Who Should Attend

The course will be particularly important for reservoir engineers interested in production forecasting in low permeability reservoirs using techniques that lead to the ability to forecast production for large numbers of wells in short periods of time. Other engineers, geoscientists, reserves analysts, and managers of low-permeability assets will also deepen their understanding of both appropriate and inappropriate forecasting techniques and how to select appropriate methodology.


Fluid flow fundamentals, Empirical and semi-theoretical decline models including Arps, Fetkovich, Stretched Exponential, Power-Law, Transient Linear Flow, and Duong, Diagnostic plots for flow regime identification, pressure normalization of rate data, recommended workflow for pressure-rate-time production data analysis, Typical Well Production Profile (Type Well, aka Type Curve) construction

Course Content

This course will provide training in production forecasting and reserves estimation for low-permeability resource plays (such as shales) using simple, rapidly applied decline models favored by the industry for routine forecasting. Recommended methodology will be based on fundamental fluid flow theory rather than only on experience with different modeling techniques. The course will conclude with a comparison of decline models and a suggested workflow applicable to a wide variety of models and soundly grounded in fundamentals.

There are various ways to forecast production and estimate the size of unconventional oil and gas reservoirs. In this course, you will learn the strengths and weaknesses of each decline model and how to develop reliable forecasts.
