Abstract
The chemical distance between fingerprints of fluid samples from a reservoir can be determined using statistical analyses. Upon performing chromatographic analyses on fluid samples from the reservoir, certain peak height values from the chromatograms are selected, and various peak height ratios are formed using the selected peak height values. An experimental distribution of the differences between the peak height ratios is produced using two chromatograms from one of the fluid samples and a theoretical distribution of the differences of the peak height ratios are produced assuming the two chromatograms are from the one of the fluid samples. An uncertainty model of the peak height values is optimized and the parameters of the optimized uncertainty model are used to modify the theoretical distribution. The interquartile ranges of the experimental distribution and the modified theoretical distribution are determined and the chemical distance between the samples is determined using the interquartile ranges.
