Fundamentals of Reservoir Engineering

Duration: 5 days

Course Objective: This course offers the know-how knowledge to make the everyday decision-making become simple: How to plan data acquisition? What kind of data is needed? How to use the data as a reservoir management tool? How to increase ultimate recovery & projects' NPV's? The theory concepts will be covered to assist reservoir and exploitation engineers to effectively understand and perform their main tasks; determine oil and gas reserves and maximize hydrocarbon recovery under primary, secondary and tertiary schemes with emphasis on the bottom line results. Other topics such as well test analysis, horizontal well applications, and reservoir drives will be covered. Interesting class examples using actual field data will reviewed. A course hand-out which is an excellent reference will be provided.

Audience: This course is aimed at reservoir, petroleum and exploitation engineers/technologists, geophysicists, and geologists who are involved in field development and exploitation.
