Fundamentals of Reservoir Engineering

This course will introduce participants to the basics of reservoir engineering. It will cover the role of reservoir engineers in exploration and production. Participants will also learn about fluid and rock properties used in reservoir engineering applications and the fundamental concepts of fluid flow in porous media. Multiphase situations, types of oil and gas reservoirs, reservoir drive mechanisms, the basics of material balance and decline curve analysis, and reserve definitions will also be discussed.

Other important concepts that will be covered include the reservoir life cycle, reservoir environment and formation properties, Darcy’s Law, and API correlations. By the end of the course, participants will have gained a foundational understanding of reservoir engineering that they can use while moving forward in their training.

    • Definition of reservoir pressure
    • Determination of pressure gradients 

    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.  The definition of reservoir pressure and the determination of pressure gradients will also be discussed.

    Day 2

    Reservoir Conditions 

    • Reservoir and surface conditions
    • Formation volume factor, viscosity, solution gas-oil ratio, API gravity, specific gravity
    • Estimating gas, oil, and water properties from correlations
    • Application of deviation factor to ideal gas law
    • Darcy's Law and fundamentals of fluid flow
    • Relative permeability concept

    Day two of this course will cover PVT properties of reservoir fluids.  Fundamentals of fluid flow and Darcy Law will also be covered.  The day will end with participants discussing the relative permeability concept.

    Day 3

    Reservoir Fundamentals

    • Overview of well testing techniques
    • Use of well testing
    • Inflow performance and basics of Nodal Analysis

    Participants will cover reservoir fundamentals to include, fluid flow, Darcy’s Law, applications in radial flow, stratified reservoirs, and damage zone.  Expansions for gas wells applications, principles of well testing in reservoir characterization and the estimation of average pressure will also be discussed.  This day will introduce participants to the application of diffusivity equation and the application of line source solution.  The participants will also learn about the use of well testing in determining average reservoir pressure, productivity index, permeability, and skin effect. The day will end with the participants learning inflow performance and nodal analysis.

    Day 4

    Reservoir Drive 

    • Reservoir Drive Mechanisms
    • Principles of Material Balance Analysis
    • Use of fractional flow equations
    • Immiscible displacement concepts
    • Recovery concepts

    On day four of this course, participants will learn about reservoir drive mechanisms and the concept of a reservoir as a single tank along with a reservoir drives limitations on the use of the material balance equation.  During this day, participants will examine the water injection and the use of fractional flow equations.  Participants will also discuss the recovery factors of different drive mechanisms.

    Day 5

    Reserve Estimation 

    • Definition of reserves
    • Recovery factor-API Correlations
    • Estimation of oil-in-place and gas-in-place

    On the last day, participants will discuss the definition of reserves and the recovery factor – API correlation.  During this day, estimation of oil-in-place and gas-in-place concepts will be covered.  The day will end with hands on exercises on RF estimations.
