What is Sonic Log Porosity Calculation Guide about?
This document discusses using sonic logs to determine porosity in geological formations. It presents the Wyllie time-average equation for calculating porosity from interval transit times measured on sonic logs. Typical interval transit time values are given for different rock types and fluids. Examples are provided of using a porosity chart or calculator to determine porosity from a given interval transit time, matrix slowness, and fluid slowness. It also discusses correcting porosity measurements in uncons
