3. Conference call Participants:  Apology  Repsol, Occidental, ExxonMobil, Chevron, ConocoPhillips, BP, Total, Aramco  SLB, BHI, 3M, CurisTec  Company changes Efforts:  Clarified intent of doc use while staying aligned with existing docs  Discussed outline “line-by-line”  Cleaned up items leaning towards regulatory  Temp removed topics to be covered in TR1 re-write  Support of E3 re-write will help populate  Generated a revised document outline 3Joe Shine - WG WA - 2016 E&P Summer Std Mtg – SC10 - CSOEM

4. Document outline after call Introduction  Objectives and scope Applications and operating variables  Formation types, lengths/positions, temp & press, well trajectory, well location, radioactive sources Property/material consideration for barriers  Cementicious, non-cementicious, natural/earth, mechanical, environment Installation  Well geometry, software placement simulations, placement methods best practices Evaluation and verification criteria  Annular – wireline logs and pressure match/post job evaluations  In pipe – physical/mechanical tests, hydraulic tests (positive and negative) Annex  Lab testing, other/TBD 4Joe Shine - WG WA - 2016 E&P Summer Std Mtg – SC10 - CSOEM

5. Feedback Chevron:  Add operational barriers (from RP 96) verbiage  Replace “negative” testing with “in-flow” testing 5Joe Shine - WG WA - 2016 E&P Summer Std Mtg – SC10 - CSOEM

8. Forward plan 8Joe Shine - WG WA - 2016 E&P Summer Std Mtg – SC10 - CSOEM August conference call  Collaborate on building out each sub-sections for 4, 5, 6, and 7  Discuss for each what to cover including any specifics/points  Capture content/notes and send out for review/edits/feedback October conference call  Discuss E-3 re-write incorporation to streamline (if available)  Based upon Aug content (and E-3), assign section leads Section leads - 4, 5, 6, 7  Start drafting sub-sections 4, 5, 6, 7 based on WG notes (and E-3)  Report monthly updates to WG chair  Bi-monthly conference calls with WG on section progress/feedback  Sections submitted to WG for peer review/feedback/edits before calls

9. Finally 9Joe Shine - WG WA - 2016 E&P Summer Std Mtg – SC10 - CSOEM Winter conference 2017  Check alignment with TR1 re-write  Report update to SC 10

10. WG Charge “Identify literature and gaps associated with well plugging and abandonment for both offshore and onshore environments. Present findings to serve as foundation to develop a RP” 10Joe Shine - WG WA - 2016 E&P Winter Std Mtg – SC10 - CSOEM
