Analysis of porosity parameter with involvement of elements of regional petrophysics (electrofacies) and clayness type

Горные науки и технологии, 2016
The most important estimation parameter – the open porosity coefficient (Kp) - in petrophysical laboratories is, as a rule, determined for the productive formation on the whole and without taking into account its regional heterogeneity.

An integrated approach to address the heterogeneity of carbonate gas reservoirs using high resolution saturation height function

Journal of Petroleum Exploration and Production Technology
Accurate water saturation (Sw) modeling in carbonate reservoirs remains a persistent challenge due to complex pore structures and facies heterogeneity that compromise the reliability of traditional resistivity-based techniques.
