Decommissioning and abandonment of Brazilian offshore oil and gas fields has become more important in the last few years because of the maturing hydrocarbon-producing basins in the region. However, a complete abandonment of a Brazilian offshore field has not been completed to date and the consequent lack of a reference case leads to uncertainties with operators and stakeholders during the conceptual phases of abandonment. This paper aims to develop a Brazilian baseline for front-end planning and cost estimation of the decommissioning, removal, and disposal options.
Brazilian Decommissioning Context
Decommissioning and abandonment of offshore facilities and infrastructure in Brazil is relatively immature compared with other more-mature global oil and gas operating regions. To date, only six fixed platforms and five floating production units have been decommissioned in Brazil.
