Claim One:
1. A method for characterizing a reservoir of interest comprising: (a) obtaining a first reservoir fluid sample at a first downhole measurement station within a borehole that traverses the reservoir of interest: (b) performing downhole fluid analysis of the first reservoir sample to characterize compositional components of the first reservoir sample: (c) predicting compositional components with depth using the results of the downhole fluid analysis of (b); (d) obtaining a second reservoir fluid sample at a second downhole measurement station within the borehole: (e) performing spectrophotometry on the second reservoir fluid sample to derive spectrophotometry measurement data related to the second reservoir fluid sample: (f) deriving predicted spectrophotometry measurement data for reservoir fluid at the second downhole measurement station based upon asphaltene concentration of the compositional components with depth predicted in (c) and correlation between asphaltene concentration and spectrophotometry measurement data: (g) comparing the spectrophotometry measurement data of (e) and the predicted spectrophotometry measurement data of (f); and (h) generating user output that characterizes the reservoir of interest based upon the comparing of (g).
