Reproducing slugging oscillations of a real oil well

Authors: Florent Di Meglio, Glenn-Ole Kaasa, Nicolas Petit, Vidar Alstad, 49th IEEE Conference on Decision and Control, December 2010, Atlanta DOI: 10.1109/CDC.2010.5717367
This paper addresses the problem of reproducing oscillations generated by the well-known slugging phenomenon in multiphase flow. Reported investigations show how to determine the parameters of a recently proposed ordinary differential equations system, so that it captures the charac- teristics of actually observed slugging oscillations. A tuning procedure based on the mathematical properties of the model is presented. It is then applied to a test case consisting of a real oil well located in the North Sea. An observer using only topside measurements allows asymptotic reconstruction of critical variables such as the downhole pressure.
