Toward a Reliable Quantification of Uncertainty on Production Forecasts: Adaptive Experimental Designs

Abstract: Résumé -Vers une quantification fiable des incertitudes sur les estimations de production : plans d'expériences adaptatifs -La quantification des incertitudes est une phase essentielle dans l'évaluation des réservoirs pétroliers. La précision des estimations de production est fortement liée à l'incertitude sur les variables qui contrôlent les performances du réservoir (perméabilité, contact huile-eau, etc.). Le problème est complexe parce que l'effet des variables sur les performances du réservoir est souvent … Show more

“…Moreover, the presence of potential non-linear effects and interactions between the OF and the uncertain input parameters requires the use of more advanced and efficient RS than a simple linear regression. Previous works such as [5][6][7][8][9][10][11] describe how Gaussian Process (GP), possibly associated with adaptive design, can be used to approximate outputs of a fluid flow model. In this paper, we use a RS based on GP technique combined with an adaptive design as detailed in [12] and roughly described below.…”

“…It is classically assumed that the production data follows a Gaussian uncertain model and that the fluid-flow reservoir simulator is deterministic. In that case, the likelihood function is given by (see [18]): (10) where f is the simulator, C data the covariance matrix of the production data and c a normalization constant.…”

“…Reference [7], for instance, uses Gaussian processes to approximate key outputs of numerical models from a fixed number of simulations. Adaptive design strategies have also been proposed instead of fixed designs to improve Gaussian process approximations for given responses [9].…”
