We present the procedures used to develop an accurate wireline-log database for the Fullerton Clear Fork field reservoir. We first review the borehole logging history of the field then discuss the assembly and quality checking of the log data and normalization of neutron-porosity logs, and calibration to core porosity. The procedures documented here deviate somewhat from the norm in that the assembly of the database and quality control of data occurred concurrent with data interpretation. Because of the complex nature of the field data, traditional log-normalization methods were not adequate. A method of normalization is described that is a modification of traditional methods, which overcomes the unique problems of the Fullerton Clear Fork reservoir.
