Demonstrates the techniques of conventional mud logging during the preparation of a formation log and accompanying event reports. Presents the rate-of-penetration curve, lithology plot, total gas curve, gas composition curves and descriptive track. Also discusses the use of mud logging in overpressure recognition, hydrocarbon evaluation and non-hydrocarbon gas detection. Summarizes computer-based data acquisition and measurement-while-drilling techniques.
