Abstract

Historically, due to variations in reservoir geological conditions, production technologies, and the duration of extraction across different oil and gas fields, the produced water exhibits a highly complex composition, significant quality fluctuations, and severe emulsification. Furthermore, as the water cut in mature oilfields worldwide continues to rise, the rate of produced water reinjection has failed to keep pace. Consequently, the volume of oily produced water requiring discharge from these mature fields is increasing steadily. In this context, ensuring that the treated effluent meets regulatory discharge standards has emerged as a critical challenge for wastewater treatment projects in such oilfields. Currently, the application of high-efficiency reverse demulsifiers represents a highly effective approach to address the challenge of destabilizing these difficult-to-treat produced water emulsions.
