The first day of this class will introduce students to some of the fundamentals of reservoir engineering. Participants will learn about the role of reservoir engineering in exploration and production as well as how reservoir engineers interact with other engineering disciplines. Reservoir environment and formation properties will also be discussed to include, structure and properties of rocks, porosity, permeability, compressibility, wettability, and capillary pressure. Participants will learn about the identification of contacts as well as effective and relative permeability and how to measure relative permeability. The definition of reservoir pressure and the determination of pressure gradients will also be discussed.
- Reservoir and surface conditions

- Estimating gas, oil, and water properties from correlations
- Application of deviation factor to ideal gas law
Day two of this course will cover reservoirs and surface conditions. Some topics that will be discussed include formation volume factor, viscosity, solution gas – oil ratio, API gravity and specific gravity. Estimating gas, oil, and water properties form correlations will also be covered. Participants will also learn about the application of the deviation factor to ideal gas law.

On day four of this course, participants will learn about reservoir drive mechanisms and the concept of a reservoir as a single tank. The definition of the material balance equation will also be covered, along with a reservoir drives limitations on the use of the material balance equation. During this day, participants will examine the water influx and the use of fractional flow equations. Participants will learn about the recovery of a reservoir on this day along with determining the initial and recoverable oil and gas.
