The uncertainty of AVA attributes along the wells

We generated the histogram cube by using 50 multiple realizations. From the histogram, we found the AVA attributes along well B have obviously bigger avearage uncertainty than well A and well C in the depth range we studied. Figure 5 and Figure 6 show the depth slice at 3.20km and 3.43km respectively from histogram cube. The low shale volume along the well B in the depth window make us guess the low shale shale/sand ratio causes hig AVA uncertainty here.
