Shell produces first oil from phase 2 of Parque das Conchas, ultra-deepwater Brazil; deepest seismic monitoring system
2 October 2013
Shell and its partners have begun production from the second development phase of the Parque das Conchas (BC-10) project, located in ultra-deep waters off Brazil’s south-east coast. The BC-10 project (Shell share 50%, Petrobras 35%, ONGC 15%) comprises several subsea fields which are tied back to a floating production, storage and offloading (FPSO) vessel, named the Espírito Santo.
In 2009 the first phase of the project began production, when the Abalone and Ostra fields were connected, along with the Argonauta B-West reservoir. The peak production of the first phase was more than 90,000 barrels of oil equivalent (boe) in 2010, and is currently producing some 35,000 boe per day. Phase 2 connected a fourth reservoir to the vessel, the Argonauta O-North. At its peak, Phase 2 is expected to produce approximately 35,000 boe per day.
A 4-D Life of Field Seismic monitoring system was installed as part of Phase 2 subsea development. This technology, consisting of a network of seismic sensors installed throughout the field on the seabed, allows Shell more effectively and efficiently to monitor the reservoir. This is the deepest installation of its kind on a full-field scale in the world (approximately 1800m or 5,900 feet).
Expecting to maximize the production life of BC-10 even further, Shell and its partners recently announced in July the decision to move forward with the project’s third development phase, which will include the installation of subsea-infrastructure at the Massa and Argonauta O-South reservoirs. Once online, Phase 3 of the BC-10 project is expected to reach a peak production of 28,000 boe.
