Claim One:
1. A method, implemented on a computer, for calculating vertical trend curve uncertainty of spatially correlated reservoir data, comprising: inputting, into the computer, a sample reservoir data comprising correlated data from a reservoir volume of interest; 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; 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; 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; characterizing a vertical trend curve uncertainty based on the ranked vertical trend curves; and using the vertical trend curve uncertainty to characterize the reservoir volume of interest and estimate one or more properties of the reservoir volume of interest, the properties comprising at least one of porosity volume, original oil in place, net rock volume, or combinations thereof.
