Basic Log Analysis and Understanding
In the world of petrophysics there are very few black and white rules. Many different techniques can be used to calculate different results. The different calculations being used in today’s analysis can have a large impact on the outputs. What is the difference in water saturation calculations? How can we calculate TOC differently? How do I get porosity from the different tools? What can I do if I don’t have a full data suite? What happens with different vintages of logs or different logging companies? What is the critical data for a complete understanding of the reservoir to be characterized?
