... of Mexico. A prediction accuracy of 85% was obtained, and the associated uncertainties were evaluated. Although our current database is not complex and large enough to mimic the realworld scenario, it demonstrates the importance of understanding the uncertainties from data and model. Such uncertainties...

... of the interpretive database. Database issues include proper loading and QC of well information such as headers, deviations, logs, and well tops. Similar consideration must be given to the seismic data. The points above are best evaluated in context of employing deliverables obtained from anisotropic depth imaging...

... and exploit vast amounts of data more efficiently for shorter turnaround times. For this reason, we proposed a pilot well log database in HDF5 (Hierarchical Data Format) format that can be continuously updated and provide versatility for data preparation to carry out further analysis. Similarly, through three...
