Oil Tech Services has acquired and is committed to extending and enhancing the technology originally developed by General Electric in 1969 to insulate permafrost production zones in wells at Alaska North Slope. The original concepts and insulations systems have advanced and High Vacuum, High Performance insulated tubulars are manufactured for steam injection wells.
Our mission is to be a reliable source of Vacuum Insulated Tubing, progressively improving the technology, performance and reliability. Our manufacturing is in Houston Texas. We provide the high quality Vacuum Insulated Tubulars enabling injection of high quality steam into deep heavy oil bearing zones. Strings can be customized for size, thermal performance and thread connection system.
Thermal Tube 1, 1-H, and 2 (Inert Gas Backfilled)
For Intermediate Insulating Capacity at Temperatures Below 400°F.
Thermal Tube 2-H (Inert Gas Backfilled)
For Intermediate Insulating Capacity at High Temperatures up to 670°F. Thermal Tube 2-H is an inert gas backfilled tubular product. Mechanically it is the same as the higher performance 3-H (High Vacuum, Getter tubing)
Thermal Tube 3-H (High Vacuum, Getter™ maintained)
For Maximum Insulating Capacity at High Temperatures up to 670°F, and depths to 5000 feet.
