In this paper, we experimentally compute water adsorption isotherms and perform sensitivity analysis on the impacts of (i) wettability levels, (ii) types of rock components, and (iii) concentrations of mineral constituents on water adsorption. We synthetically change the wettability of pure...

... of the magnetic susceptibility signal from ferrimagnetic minerals (e.g., magnetite) or ferromagnetic metallic contaminants (e.g., from the drill bit and casing wear) since these components should saturate in high fields. This is important since permeability in this study is controlled by paramagnetic clays like...

...). They used Si, Mg, Fe, Ca, and Al as input curves (Fig. 2). In their study, the major minerals were identified as (1) olivine (Mg, Fe) in the dunite zone; (2) plagioclase feldspar, olivine (Mg, Fe), and clinopyroxene in the gabbro zone; (3) olivine (Mg, Fe) and orthopyroxene (Mg, Fe) in the harzburgite zone...

... and Pellerin, 2007). Further compaction and metamorphosis would generate a schist. Such a definition by grain size can be augmented by defining clay minerals in quantity and type, aiming to characterize sorption and diffusion processes. Most oilfield petrophysicists are concerned with the amount of clay...

Additionally, two postulated low-carbon areas supporting renewable energy generation are briefly examined—downhole quantification of strategic minerals...

In particular, the magnetic susceptibility of paramagnetic minerals (such as the clay illite, which often controls the fluid permeability of reservoir rocks) decreases with increasing temperature.
