Claim 16:
17. A method, comprising:
receiving one or more oilfield brine feedstocks from one or more hydrocarbon-producing wells;
detecting, using one or more sensors, one or more properties of the one or more oilfield brine feedstocks;
pumping a portion of the one or more oilfield brine feedstocks through a desalination system using pressure generated by a pumping system;
desalinating the portion of the one or more oilfield brine feedstocks to produce desalinated water and saltwater;
determining a ratio of the saltwater and the desalinated water to be injected into one or more saltwater disposal (SWD) wells based at least in part on the one or more properties of the one or more oilfield brine feedstocks;
injecting a first stream of the saltwater and a second stream of the desalinated water into the one or more SWD wells using the pressure generated by the pumping system; and
controlling the injection of the first stream of the saltwater and the second stream of the desalinated water into the one or more SWD wells based at least in part on the determined ratio.
