Brazil has more than 60 platforms with more than 25 years


According to the ANP, age represents a considerable criterion for decommissioning


About 40% of the 158 offshore production platforms in Brazil are over 25 years old – a considerable criterion for decommissioning, according to the ANP. The numbers were presented by the agency’s Superintendent of Operational Safety, Marcelo Mafra, during Rio Oil and Gas 2018.

Most of these units are concentrated in shallow and intermediate waters of basins such as Campos, Ceará and Sergipe-Alagoas. The most common type are jack-ups.

Among the decommissioning projects currently under analysis by the ANP are the P-7, P-12, P-15, P-33 and FPSOs Rio de Janeiro and Piranema platforms. In the list of already approved are FPSO Brazil, Marlim Sul and Cação.

The ANP plans to launch this year the draft resolution that will regulate decommissioning activities. Among the proposals is the requirement to present the plan between three and five years before the execution of the project to the ANP to ensure predictability.

According to Mafra, the total removal of the platform and underwater structures will be the standard condition, but partial removal or non-removal will be accepted if duly justified.

The idea is to have a decommissioning plan approved by the three competent authorities (ANP, Ibama and Navy) in order to rationalize the process.

Decommissioning vs. recovery factor increase

The ANP superintendent said that the focus of the agency is the increase of the recovery factor of the oil fields. The Campos Basin, for example, has an index of only 14%, while the Brazilian average – considered low – is 21%.

“For every 1% increase in the recovery factor adds 1 billion barrels of recoverable oil,” Mafra said.

A Wood Mackenzie study estimates that decommissioning costs in the Campos Basin by 2025, including 32 platforms, amount to $ 8 billion.

“If this amount were invested in revitalization plans, it would be possible to add 230,000 bpd to production in the region, generating $ 3 billion in royalties and 30,000 jobs per year in the period,” estimates Luiz Hayum, the researcher.
