The Micro log as a Porosity Datum for the Neutron Log in the Swan Hills Field, Alberta

CIM Bulletin, 1960


Porosity neutron deflection scales can be derived more easily by cumulative correlation than by the conventional method of plotting corresponding points on a graph. The micro-log can be used as a porosity datum for the neutron log by transforming the permeability cut-off it shows to a porosity cut-off by a permeability-porosity function obtained from core analysis. Porosity footage values calculated in this manner from the neutron log are within 20 per cent of core analysis values.
