Instructor: Dr. Tarek Ahmed

Designed for:

Petroleum engineers and other professionals involved in the exploration, production, and evaluation of unconventional resources.

Course Overview:

This is a comprehensive course that focuses on conventional gas reservoir performance. The course offers the practicing reservoir engineer with a full and in-depth description of the theory of transient flow analysis in gas reservoirs. The course will introduce the participants to the latest development in decline and type curve analysis for these types of reservoirs.

Participants are encouraged to bring their own laptop computer to class.
