This structure is certainly a good starting point. But will need something more

• Cased hole test of Unit-1B limestones.
• Perforated casing over multiple intervals @ 6spf.
• Total shot length of ~76m over a gross interval of 443m (17%).
• Upper section dominated by porosity/matrix while lower portion dominated by fractures.
• Multi flow test conducted on a variety of chokes over 24 hours with a 48 hour shut in. Additional flow for further sampling conducted
after shut in.
• Average stabilised flow rate of 1235bopd achieved through a 36/64” choke over 12 hrs.
• Lab analysis of samples indicate a lighter, higher mobility oil of ~19°API.
• Reservoir pressure built up quickly indicating good permeability with no depletion observed.
• Interpretation indicates a minimum 16 mmbbls STOIIP observed during the DST.
• Established column of 344mTVD tested in the well
• Cement indicated over basal perforation zone. Hence some uncertainty of how uniform was the contribution to flow.

Add a bit of stimulants, who knows what could be achieved.
