The STM-15 E subsea wellhead system is used for wells being completed with a subsea tree tied back to a fixed bottom-supported platform, and for drilling exploratory wells. The system is ideal for all 15,000-psi drilling and completion operations in moderate water depths.
The high-pressure housing is machined from F-22, 85,000-psi-yield forged material and is available for H2S service. The STM-15 E system incorporates the field-proven parallel bore metal (PBM) metal-to-metal seal.
