Description

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

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