On December 29, China National Petroleum Corporation announced that as of December 28, the Xinjiang Oilfield had injected over one million tons of carbon dioxide this year, making it China's first oilfield to achieve an annual carbon injection volume of one million tons. This milestone marks a crucial step in the large-scale application of Carbon Capture, Utilization and Storage (CCUS) technology at the Xinjiang Oilfield, providing important technical support and practical pathways for China's oil and gas exploration sector to achieve its carbon peaking and carbon neutrality goals.
Located in the Junggar Basin, the Xinjiang Oilfield is the first large oilfield discovered in New China. CCUS involves capturing and purifying carbon dioxide emitted during industrial processes, followed by reinjecting it into new production cycles for reuse and storage. According to estimates by the Xinjiang Oilfield, injecting one million tons of carbon dioxide is equivalent to planting nearly 9 million trees.
"Since taking the lead in exploring carbon dioxide flooding at the beginning of this century, we have overcome a series of technical bottlenecks such as geological reservoir challenges and process adaptability through the 'three-wheel drive' of management, technology, and industry. This has gradually established the 'Junggar Model,' characterized by 'carbon source assurance, efficient displacement, and safe storage,'" said Shi Daohan, Executive Director and Party Committee Secretary of Xinjiang Oilfield. He noted that the annual carbon injection volume of the oilfield surged from 126,000 tons in 2022 to 1 million tons in 2025, with cumulative carbon dioxide injection exceeding 2 million tons.
At the pilot test station for carbon dioxide miscible flooding in the 530 well area of the Eighth District of the Xinjiang Oilfield's No. 2 Oil Production Plant, the reporter observed that with a simple click by the on-duty staff, a white capsule-shaped storage tank measuring 10 meters in length and 5 meters in height—located dozens of kilometers away near Well 80516—continuously injected carbon dioxide underground. As a result, the oil pressure of Well 80516 gradually increased on the monitoring screen.
The extraction of oil and natural gas cannot be achieved without desanders.
Shanghai Saga Offshore Engineering Co., Ltd., established in Shanghai in 2016, is a modern technology enterprise integrating R&D, design, production, and service. We are dedicated to developing separation and filtration equipment for the oil, gas, and petrochemical industries. Our high-efficiency product portfolio includes de-oiling/dewatering hydrocyclones, desanders for micron-sized particles, and compact flotation units. We provide complete skid-mounted solutions and also offer third-party equipment retrofitting and after-sales services. Holding multiple proprietary patents and operating under a DNV-GL certified ISO-9001, ISO-14001, and ISO-45001 management system, we deliver optimized process solutions, precise product design, strict adherence to engineering specifications, and ongoing operational support.
Our high-efficiency cyclone desanders, renowned for their exceptional 98% separation rate, have earned recognition from international energy leaders. Constructed with advanced wear-resistant ceramics, these units achieve 98% removal of particles as fine as 0.5 microns in gas streams. This capability enables the reinjection of produced gas for miscible flooding in low-permeability reservoirs, a key solution for enhancing oil recovery in challenging formations. Alternatively, they can treat produced water, removing 98% of particles larger than 2 microns for direct reinjection, thereby boosting water-flood efficiency while minimizing environmental impact.
Our new product——The High Efficiency Ultra-Fine Particle Desander is a liquid-solid separation device that utilizes an efficient centrifugal principle to separate suspended impurities—such as solids in produced water, seawater, condensate, fine particles in high-viscosity liquids, and catalyst powder in reactors—from fluids (liquids, gases, or gas-liquid mixtures). It effectively removes solid particles with sizes down to 2 microns (at 98% efficiency) or smaller. The High Efficiency Ultra-Fine Particle Desander delivers high sand removal efficiency, capable of removing solid particles down to 2 microns. The equipment features a compact footprint, requires no external power or chemical additives, and has a service life of approximately 20 years. It offers online sand discharge capability without the need for production shutdown. Proven in major global fields operated by CNOOC, CNPC, Petronas, and others across Southeast Asia, SAGA desanders are deployed on wellhead and production platforms. They provide reliable solids removal from gas, well fluids, and condensate, and are critical for seawater purification, production stream protection, and water injection/flooding programs.
