Produced water is the water associated with hydrocarbons during oil and gas extraction. Efforts to enhance produced water management include developing novel membrane materials for oil-water separation. This study developed a protocol for preparing synthetic solutions representing actual produced water characteristics and behavior, enabling performance comparisons of different oil-water separation membranes at the bench scale level. The prepared recipe was proven to be reproducible, homogeneous, stable, and comparable to actual produced water field samples.
Produced water (PW) is the water associated with hydrocarbons during the extraction of oil and gas (O&G) from either conventional or unconventional resources. Existing efforts to enhance PW management systems include the development of novel membrane materials for oil-water separation. In attempting to evaluate these emerging physical separation technologies, researchers develop various formulations of test solutions aiming to represent actual PW. However, there is no clear scientific guideline published in the literature about how such a recipe should be prepared. This article develops a protocol for preparing synthetic solutions representing the characteristics and behavior of actual PW and enabling the performance comparisons of different oil-water separation membranes at the bench scale level. In this study, two different brine recipes were prepared based on salts present in actual PW, crude oil was used as the hydrocarbon source, and a surfactant was added to disperse the oil into the aqueous phase. The recipe is accessible to the wider scientific community and was proven to be reproduceable, homogenous, stable, and comparable to actual PW field samples through analytical monitoring measurements and bench scale evaluations.
