The non-volatile mercury is extrac­ ted into the water phase forming mercury a rich wastewater, yielding a treated crude oil having less at than 50% of the original non­ volatile mercury level. The wastewater can disposed or recycled by injection into reservoir. In a one embodiment, the water stream consists essentially of produced water.
