Wireline Logs

Abstract

Petrophysical measurements and rock-fabric descriptions provide a basis for quantifying geological descriptions with petrophysical properties but are point data and have no spatial information. These measurements and descriptions are expanded in one dimension by detailed sampling of core material. However, cores are normally available from only a few wells, whereas wireline logs are available from most wells. Therefore, rock fabric data and facies descriptions must be calibrated to wireline logs to expand the coverage of one-dimensional core data.
