A methodology is proposed that integrates historical production data into large reservoir models by the local updating of the permeability field. The focus is on conditioning a proposed initial model to injection/production rate and pressure history in an iterative fashion. Integrating flow simulation and kriging algorithms within an optimization process based on linearized formulas of reservoir behaviour...
The idea of conditioning by kriging is well known in theory and practice. It has been used for conditioning the realizations from unconditional simulation techniques such as the moving average and the turning bands simulation approaches. The basis of the conditioning by kriging approach is to use the same variogram for both the unconditional simulation and the kriging. In this paper, the focus is...
