Abstract
A method, implemented on a computer, for calculating vertical trend curve uncertainty of spatially correlated reservoir data. The method includes inputting, into the computer, a sample reservoir data comprising correlated data; applying, using the computer, a variogram to the sample reservoir data to select a plurality of subsets of data, the subsets of data being substantially less correlated than the sample reservoir data; and applying, using the computer, a bootstrap process on each of the plurality of subsets of data to obtain a plurality of bootstrap data sets from each of the plurality of subsets of data. The method further includes calculating vertical trend curves for each of the obtained plurality of bootstrap data sets, ranking the vertical trend curves by using a selected statistical parameter to obtain ranked vertical trend curves, and characterizing the uncertainty based on the ranked vertical trend curves.
