Abstract
Systems comprising a main tubular coupled to a pump and extending from a surface into a subterranean formation, wherein produced bulk fluid is pumped to the surface, and wherein the bulk fluid comprises at least water and a hydrocarbon, and has certain constituent parameters; a storage container for retaining the bulk fluid; a sampling tubular in fluid communication with the main tubular for sampling the bulk fluid, thereby forming at least one sampled fluid; and a dosing system coupled to the sampling tubular and configured to receive the sampled fluid, the dosing system configured to determine a constituent parameter of the sampled fluid, identify a type and concentration of separating surfactant to include in the bulk fluid to obtain a hydrophilic-lipophilic deviation (HLD) substantially equal to 0, and introduce the identified type and concentration of the separating surfactant into the storage container retaining the bulk fluid.
