Oil and Gas Engineering Training Courses

Transient Well Test Analysis


The course covers well test objectives and concepts; classical methods for drawdown and build-up analysis, gas well testing, IPR & AOF analysis, well test validation. The course first introduces the purpose of well testing and the basic methodology. Essential reservoir rock and fluid properties which are essential for analyzing well tests will be reviewed and the theory and fundamental equations are covered before introducing specific analysis techniques for oil and gas reservoirs. Operational aspects are covered in terms of sampling and the use of specialized testing equipment.
