Calcium Ion Bridging of Aqueous Carboxylates onto …
Release of crude oil from reservoir rock by low-salinity waterflooding is thought to occur by decreasing the advancing crude oil/brine/rock water contact angle to depin three-phase contact lines (i.e., by increasing reservoir water wettability). Crude oil likely adheres locally to reservoir rock asperities by deposition of asphaltene agglomerates formed at the crude oil/brine interface
