Brazil's Búzios oil field has reached a daily output of 1.2 million barrels, hitting a record high!

Recently, the Búzios field in Brazil—the world’s largest deepwater pre-salt oil field, in which CNOOC has participated and holds equity—has delivered good news. Petrobras announced that the Búzios field has reached a daily output of 1.2 million barrels, setting a new historical high. The continued production increase of this world-class pre-salt field not only validates the enormous potential of its ultra-deepwater carbonate reservoirs, but also imposes higher demands on operational efficiency, safety, and intelligence.

In response to this challenge, CNOOC, together with the Brazilian innovation center CESAR and the Federal University of Alagoas (UFAL), has officially launched a digital twin project focused on optimizing drilling and completion operations at the Búzios field. According to BNAmericas, this project is part of the mandatory R&D investments required by Petrobras and the National Agency of Petroleum, Natural Gas and Biofuels (ANP). With a duration of 36 months, the funding allocated to CESAR alone amounts to 18.5 million reais (approximately US$3.61 million).

Tiago Bockholt, business manager at CESAR, stated that the project aims to develop artificial intelligence models to support wellhead operations, by structuring large volumes of operational data to provide technical teams with predictive analyses and recommendations. At the project's launch, the field's output had just surpassed 1.1 million barrels, and it has now jumped to 1.2 million—making its forward looking nature and urgency self evident.

At this juncture of record breaking production, this seemingly modest technical investment actually reflects CNOOC's deeper transformation in its deepwater strategy in Brazil and globally—shifting from passively following operators to proactively building core technological capabilities in pre salt ultra deepwater, and laying a solid digital foundation for future independent operations.

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.
