Abstract

Potential producibility and the proportion of water and oil produced can be predicted for hydrocarbon bearing reservoirs using an isolated pore model and nuclear magnetic resonance data. The model is based on the use of two bulk volume irreducible/free fluid index cut off times, one based on small pores and the other based on large pores with a throat size that will not permit movement of fluids therefrom.
