Course Description

This course provides a comprehensive understanding of how to monitor and use geological data acquired while drilling in order to characterize geological formations and reservoirs. The focus is on being able to understand the job functions that are typically performed at the wellsite, and what use is made of the large amounts of data collected. The course will also provide an overview of essential drilling operations that have a direct bearing on these discliplines.

Course Objectives

  • Understanding well-site geologist’s role, tasks and responsibilities
  • Grasping various techniques applied in well-site geology and during coring operations
  • Learning about the various aspects of operations geology and geological logging
  • Evaluating data before the start of drilling
  • Advising on drilling hazards

Who Should Attend?

  • Geologists
  • Geoscientists using well geological reports
  • Technicians involved with geological wellsite control and/or supervision.
