#### PEGN414 - WELL TEST ANALYSIS AND DESIGN:

This course covers the fundamental concepts of well-test analysis and design with applied examples. Drawdown and Buildup tests in liquid wells are discussed in detail and the straight-line and curve matching analysis procedures are introduced. Computerized analysis with commercial software packages is demonstrated and students are assigned example problems. Extensions of the procedures to gas well tests are also provided. Analyses of variable-rate and multi-rate tests are discussed. Transient pressure analysis of vertical, fractured, horizontal, and slant wells are covered.

#### PEGN 505: HORIZONTAL WELLS: RESERVOIR AND PRODUCTION

This course covers the fundamental aspects of horizontal well reservoir and production engineering with special emphasis on the new developments. Each topic covered highlights the concepts that are generic to horizontal wells and draws attention to the pitfalls of applying conventional concepts to horizontal wells without critical evaluation. There is no set prerequisite for the course, but basic knowledge on general reservoir engineering concepts is useful.

#### PEGN 601A: APPLIED MATHEMATICS OF FLUID FLOW IN POROUS MEDIA

This course is intended to expose petroleum-engineering students to the special mathematical techniques used to solve transient flow problems in porous media. Bessel’s equation and functions, Laplace and Fourier transformations, the method of sources and sinks, Green’s functions, and boundary integral techniques are covered. Numerical evaluation of various reservoir engineering solutions, numerical Laplace transformation and inverse transformation are also discussed.

#### PEGN 615 A SHALE RESERVOIR ENGINEERING

Fundamentals of shale-reservoir engineering and special topics of production from shale reservoirs are covered. The question of what makes shale a producing reservoir is explored. An unconventional understanding of shale-reservoir characterization is Geological, geomechanical, and engineering aspects of shale reservoirs are explained. Well completions with emphasis on hydraulic fracturing and fractured horizontal wells are discussed from the view-point of reservoir engineering. Darcy flow, diffusive flow, and desorption in shale matrix are covered. Contributions of hydraulic and natural fractures are discussed and the stimulated reservoir volume concepts is introduced. Interactions of flow between fractures and matrix are explained within the context of dual-porosity modeling. Applications of pressure-transient, rate-transient, decline-curve and transient-productivity analyses are covered. Field examples are studies.
