Yes!!
In my opinion, they have a damn good picture of blocks 1, 2, 3 and 4 with all the 3D, wells drilled to date and info on Akpo and OBO, which are real close by and in the same zones. They might not know exactly how much without more wells being drilled but just as SNP's website says, they know.
Also remember, these guys drilled the very tops of these traps, insted of the anticlines and had it planed to cement surface pipe in, after they drilled some gas zones on Kina. Neither up to par in my part of the world.
