|Title:||Integration Of Streamline Simulation And Automatic History Matching|
|Abstract:||This paper presents an integration of different methodologies for history matching of complex fields. For such cases, a fine grid model is necessary and, therefore, the simulation time is high, yielding a constraining factor because the number of simulations must be limited in such cases in order to turn the process feasible. The proposed approach combines three fundamental steps: (1) a global history match; (2) the use of streamline simulation to determine flow path among producers and injectors or between an aquifer and a producer well to facilitate the choice of regions of interest to history match individual wells; and (3) the history match of wells through the modification of the properties of the regions of interest. The first and third steps are performed using an automated history matching methodology, which uses parallel computing and traditional simulation procedure. The proposed approach is applied to a real case from an offshore field with 34 producer wells and 13 injector wells and a period of 22 years of production is available. Results showing the advantages and disadvantages of using an automated history matching in a complex field are presented. The use of streamline simulation as a support tool in such complex field history matching is also presented. Other aspects such as speedup of the process, using parallel computing, and high reduction rate of objective-function, by choosing correct regions for modification of the properties, are described in the paper. The main contribution of this paper is to show a convenient form of combining two important tools: streamline simulation and automatic history matching of complex fields.
