Course Overview

Day-by-Day Outline

Day 1 – Fundamentals of Well Testing

•  Objectives of well testing: reservoir characterization, productivity, boundaries
•  Types of tests: drawdown, buildup, DST, injectivity
•  Basics of pressure transient behavior in radial flow
•  Planning well tests: equipment, duration, data quality
•  Exercise: Design a basic buildup test plan for a vertical well

Day 2 – Diagnostic Plots and Flow Regime Identification

•  Log-log, Horner, MDH, and Bourdet derivative plots
•  Identifying flow regimes: wellbore storage, radial flow, boundary effects
•  Concepts of skin, wellbore damage, and stimulation interpretation
•  Workshop: Generate diagnostic plots from field data and interpret flow regimes

Day 3 – Interpretation of Complex Tests

•  Multi-layer and dual-porosity reservoir responses
•  Fractured reservoir well tests
•  Effect of partial penetration and anisotropy
•  Slug, interference, and pulse testing
•  Exercise: Analyze a buildup test in a fractured carbonate reservoir

Day 4 – Modern Tools and Software Applications
