Method for measuring wettability

摘要

A computer-implemented method for determining wettability characteristics of a fluid-bearing porous medium, the method comprising the steps of:
receiving measurement data indicative of a relaxation time of fluid present in the porous medium at a defined fluid saturation;
receiving reference data indicative of one or more reference relaxation times of the fluid; and
calculating a wettability index on the basis of differences between the received measurement data and the received reference data, said wettability index being indicative of the wettability characteristics of the porous medium at the defined fluid saturation.
