Course Overview

This course covers the planning, execution, and interpretation of well tests, equipping participants with the skills to design effective tests, acquire quality data, and analyze results for reservoir characterization and well performance evaluation.

Day-by-Day Outline

Day 1 – Well Test Fundamentals & Objectives

- Purposes of well testing: reservoir properties, deliverability, boundaries
- Types of tests: drillstem, production, build-up, interference
- Pressure transient theory basics
- Planning considerations: duration, rates, shut-in times
- Exercise: Define objectives and type of test for different reservoir scenarios

Day 2 – Well Test Design & Execution

- Gathering well and reservoir data for test design
- Designing flow and shut-in sequences
- Well test tools and surface equipment
- Ensuring data quality: sampling rates, gauges, and calibration
- Workshop: Design a multi-rate drawdown test for a gas reservoir

Day 3 – Pressure Transient Analysis Principles

- Flow regimes and diagnostic plots
- Theoretical solutions: infinite-acting, boundary-dominated, skin effects
- Superposition and type curve matching
- Introduction to specialized software for analysis
- Exercise: Match build-up data to type curves for permeability estimation

Day 4 – Advanced Test Interpretation & Complex Reservoirs

- Analysis in fractured, heterogeneous, and multi-layer reservoirs
- Dual-porosity and dual-permeability models
- Deconvolution techniques and modern interpretation methods
- Identifying reservoir boundaries and faults
- Workshop: Analyze data from a test in a naturally fractured reservoir

Day 5 – Case Studies & Integrated Well Test Applications

- Integrating well test results with other reservoir data
- Using tests to update reservoir models
- Field case studies: successes, challenges, and lessons learned
