Comprehensive Well Test Analysis Course

A detailed review of the fundamental principles and mechanisms behind well testing.
Topics include:

• Aims and advantages of well testing
• Theoretical foundations and flow regimes
• Radius of investigation
• Formation damage and skin factor
• Wellbore storage effects
• Types of pressure transient problems
• Single well pressure tests (Drawdown, Buildup, Injection, Falloff, Interference)
• Multi-rate tests (Flow After Flow, Isochronal, Modified Isochronal)
• Superposition principles

This module establishes the conceptual foundation required for professional well test interpretation and reservoir characterization.

This module focuses on analytical modeling and interpretation techniques used in well test analysis.
It covers:

• Well and wellbore storage models
• Reservoir model identification
• Boundary and geometry modeling

Participants will gain the skills to analyze pressure data, match models, and identify key reservoir characteristics such as permeability, skin, and boundary effects.

An in-depth overview of the operational aspects of well testing, covering both surface and downhole components.
You will learn about:

• Surface facilities and test setups
• Downhole tools and equipment functionality
• Surface fluid sampling and testing procedures

This section emphasizes practical understanding, ensuring participants can relate theoretical knowledge to real field applications and operational challenges.

The final module focuses on data interpretation using Saphir software.
After a complete walkthrough of the software environment, six case studies are analyzed, covering:

• Homogeneous reservoir models
• Limited entry behavior
• ESP (Electric Submersible Pump) data for pressure transient analysis
• Gas well analysis

By the end of this module, participants will be able to confidently perform well test interpretation using industry-standard tools and apply analytical reasoning to various well and reservoir types.

By completing this course, you will:

• Understand the complete workflow of well testing — from theory to operation and analysis
• Interpret pressure transient data for various reservoir and well conditions
• Apply analytical models to evaluate reservoir and boundary behavior
• Use specialized software to perform professional well test analysis
• Strengthen your ability to diagnose formation damage, boundaries, and production performance
