ABSTRACT

Integrating reservoir parameters derived from log and core data allows previously bypassed thin and productive zones to be identified. Recent advancements in enhanced data acquisition methods and well log interpretation techniques have reduced problems encountered with conventional thin-bed well logging and data analyses. Improved data acquisition methods record filter-free data at higher sample rates. Advanced log interpretation techniques utilize enhanced porosity, shaliness, and resistivity measurements to compute more realistic hydrocarbon saturation in thin beds. An advanced analysis program integrates reservoir parameters derived from core and well log data to provide an optimum reservoir description package for lithology, porosity, permeability, and probable production. These reservoir parameters are presented on a single, expanded-scale plot. Examples and computed key parameters using this technique are compared with the conventional log interpretation techniques.
