458 Mil is an estimate, but the Rig Update 37 days ago is interesting... could it be the Rig itself is drilling elsewhere and not in KINA? or is KINA being drilled again? Thank you for spotting that!
The Oil estimates where based upon the pre-drill seismic. They mean little once the prospect is actually drilled and found not to contain oil. They only exception to this would be if they drilled into sands that were not in communication with other oil bearing sands. But I believe during the CC call it was mentioned they would be drilling other prospects if there was additional drilling, which would suggest they are satisfied they know what was in those prospects.
