ABSTRACT: The evaluation of granulometric and petrophysical parameters conducted on drilling cuttings from South-Comoé (Adiaké and Aboisso) aims to characterize the Continental Terminal formations. This study also contributes to a better understanding of the geological formations in the studied localities. The granulometric and petrophysical parameters were determined using the statistical method of moments and laboratory tests. Furthermore, Python software was utilized to represent the various parameters and establish significant correlations between them. At the granulometric level, the sands are predominantly coarse and moderately to poorly sorted. Moreover, they exhibit positive skewness and are leptokurtic. Regarding the petrophysical parameters, total porosity values range from 33.33% to 55.14%, while bulk density values oscillate between 1.121 and 1.67 g/cm3. The proportion of clay matrix varies between 0.53% and 44%. Correlation analysis reveals that total porosity increases while bulk density decreases. High total porosity is characteristic of a high clay proportion, fine grain size, poor sorting, and positive or negative skewness.
