The petrophysical andpetrographical properties ofhyaloclastite deposits: Implicationsfor petroleum exploration

, 2014
Offshore sequences of volcaniclastic rocks (such as hyaloclastite deposits) are poorly understood in terms of their rock properties and their response to compaction and burial.

Petrophysical Property Prediction from Seismic Inversion Attributes Using Rock Physics and Machine Learning: Volve Field, North Sea

Applied Sciences
An accurate petrophysical model of the subsurface is essential for resource development and CO2 sequestration. We present a new workflow that provides a high-resolution estimate of petrophysical reservoir properties using seismic data with rock physics ...

Petrophysical properties and durability of granites employed as building stone: a comprehensive evaluation

, 2014
The use of a rock as a building stone is conditioned by several factors, from its aesthetic characteristics to its petrophysical properties. Even though the latter are taken into consideration, only a few of them are usually assessed. The purpose of this

Petrophysical Evaluation of Gas shale Reservoirs

, 2015
For many years, shale formations were viewed as a hydrocarbon source rock or cap rock. Due to this traditional point of view, only geochemical analysis has been routinely performed on the shale layers.
