Gas Engineering: Gas Deliverability Analysis | Chapter 1

This video provides a structured and practical guide to gas well deliverability analysis used in reservoir engineering and production operations. It covers the full workflow from testing methods to interpretation, with clear links between theory and field application. Topics covered: Gas well deliverability fundamentals Pressure losses across reservoir, wellbore, and surface systems Darcy and non Darcy flow behaviour in gas wells Absolute Open Flow AOF concept and calculation Deliverability equations and log log plotting method Multipoint well testing and data interpretation Testing methods explained: Conventional flow after flow test Isochronal testing with controlled flow and shut in cycles Modified isochronal testing using fully transient data Comparative analysis of test methods based on: Stabilisation behaviour Testing time requirements Data quality and reliability Applicability to different reservoir conditions Deliverability analysis workflow: Data quality assessment Model selection using empirical and analytical methods Parameter estimation using field data AOF and inflow performance relationship construction Production forecasting and optimisation This content is designed for petroleum engineering students, reservoir engineers, and production engineers who require a clear, applied understanding of gas well testing and deliverability modelling. The focus is on decision quality.
