Reservoir size
Reservoir sizeMaybe I am totally wrong, but here is a rough calculation.
From the maps, the field looks like a 4km x 1km anticline with several bumps.
So we get 4000m x 1000m x 13,7m (45 ft).
That is 54,800,000 m3.
As this is not a full sized box, I will assume 1/3 of the volume as the pool size.
That is 18,266,666 m3 oil bearing sands.
Assume 0.33 porosity, 0.8 oils saturation and 0.4 recovery factor:
1,928,960 m3 oil recoverable or 12,133,158 barrels.
No FVF applied so far and it is only rough, but looks like something around 10 million barrels recoverable to me.
Opinions from the real experts?
