On January 3, the Búzios VI project in Brazil, in which China National Offshore Oil Corporation (CNOOC) holds an interest and participates as a partner, has successfully commenced production. Located in the Santos Basin off the southeastern coast of Brazil, the project operates at a water depth of 1,900 to 2,200 meters and is developed using a floating production, storage, and offloading (FPSO) unit.
The newly operational Phase VI project has a designed daily production capacity of approximately 25,000 tons of crude oil and natural gas processing capacity of 7.2 million cubic meters per day. As a crucial component in maintaining production continuity at the Búzios field, this project will help increase the field’s total output to over 1.15 million barrels per day. Luiz Schmall, General Manager of Petrobras’ Búzios Field, stated, “The FPSO P-78 of the Búzios Phase VI project is the first self-built FPSO at the Buzios field following CNOOC’s participation in the acquisition. Multiple modules, including the topside oil, gas, and water processing units, were constructed at domestic shipyards.”
CNOOC currently holds a 7.34% stake in this integrated development project. In addition to this project, CNOOC also holds interests in other deepwater oil and gas assets in Brazil, such as the Mero field. Recently, the China-Brazil Science and Technology Innovation Center, jointly established by the two parties, has commenced physical operations. The center aims to build a collaborative ecosystem integrating “industry, academia, research, and application” by leveraging industrial practices and scientific research capabilities.
The extraction of oil and natural gas cannot be achieved without desanders.
Shanghai Shangjiang Petroleum Engineering Equipment 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, SJPEE 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, SJPEE 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), and multi-chamber hydrocyclones, delivering comprehensive solutions for the industry’s toughest challenges.
