Interests: Shell 50% (Shell operated), ONGC 27%, Qatar Petroleum International 23%

Fields: Ostra, Abalone, Argonauta

FPSO design capacity: 100 kb/d and 50 mscf/d of natural gas

Key contractors: BDFT (JV between SBM/MISC), Subsea 7, FMC Technologies, V&M do Brasil, Oceaneering, Transocean/Global Santa Fe, Halliburton

Production: BC-10 has produced more than 100 million barrels of oil (milestone from March 2015)


Parque das Conchas (BC-10) is one of the major milestones in the development and commercialisation of Brazil’s deep-water oil. The project comprises of three fields which have been developed with subsea wells and manifolds. All connect to a centrally located floating production, storage and offloading (FPSO) vessel, the Espírito Santo, moored in around 1,800m of water. The development is the first of its kind based fully on subsea oil and gas separation and subsea pumping. The system uses 1,500-horsepower underwater pumps – each equivalent to a Formula One engine - to drive oil and a small quantity of gas to the surface.

Environment and society

Social and environmental responsibility is a central pillar of Shell’s operations. In Brazil, Shell was one of the main sponsors of a South Atlantic humpback whale migration monitoring project from 2003 to 2014 in collaboration with Scientific Institute Aqualie. Findings have led to a better understanding of whale behaviour and will help assess how the rising number of whales affects their migratory destinations.

In local communities, Shell has focused on entrepreneurship and income generation. In 2013 we launched a version of the global Shell LiveWIRE programme, called Shell Iniciativa Empreendedora, which supports young entrepreneurs in several cities in the Espírito Santo and Rio de Janeiro states. The initiative aims to stimulate a culture of sustainability, innovation and entrepreneurship in areas near our operations.

Shell established its Environmental Education Project (QUIPEA) to engage with 21 communities where residents, known as “quilombolas”, are descended from slaves. Representatives from Shell listen to the communities’ hopes and concerns, and take actions to address them. They aim to build community trust while limiting any negative impact of nearby operations.

Current developments

The heart of Parque das Conchas (BC-10) is the floating, production, storage and offloading vessel (FPSO) Espírito Santo, which has a processing capacity of 100,000 barrels of oil equivalent per day (boe/d). Built by SBM in Singapore, the FPSO was delivered to Brazil in late 2008 and moored in around 1,800 metres of water at the Parque das Conchas (BC-10) site in the Campos Basin.

The first phase of the project included the development of three fields connected to the FPSO via subsea wells and manifolds. The double-hulled design of the FPSO required significant power and heat delivery systems to drive the seabed lift equipment and process the heavy crudes. The development wells were drilled by Global Santa Fe’s Arctic 1 drilling rig. The fields came on stream in July 2009. This first phase involved nine producing wells and one gas injector well. By July 2013 the project had produced more than 70 million boe.

Phase 2 of the project, to tie-in the Argonauta O-North field, came on stream in October 2013. It has an estimated peak production of 35,000 boe/d.

Phase 3 came on stream in March 2016. It comprises of five producing wells in two fields (Massa and O-South), and two water injection wells in Massa. The fields are tied back to the FPSO. Daily production of the Phase 3 wells is expected to add up to 20,000 barrels of oil equivalent per day at peak annual production.
