Method of updating a geological model of a reservoir with the aid of dynamic data

摘要

The method involves constructing an initial map of petrophysical properties using a geostatistical simulator and static data, e.g. logs. A combined set of gradual pilot points is constructed by combining the initial and complementary sets of gradual pilot points. Values of properties are modified by constraining the map, and the combined set is modified. The combined set construction and the modifications are performed until a stop criterion is reached to integrate dynamic data, e.g. production data, by optimizing the map. A geological reservoir model is updated by associating the map with a grid.
