    Basic Log Analysis and Formation Evaluation - RILS

    Basic Log Analysis and Formation Evaluation - Remote delivery Series is a basic level course that is focused on open hole well logging and fundamentals of formation evaluation. The course is designed to be delivered remotely using either a 5 sessions that are 6-7 hours each or 10 sessions that are 4 hours each.  The course can be delivered as a public class or customized for private offerings.  The course is designed for any technical person that needs a general knowledge of open hole well logs and basic formation evaluation. The course uses several workshops to introduce participants to the well logging tools, evaluating lithology, determining porosity, determining fluid saturations and fluid types. The workshops are designed to be completed using Excel versus commercial software.  Participants will complete a pre and post course technical assessment, so that they know how they improved during the training. During the final session, participants will complete an open hole well log evaluation.
