I think the 3D will upgrade Ruvuma to over 10 TCF, possibly as much as 12 TCF.
This theory is based on the fact that the 2D Seismic (as Mike Rego says in his videos) had very wide lines, wasn't the greatest quality (compared to 3D) and was poorly understood, hence the issues found when drilling our wells, what was encountered was not exactly what was expected and the depths were not as expected, well data had to be continually added to the basin model to try and decipher what was seen on the 2D vs what was found in the well, this shows just how difficult the 2D was to interpret. (I was one of those shouting for 3D survey before Ntorya 2 was drilled, and right up to when we finally got it agreed with ARA).
The 3D Seismic however is very close lines of very high quality and shows the 3D shape of targets instead of just a line or two through a 2D section of it, maybe not even hitting it in both directions either. This means much more accurate volume calculations can be done as part of the Supercomputer processing of the data.
Also, the 3D is bound to show up more targets that it was not possible to determine as targets on the 2D, as the target could be mostly between the 2D lines, or just not clear enough.
The 3D could also show up more targets in the Jurassic which could potentially increase the resources significantly if we drill the Jurassic and find Gas there, or even Oil. This would be on top of the 10+ TCF I am thinking we will see.
