Confirmation of reservoir geo-model Material Balance Calculations

Critical question: Given the OOIP (original oil in place in the reservoir), the known PVT properties and aquifer description, can the reservoir produce the historic fluid volumes by undergoing the recorded pressure depletion?

Fluid column measurements at Waugh #1 and #3, as of May 2002, indicate a reservoir pressure of 1,750 psi.

The simulator predicts the average reservoir pressure to be 1,800 psi as of Jan 2003.
