The wettability of reservoir rock is a crucial factor controlling displacement efficiency and
ultimate oil recovery. In this study, the wettability of carbonate reservoir rocks as a function of
temperature has been studied by measuring the Amott index to water using an X-ray
computed tomography (CT) scanner. The cores for the Amott test were carefully prepared
and aged at reservoir conditions to achieve restoration of reservoir wettability. The reservoir
cores contain dolomite and chert based on the results of Fourier transform infrared …
