Abstract
The stability of water-in-crude oil (or model crude oil) emulsions was determined by means of separation/sedimentation tests and high voltag e destabilization tests. First the impact of the state of solvation of asphaltenes on their ability to stabilize emulsions were studied. Sec ondly, we analyzed the role of naturally occurring waxes in the stabil ization of emulsions. Finally, the emulsion stability when both asphal tenes and waxes are involved was investigated.
