Modern Well Test Analysis

Modern Well Test Analysis is a 5-day well test analysis course personally conducted by Dr. Roland N. Horne. This highly regarded course has been attended by thousands of oil and gas, and geothermal professionals around the world for more than 20 years.

In this course, Dr. Roland Horne will teach you how to:

  • Interpret well tests to determine the properties of oil, gas and geothermal reservoirs.
  • Analyze transient well data to diagnose well condition.
  • Design well tests for maximum efficiency and success.
  • Use computer-aided interpretation tools.

Participants will learn the latest techniques to analyze complex wells or reservoirs. Modern topics that will be included are:

  • Horizontal wells
  • Fractured and stimulated wells
  • Multilayered reservoir analysis
  • Variable rate and continuously monitored well tests
  • Derivative plot interpretation
  • Nonlinear regression and computer-aided analysis
  • Multiple well tests
  • Gas well analysis using pseudopressure and normalized pseudopressure
  • Naturally fractured reservoirs

This course is hands-on, and consists of lecture presentations and doing exercises using laptops and software featuring all the latest well test analysis techniques. The course will use commonly applied commercial well test interpretation software, which will allow the participants to practice analyzing real and example well test data, using the same tools likely to be used every day in their companies.

Attendees should bring their own laptop to the training and are encouraged to bring their own well test data for discussion during the course – either in the class or individually with the instructor.

Participants will also receive a textbook on modern well test analysis written by Dr. Roland Horne and more than 30 examples of well test examples for further learning after the course is over
