Video conference BP technical briefing on Blow Out Preventer (BOP) failure and general update on Gulf of Mexico oil spill (10 May 2010)
Video Source: http://bp.concerts.com/gom/bptechbriefing051010.htm
Key Points from Video:
- CEO describes current state of the efforts as of May 10, 2010
- top hat approaches failed because sea bed water temperature is 30 deg F, which upon contact with methan gas immediately formed hydrates (methane clathrates, icy “slush”) that plugged the “hat” and prevented oil flow/collection.
- description of top kill approach
- exploding of deepwater well in attempt to close it is unknow and is not considered as an option
- intersection of Deepwater Horizon well bore with relief wells is not easy, but doable.
