This paper considers an approach to design a fuzzy logic controller to detect incipient abnormal production of wells in a reservoir. The daily operation of an oil and gas production system requires many decisions, which may affect the volumes of oil produced and the cost of production oil. These decisions are taken at different levels in the organization, but eventually they will reach the phys...

This overview of different applications of CBR in petroleum engineering is based on a survey and comparative evaluation of different successful applications of CBR. The number of papers and research groups is indicative of importance, need, and growth of CBR in different industries. Applicationoriented research in the area of case based reasoning has moved mature research results into practical...

Low pressure oil wells can be made to flow by the injection of gas into the well. The resulting flow from the well increases discontinuously with the amount of gas injected. A common way to model this is by introducing integer variables which results in a MINLP formulation. Such a problem can be solved efficiently by a specialised Branch & Bound code. However for more than about 200 wells a com...
