Improving Petrophysical Interpretation of Conventional Log by Determination of Real Bed Boundaries [PDF]
Journal of Sciences, Islamic Republic of Iran, 2017 Proper determination of bed boundaries in layered reservoirs is vital for accurate petrophysical interpretation of conventional logs. In the wellbore, logs continuously measure physical properties of reservoir while the properties change stepwise ...

Petrophysical properties across scales and compositions
, 2023 The scales at which observations from geophysical imaging are made are orders of magnitude larger than those made in field-based studies of fossil subduction and collision zones. Even more so, the determination of petrophysical properties of rocks is typically based on millimeter to centimeter-scale samples, and the so-obtained information is then used
