METHOD, SYSTEM AND APPARATUS FOR REAL-TIME RESERVOIR MODEL UPDATING USING ENSEMBLE KALMAN FILTER |
摘要 |
<p>A method, system and apparatus for real-time reservoir model updating using ensemble Kalman filters is described. The method includes a conforming step for bring bringing static and dynamic state variables into conformance with one another during a time step of the updating. Also, an iterative damping method is used in conjunction with the conformance step to account for nonGaussian and nonlinear features in a system. Also, a re-sampling method is described which reduces the ensemble size of reservoir models which are to be updated.</p> |
