    1. BOEMRE UPDATE AADE Luncheon Meeting 3 March 2011 John Peters

    2. After the Incident - DOI/BOE Gave a Clear and Consistent Message Improvement needed in three areas before drilling will be allowed: Prevention of another blowout Demonstrate increased intervention capability Demonstrate increased oil spill response capability Industry heard the message loud and clear 2

    3. Energy Industry Response Initially Created 2 Joint Industry Task Forces Prevention - May Operating Procedures Task Force Equipment Task Force 3

    4. JITF (Operating Procedures & Equipment) White Paper Recommendation Cementing – API RP65 Part 2 Develop DW well design standard (now API RP 96) Lock casing hanger in HPWH Close BOP’s to circ out Lighter Fluids to prevent gas in riser Monitor volumes in and out of wellbore Position shearable components across shear rams Recommend 2+ independent barriers for each flow path Safety Case & WCID (now API Bul 97) Robust MOC ROV stabs - API Spec 17H 4

    5. Increased Safety Measures 30 Day Report (aka Buffalo Report) Certification of Subsea BOP Stack Blind Shear redundancy, ROV access, secondary controls, etc. New Testing – Auto Shear, Deadman, etc. New Deepwater Well Control Circulate out lighter fluids with BOP’s closed Lock Hanger, Negative testing, etc. Wild-Well Intervention - Containment Increased Enforcement of Existing Safety Regulations and Procedures Safety Case and WCID ETC, Etc, etc 5

    6. NTL 2010-N05 One time Corporate Officer Compliance Certification (Executive Level) One time BOP data set … etc Ongoing 3rd Party BOP Certifications by well Ongoing PE Certification Letter by well ETC, Etc, etc … 6

    7. NTL 2010-N06 Ongoing Worst Case Discharge submission by well ETC, Etc, etc … 7

    8. Energy Industry Response Created 2 more Joint Industry Task Forces Intervention - July Subsea Intervention and Containment Task Force Spill Response - July Oil Spill Response Task Force 8

    9. Interim Final Rule Drilling Safety Ongoing API RP 65 Part 2 Compliance Questionnaire Ongoing Should = Must in API Standards referenced in CFR(?) There were already 97 Standards referenced in the CFR Of these, 37 apply to D&C Operators and/or Contractors: ANSI/ASME - 4 API - 31 AWS - 1 NACE – 1 ETC, Etc, etc … 9

    10. Final Rule Work Place Safety One year to deploy Ongoing Safety and Environmental Management System (SEMS) requirements Modeled after API RP 75 Holds Operator accountable for all aspects of Safety and the Environment, inclusive of actions of their Contractors ETC, Etc, etc … 10

    11. Ongoing Compliance Statement by well (Drilling Manager or Other) Ongoing Containment Plan by well ETC, Etc, etc … NTL 2010-N10 11

    12. NTL-10 Containment Level 1 WCD Casing Spreadsheet Level 2 WCD Casing Template (if exceeds Level 1) Need Oil Gradient discussion justification Need No Broaching to Mudline discussion justification Need Detailed Casing Design analysis – WellCat for Thermal modeling, ETC, Etc, etc. BURST – Due to Capping Stack shut-in on Oil Gradient COLLAPSE – Deep liners, due to flowing internal Oil Gradient against Seawater at Mudline 12

    13. Application for Permit to Drill (APD) Roadmap 13

    14. Industry API RP 96 – Deepwater Design Considerations Shall circulate out lighter fluids w/ BOP's closed. Shall lock hanger in the HPWH as next reasonable step. Shall have a Barrier Plan. Shall have a Negative Test and Fluid Displacement Plan. Shall use a MOC process. Shall have a Stop Work Authority program. ETC, Etc, etc … Target Release ~ April / May 2011 14

    15. Industry API Bulletin 97 – WCID Section 1 – Well Construction Interface Plan to simplify Section 2 – Safety and Environmental Interface Plan to align with SEMS only and remove reference to Safety Case Target Release ~ April / May 2011 15

    16. Thank you All Ahead Full 16
