API SC 6 HPHT PR 3 Validation Why

API SC 6/ HPHT – PR 3 Validation Why Needed? • HPHT & Critical Applications – Defined by CFR for Surface Equipment as: Ø Ø • SITP at Wellhead of >15 M Flowing Temperature at Wellhead ≥ 350ºF Code of Federal Regulations: (30 CFR 250. 807) – Application to Drill / Modify (APD/APM) or Deepwater Operations Plan (DWOP) must include: Ø Ø A discussion of “related equipment’s” Design validation and functional test procedures A discussion of why the procedures ensure that the “related equipment” is fit-for –service in the HPHT environment – Related equipmentØ Wellheads, tubing heads, tubulars, packers, connections, seals, production trees, chokes, well control equipment and other equipment Design Materials Validation HPHT Approach QC 1

“HPHT / Enhanced PR 3 Validation” SC 6 Proven HPHT Experience Base? • • Starting Today’s Process with a Level of Confidence in our Legacy! – ≈ 30 years of Surface Equipment HPHT Applications – 1972 - API 6 A 9 th edition expanded to include 20000 PSI equipment – 1983 - API 6 AB Specification released for 30000 PSI Flanged Wellhead equipment – 1991 - API (Bulletin 6 AF 1) 1 st edition Temperature Derating Flanges under Combined Loads (Including 20000 PSI flanges) What Other Sub Committees Are Doing: – SC 17 (Subsea Wellhead and Christmas Tree equipment)- Validation testing varies, but should include results of FMECA to plan a “Reliability” Based validation test. – SC 19 (Packers and Bridge Plugs)- Requires FMEA or similar to plan validation testing and requires more stringent validation testing regardless – SC 19 (14 A SCSSV equipment)- Requires FMEA or similar to plan validation testing and requires more stringent validation testing regardless 2
