The following statement suggests that they will test oil in each of the upper 5 sandstones........Oil pay was encountered in the A4, A3, A2 and A1 sandstone zones and two shallower sandstone intervals above the A1 zone. All oil-bearing sands appear to be oil charged throughout, with no evidence of any oil water contacts within any given sand.
This is the first good quality oil pay of significant thickness encountered in the A3, A2, A1 and shallower sandstone zones by any well drilled to date, and highlights the potential of these sands as primary reservoir targets in adjacent, currently undrilled, fault compartments............
A4 started out with just 10 % wc, so that zone does seem to be very close to the water/oil interface.
But, the upper 5 may or may not..
