Feedback control is not new in the Exploration and Production (EP) industry. Almost all the units in a hydrocarbon production station are controlled with an automatic controller of some sort. However, the above statement does not hold true for any equipment outside the boundaries of production stations such as production wells and injection wells. The aim of this paper is to focus on an area that has been for a long time considered outside the process control engineering domain. Driven by positive trials with clear demonstrated benefits, this picture is changing at Petroleum Development Oman (PDO). This paper will show how simple control schemes are having a great impact on PDO’s oil production optimization and gas constraint reduction with the minimum of cost. The paper will present two utilizations of such control schemes and how much value PDO is reaping from these two implementations. The first is employed on production wells that exhibit an unstable behavior and the other is used for water injection systems. Finally, the challenges facing these technologies are discussed.
