Microstructural characterization of a Canadian oil sand [PDF]
The microstructure of oil sand samples extracted at a depth of 75 m from the estuarine Middle McMurray formation (Alberta, Canada) has been investigated by using high resolution 3D X-Ray microtomography ($\mu$CT) and Cryo Scanning Electron Microscopy ...

Improving Petrophysical Interpretation of Conventional Log by Determination of Real Bed Boundaries [PDF]
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 ...

Updating the petrophysical model of a thin-layered clay reservoir, taking into account the identified lithofacies features [PDF]
The article presents a study on the establishment of geological and facies conditions for the formation of a sandy-silty-clayey reservoir based on core analysis and linking the information obtained with neighboring areas.

Petrophysical properties across scales and compositions
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

The effect of eclogitization of crustal rocks on the seismic properties on variable scales: Implications for geophysical imaging of eclogitization at depth [PDF]
Plate tectonics shapes the face of the earth and subduction and collision zones are among the most important features on Earth. Here, crustal material is recycled into the mantle or integrated into growing orogens.
