Medium to low porosity and rather tight Cherokee, Red Fork and Morrow sands, located in Oklahoma, contain significant hydrocarbon resources. To evaluate the commercial importance of wells drilled in Custer County, Oklahoma, an innovative digital shaly sand analysis approach (CLASS - Epilog) has been applied, which provides information on total and effective reservoir porosity, total and effective fluid distribution based on the Waxman-Smits equation, shaliness, clay typing, and reservoir productivity. Several field case examples are presented and discussed based on (1) open hole logging suite, consisting of induction, compensated density/neutron and Spectralog, (2) CLASS analysis, (3) well completion and stimulation data, and (4) the resulting production test results.
