Gas and Oil Traps, page-13

Bomber, the image was just taken out of an online Geology information course and is merely ment to be a schematic mock up of how these things might look.

General concept that I was getting across is that it often depends where you drill the hole in the oil/gas trap as to what you can expect to intersect.

I doubt anything in Mauritania is as simple and straight forward as the image, and after having a look at the FOG website, I tend to agree with Oli that Banda will probably have more of a stratigraphic trap.

Hope this helps.
