SEMINAR
OUTLINE: PRACTICAL QUANTITATIVE LOG ANALYSIS
 
SUMMARY:
This quantitative course covers all topics needed to calculate
shale volume, porosity, water saturation, permeability,
volumetric reserves, and flow capacity from modern open hole
well logs. Integration and calibration to cores, tests, and
production data are stressed. This is a practical, no-nonsense
course covering both visual and numerical analysis methods, with
numerous real-world exercises. Quick-look, visual, calculator,
and spreadsheet methods are all covered; includes free
downloadable spreadsheet software.
