Strategy and Forward Plan
• Run a Safe Operation
• Long Term – Relief Wells
• Short Term – Containment
− Option to Shut-in Well; Test Integrity
• Leverage Industry and Government Expertise
• Multiple Parallel Options
• No Stone Unturned to Minimize Pollution

Containment: Mid July OnwardsCapacity 60– 80 mbd
![Page 9: Deepwater Horizon Source Control - Energy](https://reader031.vdocuments.site/reader031/viewer/2022013018/61d111120a30b70f577db607/html5/thumbnails/9.jpg)
Advantages of Further Enhancements
• Reduce Hurricane Impact
− Demobe/Mobe 4 days vs. 10 days
• Increase System Capacity & Redundancy
• Opportunity to Shut-in Well
• Aid Well Kill & Cementing

LMRP Cap
• Collecting from Enterprise
• Sits over the LMRP Flange
• Must be replaced to move to Long Term Containment
![Page 11: Deepwater Horizon Source Control - Energy](https://reader031.vdocuments.site/reader031/viewer/2022013018/61d111120a30b70f577db607/html5/thumbnails/11.jpg)
Execution Process
• Helix Producer full rate and stable
• Q4000 full rate and stable
• Remove LMRP Cap containment
• Install sealing cap assembly
• Well integrity test
• If shut- in unsuccessful
– Implement Mid July Containment
• Kill well via relief well

Sealing Cap
• Sealing Connection
• Necessary for Long Term Containment
• Replaces LMRP Cap
• Shut-in Option
