The composition of produced water from natural gas wells significantly influences its treatment requirements before disposal because produced water contains a variety of contaminants that must be removed to meet environmental regulations. Produced water is water that is brought to the surface during oil and gas extraction. Its composition varies depending on the geological formation, the type of well, and the extraction methods used. Common contaminants in produced water include dissolved salts (e.g., sodium chloride, calcium chloride), oil and grease, suspended soli....
