Reservoir Engineering

Well Test Design and Analysis


This course stresses the practical application of well test theory to design and interpretation of pressure transient tests. An integrated approach to well test interpretation is emphasized throughout the course. Class exercises involving hand calculations and simple spreadsheet applications will reinforce the concepts covered in class. Concepts will be illustrated by both synthetic data sets and real field examples. Participants will be able to apply the knowledge and skills in their job assignments upon course completion.



By the end of this course participants will learn how to:

  • Analyze drawdown and buildup tests in oil and gas wells.
  • Identify flow regimes using the log-log diagnostic plot.
  • Describe characteristic pressure behavior for common bounded reservoir geometries.
  • Identify well test data affected by various wellbore and near-wellbore phenomena.
  • Design a well test to meet desired objectives.
  • Estimate average drainage area pressure.
  • Analyze well tests in hydraulically fractured wells.
  • Analyze well tests in horizontal wells.
  • Analyze well tests in naturally fractured reservoirs.

Target Audience

Engineers and geoscientists who want to understand well testing principles and interpretation techniques to design, analyze, report, evaluate results or intelligently participate in the well testing process. Previous experience in production and/or reservoir engineering is recommended. Previous experience in well testing is helpful but is not required.
