... predicted petrophysical properties show similar pattern and range of values to true petrophysical properties. Unsupervised hierarchical clustering tests show hidden trends in the data that may help further improve future efforts to use ML techniques for reservoir characterization. us government...

... this relationship. In the current widely used conventional methods, it is controversial to consider the shallow section as normally pressured and at the same time extract a compaction trend from its petrophysical properties. Moreover, there is confusion about which part of the subsurface section the Effective...

..., bio-stratigraphic & reservoir data to estimate petrophysical properties and necessary modifications in conventional approach were introduced for capturing the reservoir heterogeneity and stochasticity. Hi-frequency digenetic cycle mapping at log scale and pre-stack inversion results (P & S...

..., petrophysical properties and top depth of reservoir were varied to capture the uncertainty ranges seen in the GVLA wells and analogue fields. These models captured the net-to-gross uncertainty which has the largest impact on hydrocarbons in-place and connectivity. The dynamic uncertainties were assessed using...

... in porosity; the use of two rock properties, as routinely used in cross-plotting techniques, is ambiguous; that is: more than one set of petrophysical properties result in the same rock properties. Incorporating a third independent rock property, although reduces ambiguity, does not guaranty that a set...
