Resistivity-Velocity Log Evaluation Of The Morrow Sand In We
Empirical curves which related weighted core porosity and formation velocity or transit time have been developed for the relatively shale free Morrow sand in western Oklahoma. The effect of fluid and residual gas in the invaded zone has been investigated and is considered in the empirical curves. The comparison of formation resistivity and transit time using specially designed graph paper in many instances provides a rapid method of formation evaluation. Some examples showing the application, advantages and limitations of the procedure are presented.
