Quantification of Uncertainty Due to Subgrid Heterogeneity in Reservoir Models

Okano, H; Pickup, G E; Christie, M A; Subbey, Sam; Sambridge, Malcolm


Due to the lack of data, a reservoir engineer needs to calibrate unknown petrophysical parameters based on production history. However, because the observations cannot constrain all the subsurface properties over a field, production forecasts for reservoirs are essentially uncertain. In general, many parameters of the model must be adjusted in the history-matching process, and the amount of computation required to solve the inverse problem may be prohibitive. To address this issue, we proposed...[Show more]
