Oil and gas major Royal Dutch Shell and its partners have commenced production from the second development phase of the Parque das Conchas (BC-10) project.
Located off Brazil’s south-east coast, the BC-10 project comprises of several subsea fields which are tied back to a floating production, storage and offloading (FPSO) vessel, Espírito Santo.
Phase one of the project began production in 2009, when the Abalone and Ostra fields were connected, along with the Argonauta B-West reservoir, and it produced more than 90,000 barrels of oil equivalent (boe) in 2010 at its peak.
At present, it is producing some 35,000boe per day.
Phase two, which connected a fourth reservoir to the vessel, the Argonauta O-North, is expected to produce about 35,000boe per day at its peak.
Shell Upstream Americas deep water executive vice president John Hollowell said: "Boosting production at BC-10 with the completion of phase two is another great example of our successful project development, delivery and execution capabilities."
As part of phase two subsea development, a 4-D Life of Field Seismic monitoring system was installed.
Integrating a network of seismic sensors installed throughout the field on the seabed, the technology, installed at about 1,800m (or 6,000ft), allowed the company to monitor the reservoir.
In July, Shell and its partners decided to move forward with phase three of the project to maximise the production life of BC-10 even further.
The development will include the installation of subsea-infrastructure at the Massa and Argonauta O-South reservoirs.
Phase three of the BC-10 project, once online, is expected to reach a peak production of 28,000boe, the company said.
Shell operates BC-10 project with a 50% share and partners, Petrobras and Oil & Natural Gas Corporation (ONGC), own 35% and 15% respectively.
