PfEFFER 3 (proposed)
Hydrocarbon storage and hydrocarbon and water flow for each
depth increment
Permeability classification, fracture detection, pay and shows,
genetic stratigraphic classification, and general search of well
logs for prospective pay or other petrophysically based criteria
("Knowbot")
Volumetric calculations and material balance including:
- residual oil in place,
- residual oil saturation, and
- residual mobile oil.

Volumetrics and Material Balance
- Quick look comparison of recovery to OOIP
- Check accuracy of reservoir parameters
- Material balance provide independent assessment of effective
reservoir volume
- Preliminary steps to running reservoir simulation
