Well Setting and Operation Geology


Why Choose this Training Course?



The main objective of this course is to provide a comprehensive understanding of how to monitor and use geological data acquired while drilling in order to characterize geological formations and reservoir characteristics.



Learning Objectives



Upon completion of the course, participants will be able to:

• understand a well-site geologist’s role, tasks and responsibilities,

• Grasp various techniques applied in well-site geology and during coring operations.

• Learn about the various aspects of operations geology and geological logging.

• Describing hydrocarbon shows under microscope.

• Correlate all offset wells using mud logs and E-Logs.

• using wire line logs for quick evaluation.

How will this Training Course be presented?



The course will not only presented by showing and interpreting the material in detail, but also the participants will work together using a real data to apply all the workflow and to project their previous knowledge and experience onto the course, they also encouraged to bring their own data so that real working examples can be reviewed and interpreted.



Who is this Training Course for?
