China’s natural gas sector is grappling with a pressing issue: the treatment and disposal of produced water from gas fields. A recent study published in ‘Gongye shui chuli’ (Industrial Water Treatment) sheds light on this critical challenge, revealing that the efficient management of produced water is vital for ensuring the stability of natural gas production and, by extension, national energy security.
Lead author Yang Shugang from the CNPC Research Institute of Safety and Environment Technology Co., Ltd. emphasizes the urgency of addressing this issue. “The simultaneous production of gas and water in major gas fields, particularly in the Ordos, Tarim, Sichuan, and Qaidam basins, has resulted in a sharp increase in water production,” Yang explains. This situation poses significant operational challenges and raises costs for energy companies striving to meet environmental regulations.
The study identifies several key challenges that the industry must overcome. Among these are the increasing volumes of produced water, the absence of a national reinjection management system, and the high costs associated with meeting surface discharge standards. “Without a cohesive framework for managing produced water, companies face not only financial burdens but also risks to groundwater environmental protection,” Yang warns.
In response to these challenges, the research advocates for a multi-faceted approach. Strengthening national standards for reinjection and promoting the comprehensive resource utilization of produced water are crucial steps. Yang suggests that these measures could lead to innovative solutions that not only address environmental concerns but also enhance the overall efficiency of gas production.
The implications of this research extend beyond environmental protection; they have significant commercial ramifications for the energy sector. As companies adapt to the strategic goals of “stabilizing oil and increasing gas” and achieving “double carbon” targets, effective produced water management could become a competitive advantage. Yang notes, “By promoting reinjection and surface discharge tailored to local conditions, we can support the energy sector’s growth while safeguarding our natural resources.”
As the energy landscape continues to evolve, this research underscores the importance of integrating environmental stewardship with operational efficiency. The findings may pave the way for future developments in produced water management, ultimately contributing to a more sustainable energy future in China.
