*Abstract

This invention is a system and method of providing water management and utilization during the process of dewatering and retorting of oil shale. More specifically, the process described relates to co-producing potable and non-potable water, for various uses, during the extraction of petroleum from shale oil deposits. Generally, the process allows the production of multiple streams of waters or varying salinity and pressures at least one of which is of high enough pressure for reinsertion into geological formations or reservoirs, and another which may supply a potable water source. In one embodiment, the high pressure required for reinserting the non-potable water into geological formation or reservoirs may be utilized for producing the potable water supply. In another embodiment, the non-potable water supply may also be used for entraining and sequestering undesired emissions, such as CO2.
