Intelligent Fields: A New Era for Oil and Gas Field Development


Published on

This presentation was given to the faculty of The College of Engineering and Petroleum in Kuwait University on 3rd December 2008. It\'s a bit general since it was given to the whole faculty and students not just Petroleum professionals.
