HOUSTON– Vallourec has developed a new drill pipe based gas tight connection with metal-to-metal rotary seal technology. This high-pressure connection allows the same drillstring to be used for both drilling and completion operations.
This new double-shoulder gas tight connection provides the high-pressure capability of premium casing or tubing connections coupled with the robustness and increased torsional strength associated with a double-shoulder rotary connection. The company says it is qualified to 30,000 psi (2,068 bar) internal pressure and 25,000 psi (1,724 bar) external pressure.
