Applied Reservoir Engineering

ABOUT THE COURSE

This course represents the core of our reservoir engineering program and the foundation for all future studies in this subject. A ten-day, in-depth study of the subject is presented. Numerous engineering practices are covered ranging from fluid and rock properties to simulation and field development planning. Proficiency in using Microsoft Excel to perform calculations and make graphs is desirable. Reservoir engineering is also presented in the context of a modern, multi-disciplinary team effort using supporting computer technology.

An extensive manual and set of references are included. This course has been taught for many years on a worldwide basis. It has been continuously updated and improved by a team of experienced reservoir engineering consultants who spend most of their time working on major reservoir engineering projects and field studies. 

This course includes the use of computers, which are provided at additional cost, for each two participants.
