This study addresses the porosity analysis, using log measurements, of Cotton Valley sands in 19 wells of the Terryville field operated by Union Texas Petroleum Corp. The objectives of the study were to recognize logging tool miscalibration and make correction, determine petrophysical parameters for the Cotton Valley sands, reinterpret the field using new petrophysical parameters, and determine productive limits for log derived porosity and water saturation. Digitized log data was crossplotted to determine the correspondence between log and mineral responses and verify good calibration of each logging instrument. Predominant minerals were identified by the crossplots core analysis and mud log record. A lithologic model was then constructed on an in-house computer and used to reinterpret each of the 19 wells.
