1. A method comprising:
receiving one or more oilfield brine feedstocks from one or more producing wells producing hydrocarbons from a subterranean formation;
determining if a respective concentration of the one or more oilfield brine feedstocks is above a threshold;
in response to determining that the respective concentration of the one or more oilfield brine feedstocks is above the threshold, processing at least a portion of the one or more oilfield brine feedstocks to produce desalinated water and a salt slurry suspension;
providing the desalinated water for surface use, surface discharge, or both; and
reinjecting the salt slurry suspension into the subterranean formation, a different subterranean formation, or both, wherein the salt slurry suspension comprises solid salts and saturated brine.
