Course Objectives		1. Basic concepts, equations, and methodologies used in designing, interpreting and analyzing pressure transient formation and well tests. 2. Modern interpretation and analysis tools such as pressure-derivative, deconvolution, and automated type-curve matching methods for analyzing test data 3. Analysis of pressure data from complex well and reservoir systems such as horizontal wells, slanted wells, hydraulically fractured wells, naturally fractured, and layered reservoirs. 4. Evaluation of uncertainties in identifying the appropriate interpretation model(s) and estimated parameters.
