Abstract

In this paper we study two classes of instabilities occurring in practical applications of gas-lifted oil wells. The model underlying our analysis stresses the role of the feedback interconnection. It involves an infinite dimensional linear system coupled to a first order dynamics. Stability analysis is performed through the small gain theorem and the relevance of the derived conclusions is discussed in terms of state of some of state of the art well production knowledge
