Rebuilding and Recalibrating an Existing Reservoir Model

A007 REBUILDING AND RECALIBRATING AN EXISTING RESERVOIR MODEL Abstract 1 The increasing computer power and the recent developments in history-matching can motivate the re-examination of previously built reservoir models. To save engineer and CPU times we develop four distinct algorithms which allow for rebuilding an existing reservoir model without restarting the reservoir study from scratch. These algorithms involve techniques such as optimization relaxation Wiener filtering or sequential reconstruction. Basically they are used to identify a random function and a set of random numbers. Given the random function the random numbers yield a realization which is pretty close to the existing
