Well Test Design and Analysis

• This course stresses practical application of well test theory to design and interpret 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 illustrated by both synthetic data sets and real field examples.
• Participants will be able to apply the knowledge and skills they gain in this course to their job assignments upon course completion.

YOU WILL LEARN:

• 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, horizontal wells, and naturally fractured reservoirs
