BW Energy to invest US $ 250 million in Maromba

May 30, 2019

BW Energy will invest US $ 250 million in the first phase of development of the Maromba field in the Campos Basin, the company said in its first presentation to the market.

The start of implementation of the project – which will have four phases of development – is planned for the second half of 2020, and the first oil for the second half of 2022.

The first phase involves the drilling of two to three wells, which will be interconnected to the BPS Offshore FPSO Berge Helene, which is in the docking process. The production estimate for Phase 1 is 20,000 bopd of heavy oil, of 16º API.

The second phase includes the drilling of six more wells in the field, four producers and two injectors, and the hiring of another platform. At this stage, production should be increased to 35 thousand bopd.

In the last and third phase, the focus will be the development of the reservoirs of the Maastrichtian and Eocene periods. According to the company, tests by previous operators have confirmed that the chances of production success are high.

BW Energy’s estimate is that during its third phase of development the Maromba field will be producing 40,000 bopd.

As Maromba is close to the Peregrino, Polvo and Papa Terra fields, where BW Offshore has FPSOS in operation, the company intends to replicate solutions.

The ANP also has to approve the transfer of BW Offshore’s stake in Maromba (100%) to BW Energy, which is no longer subsidiary but an independent company. The operation is expected to be formalized by the regulatory agency in the third quarter of this year.

Historical

The BC-20A concession, where Maromba is located, was acquired by Petrobras (operator) and Chevron in ANP’s Round Zero in 1998, with interests of 62.5% and 37.5%, respectively. In 2012, the US oil company sold a 7.5% stake to Petrobras, which now holds 70% of the project.

The field was discovered in 2003 with the drilling of well 1-BRSA-216-RJS (1-RJS-609) in depth of 161 m. In all, nine wells were drilled in the block, eight oil producers and one gas injector. The declaration of commerciality of the field was made in 2006.

Originally, Petrobras’ plan was for Maromba to start operating in 2010 through a pilot production system, which would consist of two wells interconnected to the FPSO Cidade de Rio das Ostras.

For the definitive system, different options were evaluated, one of them contemplating the use of a fixed platform in conjunction with an FPSO. After technical studies, however, Petrobras concluded that the fixed unit would not be necessary.

In total, 97 km of flexible pipelines would have been launched interconnecting nine wells (eight producers and one injector) to the platform, whose capacity would be 100 thousand bopd.

The idea was to separate the oil from the gas, treat it, store it in the tanks of the unit, and send it ashore via relief ships. The gas produced would be used as fuel in the generation of energy for the platform itself and the surplus, injected for storage.

In 2013, Petrobras decided to reduce the FPSO’s production capacity to 60,000 bopd and postpone the first oil field from 2015 to 2017.

Three years later – in the face of the inertia of the project – the ANP threatened to tender the Maromba field again, along with 26 other inactive concessions, which did not happen because the asset was included in Petrobras’ divestment program.
