Well Testing and Pressure Transient Analysis

Introduction

Accurate well testing and pressure transient analysis (PTA) are essential for understanding reservoir behavior, optimizing production, and making sound field development decisions. Whether evaluating a newly drilled well, monitoring production performance, or diagnosing reservoir challenges, well testing provides the critical data needed to improve recovery while reducing operational uncertainty.

This intensive Well Testing and Pressure Transient Analysis training course equips petroleum engineers, reservoir engineers, production engineers, and field professionals with the practical knowledge required to design, execute, interpret, and evaluate well tests with confidence. Participants will gain a solid understanding of pressure transient theory, reservoir flow regimes, well performance analysis, and modern interpretation techniques for a wide range of reservoir conditions.

Combining engineering fundamentals with real field applications, the course covers radial flow equations, pressure build-up and drawdown analysis, bounded and infinite reservoirs, gas well testing, fractured reservoirs, horizontal wells, and advanced PTA interpretation. Through practical exercises, industry case studies, and field examples, participants will develop the skills to analyze test data accurately, identify reservoir characteristics, and support better operational and investment decisions.
