Computer Coordinated Core & Log Interpretation

Analysis of information from the three basic tools for formation evaluation (cores, logs and tests) requires the common steps of quantifying the physical measurements, correlating or zoning the data and interpretation. The improved reliability of modern measuring equipment and instrumentation has created a growing awareness of the inherent limitations of each tool and of the need for close coordination of the data prior to the final interpretive step. The Pure Oil Company COMLOG well log interpretive computer program, under license to Core Lab., has been modified to accept core analysis parameters. It provides a coordinated interpretation of the information captured by logs and core analysis, as complementary information sources. The flexibility of the expanded program permits application of local experience factors, serving as a manipulative interpretive tool for the formation analyst both in research and operations. Examples of such coordinated interpretation demonstrate the ability to perform detailed analysis from log and core parameters, producing more definitive results than are obtainable from either information source alone.
