The Ensemble Kalman Filter (EnKF) has become a popular method in reservoir modeling.
Several publications have demonstrated the use of EnKF, and suggested further developments of the
method. In this paper, a constant flow rate no flow bounded reservoir is used to explore the
applicabity of EnKF. The reservoir modeling and the solution will be discussed and play a role as
reservoir simulator. The sequential updating will be discussed and implemented in reservoir modeling.
The conclusion is that EnKF can provide satisfactory results compared with traditional reservoir
simulation updating method
