Nuclear magnetic resonance determination of the non-pore water content of zeolitic tuffs and its application to correction of epithermal-neutron-log-derived water content

PDF Version Also Available for Download.

Description

The use of free water obtained from correction of log-derived total water for the non-pore water measured on desiccated samples appears to result in more plausible values for calculated saturation properties in zeolitized rocks. There is evidence that grain density can best be measured using helium pyncnometry of samples kept at a controlled humidity. The best procedure would be to measure both grain density and bound water in the same samples at the same humidity. Under those conditions, desiccation would not be necessary, and the values of grain density and water content used in Eq. (1) would be completely compatible. ... continued below
