CrazyJogger925, please consider the following facts.
Any contradictions should be based on facts -- provide links and/or citations as I have done, not the emotion shown in your post (moderators -- thanks for removing, but I am still providing this clarification as I may not have adequately documented my belief that 2% is the most recently independently developed estimation of chance of success).
To restate: the 2% comes from the 2008 RPS Energy Report, as quoted by EEGC in its September, 2009 final report to MRT on SEL 13/98 as posted on the EEGC website, page 73.
If you disagree with mine and others' interpretation of the 2%, please indicate why, as I suggested in my posting.
This same EEGC report, page 5, also quotes the RPS Energy Report -- and follow-on WHK Denizen Competent Persons Report -- in stating that there are 669 Billion barrels of 'undiscovered prospective oil and gas resource.'
I believe these are the most recent RPS Energy and WHK Denizen reports, since the March 5, 2010 EEGC Press Release refers to 668 Billon barrels (note: I can't explain the 1B discrepancy, let's assume rounding error).
Net: I think 2% is the most updated percentage for Chance of Success, but if you are aware of more recent work done, please provide the link.
