Abstract
An improvement in the method of determining oil saturation in a subterranean formation, penetrated by a well-bore, is disclosed. In the method of determining oil concentration by measuring thermal neutron decay with a low salinity aqueous liquid in said well-bore and said formation, and measuring thermal neutron decay with a high salinity aqueous liquid in said well-bore and said formation, the improvement comprises adding to said low salinity liquid in the well-bore, only, a material which adjusts the thermal neutron capture cross section of the well-bore so that it is approximately the same as the thermal neutron capture cross section of the well-bore when it contains the high salinity liquid.
