The total crude oil production of the Bayan Oilfield in Inner Mongolia, China, has surpassed 6 million tons
The cumulative crude oil production of the Bayan Oilfield in Bayan Nur, Inner Mongolia, has exceeded the 6 million ton mark. This comes just seven months after it surpassed 5 million tons in December 2025, marking another million ton milestone.
In the first half of the year, the oilfield produced over 870,000 tons of crude oil, completing 51% of its annual target. Its daily output remained stable at 4,800 tons, up 20% year on year, contributing nearly one third of the daily production of the Huabei Oilfield.
Currently, the Hetao Basin, where the Bayan Oilfield is located, is still in the early stages of exploration and development. Proven reserves account for only a portion of the estimated resources, leaving considerable room for further reserve growth and production increases. According to the plan of Huabei Oilfield, the Bayan Oilfield will continue to promote integrated exploration and development, accelerate the construction of production capacity in new blocks, and strive to build a million-ton crude oil production base during the 15th Five-Year Plan period (2026–2030). As an important replacement area for Huabei Oilfield’s crude oil production growth, the sustained development of the Bayan Oilfield is of positive significance for ensuring regional energy supply.
The extraction of oil and natural gas cannot be achieved without separation equipment.
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.
Beyond desanders, SAGA offers a portfolio of acclaimed separation technologies. Our product line includes membrane systems for natural gas CO₂ removal, deoiling hydrocyclones, high-performance compact flotation units (CFUs), Shale gas desanding, Cyclonic dewatering package with produced water treatment, and multi-chamber hydrocyclones, delivering comprehensive solutions for the industry's toughest challenges.
