Objectives
How efficient would a vertical well drilled updip be in draining the reservoir?
How much oil would be left behind because of progrades and lateral pinchouts of reefs?
Would a horizontal well be required and should it be along strike or downdip to intersect the maximum number of progrades?

Pair 1 (I1-P1)
Pair 2 (I2-P2)
Pair 3 (I3-P3)
But Why Pair 1?!?

ConclusionAnswered all the questions asked by geologists
Developed a method of building connected volumes to identify drilling targets
Optimized wells for better recovery of this analog model
Further study can be done through completion optimization, drilling economics
