Enhanced Oil Recovery: Fundamentals and Applications (RES31)

    Description

    This course builds an understanding of why EOR is important and discusses the various EOR mechanisms in detail.

    Course Level: Skill
    Instructor: Todd Hoffman

    Designed for you, if you are...

    • A petroleum engineer who needs knowledge of fundamental and practical aspects of enhanced oil recovery
      To get the most out of the class you should have a prior understanding of basic reservoir engineering principles.

    How we build your confidence

    • We will employ various screening criteria to determine which EOR process is right for your reservoir
    • We will define important parameters for all techniques and estimate recoveries for the different EOR techniques using simplified analytical methods
    • Field examples are used throughout the course to enhance understanding of the course material

    The benefits from attending

    By the end of the course, you will feel confident in your understanding of when and where it is appropriate to use EOR techniques from each of the three main processes thermal, miscible, and chemical.

    These techniques include CO2 and hydrocarbon miscible gas injections practices, chemical technologies of polymer, surfactant and alkali-surfactant floods, and thermal methods of steam injection and in situ combustion, along with other commercial and near-commercial technologies.

    For each technique, participants will learn how to:

    • Calculate injection requirements for a reservoir
    • Estimate the reservoir response and recovery
    • Design wells, surface installations and monitoring systems
