HPHT “ Steam Well” Connection Compounds

Utilizing Engineered, Cross-Link Polymers as Sealing and Locking

Compounds for HPHT Connections

Presentation Overview

The goal of today’s presentation is to highlight the benefits of utilizing crosslink polymers in Premium and API threaded connections in High-Pressure / High-Temperature environments.

What are Cross Linking Polymers?

• Combination of monomers, curing triggers and fillers.• New “Advanced Monomers” deliver improved

performance up to 600 Degrees Fahrenheit.• Advance locking and sealing compounds are now

engineered with various curing triggers and fillers.• Curing can now be controlled AND triggered three

ways:– Anaerobically (Absence of Oxygen)– Temperature (Set the curing Temperature Trigger Range)– Active Metal (Chrome, Ferrous, Copper)– OR a combination of any of the three

“A one-size-fits-all pipe dope or first generation cross-link polymer is no

longer adequate to address the challenges and varying complexities of

HPHT applications.”

First Generation Polymer Limitations

• Single cure mechanisms (Anaerobic)

• Do not include advanced high temperature monomers and polymers rated to 600 Deg. F.

• Limited strength and failures under extreme high pressure (Failure at 11,000 PSI+ external gas)

• Lack of control in thread make up.

Next Generation Polymer Advantages

• Polymers that are “Designed” and ”Engineered” for specific HPHT applications.– Temperatures – 400-600 degrees Farhenheit– Successfully tested at pressures up to 15,000 PSI– Locking mechanisms to address over torque and

backlash– Addresses thermal cycling failures– Tension and compression in horizontal applications– Compound “Bake Out” and “Out Gasing”– Connection damage during makeup– Custom engineered shear strengths

High Pressure External Test Data

• Recent external gas pressure test (July 2014) was successful to 15,062 PSI and temperatures as high as 260 degrees F.

• First generation compounds failed at 11,500 PSI.

• No external seal in premium metal to metal connection.

• 200 degree F triggering compound applied.

• Test performed by Stress Engineering of Houston, Texas

Conclusion

• Advanced, next-generation polymers and monomers enhance the performance of premium connections while providing greater flexibility and control.

• These advanced polymers and monomers also enhance the performance of standard API 8rd and Buttress threaded connections.

• Custom engineered solutions can be designed to meet a complex range of variables in the most challenging HIGH-PRESSURE / HIGH-TERMPERATURE environments.
