Title: Techniques for mapping the types, volumes, and distribution of clays in petroleum reservoirs and for determining their effects on oil production

Abstract

This report presents the results of correlation of log signatures with information on distribution of the types and volumes of clays in sandstone pore spaces determined from detailed CT-scan, XRD, SEM, and thin section analyses of core samples from three sandstone reservoirs. The log signatures are then analyzed to determine if suitable mathematical/statistical parameter(s) could be calculated from the logs to determine their effects on permeability and oil production. The variability measures obtained from power spectral analysis of permeability and wireline log data in clayey formations have been correlated with oil production from two oil fields. Compared with the conventional measures of permeability variations like the Dykstra-Parsons coefficients, the new measure appears to correlate better with oil production.
