Course Description

Although some experience with reading logs is an advantage, this course is ideal for anyone who has no prior knowledge or experience, especially newcomers to the oil industry.

In one week you will gain all the confidence you need to understand and interpret all the basic open-hole logs.

Course Objectives

  • Understanding and  recognize all the basic logs
  • Know what they are measuring 
  • Learning how to read them, recognize all the common rock types
  • Identify hydrocarbon zones, calculate porosity and water saturations
  • Have confidence in your choice of interpretation parameters.

Who Should Attend?

  • Geologists
  • Geophysicists
  • Petroleum Engineers
  • Petrophysicists
  • Technicians/ Managers, if they are exposed to (or use) open-hole logs in their daily work.
