Technical Article: Compliance with API Specification 17D for Subsea Tree Design in 15,000 PSI Environments – Aligning with BSEE Regulatory Requirements

Introduction In deepwater oil and gas developments, particularly in high-pressure reservoirs of the Gulf of Mexico and similar regions, subsea production systems must withstand extreme operating conditions while ensuring safety, reliability, and environmental protection. Subsea trees—assemblies of valves, chokes, connectors, and associated equipment that control flow from subsea wells—play a critical role in these systems. […]

Elastomer Selection for HPHT Seals & Subsea Valve Failure Analysis: Diagrams, Causes & Mitigation

By Oko ImmanuelPetroleum/Subsea Engineer | Founder, Offshore Pipeline Insight | Texas A&M AlumnusMarch 12, 2026 High-pressure high-temperature (HPHT) environments pressures >10,000 psi and temperatures >150–200°C are among the most demanding conditions subsea equipment faces. Elastomer seals in valves, connectors, packers, and downhole tools are often the weakest link. Choosing the wrong elastomer leads to extrusion, […]
