surface valves
  • Packers
  • Pumps
  • Artificial lift systems (ALS)
  • Liner hanger systems
