*Stock Tank Original Oil In Place (at reservoir conditions)

This well was in a Heavy Oil Reservoir which had never been completely evaluated, developed or significantly produced, due to low oil prices.  With the return of stronger commodity prices, The field was being considered for Enhanced Oil Recovery.  The above petrophysical analysis was from one of the few wells in the field with a complete wireline suite (dual induction, gamma ray, SP, compensated density, compensated neutron, and caliper).  Routine core analysis (KPS) returned reservoir rock air permeabilities of several darcy,  with the lower zone apparently interbedded shales and sands.  Formation water is very fresh (approximately 6,000 ppm NaCl equivalent) and the crude is very heavy (less than 13° API).  Detailed shaly-sand analyses, like the one above provided information which could be transported to those wells in the field, without complete wireline suites, so that initial in-place reserves could be estimated for use by the Qualified Reserves, Reservoir and EOR Engineers in their assessment of recoverable reserves and development of an EOR production engineering design.
