... in Rio de Janeiro, Brazil, May 18-22, 2024. ABSTRACT The Thomas-Stieber method has been widely used to evaluate thin-bedded clastic reservoirs by accounting for the distribution of clay minerals within the rock matrix. In such reservoirs, clay content has a profound impact on porosity and, consequently...

The ability to reduce the dimensionality of the system through the definition of ad-hoc mineral assemblages enables...
