Technology

Parque das Conchas (BC-10) represents a key milestone in the development and commercialisation of Brazil’s deep-water oil. The three fields have been developed with subsea wells and manifolds, with each field tied back to a centrally located Floating Production Storage and Offloading (FPSO) vessel moored in around 1,780m of water. The development is the first of its kind based fully on subsea oil and gas separation and subsea pumping. The drilling programme uses floating-rig surface blow-out preventer well drilling and completions.

The development includes the first application of steel tube hydraulic and multi-circuit high power umbilicals, which deliver power to 1,500-horsepower pumps on the sea floor. It is also the first application of lazy wave steel riser technology on a turreted FPSO.

Environment and society

Social and environmental responsibility is a central pillar of Shell operations. In Brazil, Shell has been the sole sponsor of a humpback whales migration project, in collaboration with Scientific Institute Aqualie, in the South Atlantic Ocean since 2002. Findings have led to a better understanding of the whales’ behaviour and will help assess how the rising number of whales affects their migratory destinations. In the medium term, the studies will help guide the oil industry to make responsible operational decisions that factor in sustainability.

At a more local level, Shell has focused on entrepreneurship and income generation. In 2013 it launched a version of the global programme, Shell LiveWIRE, which supports young entrepreneurs. Called Shell Iniciativa Empreededora, this initiative aims to stimulate a culture of sustainability, innovation and entrepreneurship in areas near to our operations.

Shell Environmental Education Project (PEA) is designed to engage with 20 communities descended from slaves, known as “quilombolas”. Representatives from Shell are listening to the communities’ hopes and concerns, and taking action 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) Espἰrito Santo with 100,000 boe/day processing capacity. Built by SBM in Singapore, the FPSO was delivered to Brazil in late 2008 and moored in around 1,780 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 tied back to the FPSO, via subsea wells and manifolds. The double-hulled FPSO’s design required significant power and heat delivery systems needed to drive the seabed lift equipment and process the heavy crudes. The development wells were drilled by Global Santa Fe’s Arctic 1. 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 with a peak production of 35,000 boe per day.

In July 2013 Shell and its partners Petrobras and ONGC announced that they would move forward with Phase 3 of the project, which will include the installation of subsea-infrastructure at the Massa and Argonauta O-South fields. These fields will be tied-back to the Espírito Santo. Once online, Phase 3 of the BC-10 project is expected to have a peak production of 28,000 barrels of oil equivalent (boe) per day.
