Currently, carbonate rocks account for more than half of the world's hydrocarbon reserves. However, this particular type of rock has a number of features that make it a complex challenge for characterization and management of an oil field. The challenges related to production from carbonates have, as a key factor, the fact that 80%-90% of them present oil or neutral wettabilities, leading at the end to a low oil recovery factor (RF). This paper presents the recent advances in nuclear magnetic resonance (NMR) to quantify and characterize carbonates wettability and how much the information derived from this tool can be used in the quantification of success of advanced enhanced oil recovery methods in such rocks
