Principles and Applications of Well Logging

Reservoir Descriptions and Dynamics


The objective of this 3-day course is to provide log practitioners with a solid understanding of the principles and applications of open hole well logging data.
Open hole well logging is fundamental to the quantification of hydrocarbon resources during the exploration and appraisal phases and to reservoir delineation and surveillance during the development and production phases. Topics include:

  • Basic geology and petrophysics
  • Planning and execution of logging operations
  • Log quality control and basic environmental corrections
  • Quick scan methods for determining  zones of interest
  • Determining Archie parameters and using to determine saturations
  • Non-standard log evaluation methods for shaly sands, carbonates, etc.

Learning Objectives

At the conclusion of the course, participants will be able to:

  • Scan a well log for quality control
  • Define zones of interest on a log
  • Implement basic log quality control and environmental corrections
  • Determine Archie parameters and using to determine saturations
  • Design and supervise a  basic logging operation
  • Decide where and when advanced  logging technologies may be required

Who Should Attend

The target audience includes earth geoscientists and engineers involved in the acquisition, interpretation, or use of well logs. This is a mid-level course that provides a broad overview of open hole logging methods and practices as well as basic open hole log interpretation.

Special Requirements

  • Portable computer/laptop
  • Participants should have a basic understanding of petroleum engineering concepts
  • Attendees need to bring relevant logs and log evaluation problems to use as in-class exercises
