Jim, yes the depositional geology is different from Macondo, in that the layers of sediment have been laid down very slowly over millions of year and there is no high pressure gas trapped. The Macondo environment had a deposition that was laid down very quickly in geological terms, which trapped a lot of gas, so not allowing time for it to escape, thus creating extremely high temperatures and pressures which made drilling a lot more risky.
It's clear the carbonate rock BPC has is vuggy and porous and can hold a lot of oil which will flow. The main risks are charge and seal. Migration pathways from the source and faults that extend into the folds allow the charge, and the lack of oil seeps over the structures compared to elsewhere indicate the seal is in tact, so the main doubt is is there enough charge to fill the structures. Surrounding oil wells with live oil and signs of migrated oil due to failed seals and invalid traps would suggest plenty of oil has been generated.
