... Abstract The standard method of computing porosity for the two-detector Compensated Neutron Log (CNL) is to use the ratio of near to far detector count rates. This procedure has the advantage that, to first order, environmental effects tend to cancel, leaving only residual effects...

... of the excavation effect are presented. In addition, the potential use of various combinations of neutron detector count rates as gas indicators is examined. Calculations suggest that these indicators may complement the traditional phi density phi newton gas signal in useful ways especially when deep phi newton gas...
