Abstract

This paper presents the development of improved log-derived permeability rela- tionships through more accurate pulsed neutron evaluations of the Nipisi Gilwood "A" Sandstone. Existing pulsed neutron derivations have given an indication of flowing watercuts, poten- tial flow profiles and residual oil satura- tion. Improved interpretation techni- ques combine existing open-hole porosi- ty data with pulsed-neutron data to pro- vide better evaluation of cased-hole water saturation, log porosity and log- derived permeability.
