2. HPHT “ Steam Well” Connection
Compounds
Utilizing Engineered, Cross-Link
Polymers as Sealing and Locking
Compounds for HPHT Connections

3. 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.

4. 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

5. “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.”

6. 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.

7. 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

8. 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

11. External Pressures Exceed 15,000 PSI

12. 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.
