Chris Fair provides a comprehensive overview of well testing principles and techniques, tailored for geologists and geophysicists in this presentation. It focused on explaining well test interpretation, including the analysis of pressure and rate data to understand well and reservoir behavior. The presentation demystified common terms and concepts in well testing, such as permeability, skin, and damage, and discusses how these factors impact well performance. The goal was to bridge the gap between geological understanding and well test data, enhancing interdisciplinary collaboration in reservoir management.
