This three-day short course will examine methods available to forecast production and estimate reserves in unconventional (low to ultra-low permeability, hydraulically fractured, shale gas) reservoirs, and will identify the strength of weaknesses of commonly used methods. Most of the course will deal with extrapolation of decline trends (decline curve analysis), using the Arps model, the Arps model modified by use of a minimum terminal decline, Advanced Decline Curve Analysis (Fetkovich), the Stretched Exponential Model, Long-Duration Linear Flow, the Duong Model, and Blasingame’s ‘Continuous EUR Method.’ The course will also include a review of fundamental fluid flow theory that supports several production forecasting models. There will be numerous examples illustrating application of principles.
