According to documents filed by British Petroleum with the US Minerals Management Service, there are two wells in the area of the spill. The first well, Well "A", was drilled early this year, ran into troubles, and was abandoned. Then Well B was drilled, which resulted in the explosion which destroyed the Deepwater Horizon. (
There is a typo on page 10 of the MMS PDF regarding the Y coordinate for well B. The Y coordinate is correctly printed on page 3 and page 11. You will see that the dyslexic person who typed out the report switched a '1' and a '4' on page 10. Please be aware of this because otherwise it will lead to a lot of confusion!!)
I will allow a reader to explain further about which well we are currently being shown...
I put these simple sheets together to show people who don't have time to through my very long blog post the clear side-by-side comparisons of Well A's onscreen ROV coordinates with it's planned location in BP's Initial Exploration Plan for MC252. Under that are three different video captures of Well B spewing oil, and the Plan's coordinates for it. This should be easy enough for even people who haven't been following the story to understand.
