2019 will bring the revitalization plan for the Marlim and Voador fields, Petrobrás projects involving the retirement of nine FPSOs and the installation of two new units. But deadlines are short to maintain the schedule of the new platforms in 2021, as predicted in the company’s business plan.
FPSOs 1 and 2 are units with daily processing capacity of 70 thousand and 80 thousand, much lower than other units that Petrobrás contracts for the pre-salt, but with a great demand for water injection that increases the complexity of the projects. It is estimated that a peak of 100,000 barrels / day of oil will be reached, with an injection of 440,000 barrels / day of water, in addition to the production of 2.35 million m3 / day of natural gas.
The projection of reaching 100,000 barrels per day at the peak of the revitalization project may imply a reduction from the current level of Marlim and Voador, which produced 133,000 barrels a day and 2,000 barrels a day, respectively. On the other hand, revitalization will make it possible to scale the production system to the current capacity of the reservoirs, extending the useful life of the assets and increasing the total recovery of oil and natural gas.
The deadline for this is still undefined and can be from 3 years to 3.5 years, between the hiring and the entry into operation of the new platforms. This, in a way, puts pressure on the installation schedule of the two units by 2021. A consultancy is planned to manage the implementation of the plan to deactivate the nine FPSOs in the Marlim field. The schedule foresees that work begin in December this year, lasting until 2023. The decommissioning of the Marlin platforms was scheduled to begin in 2016 and has already been postponed for this year. The P-18, P-19, P-20, P-26, P-32, P-33, P-35, P-37, and P-47 platforms need to be decommissioned.
In addition to the decommissioning services for the units, there will be an intensive demand for services in almost 90 wells that will be relocated from the current platforms and another ten new wells that will be drilled. The project will also drive the subsea lines and equipment market.
The Marlim Field was discovered in January 1985, through well RJS219A. It is located in the Campos Basin, about 110 km from the coast of Rio de Janeiro. Due to the size and complexity of the project, the development of this field was planned in 5 modules with seven production units (four SS-type “semi-submersible” and 3 FPSO type) and 1 treatment and storage unit. The collection of the oil from the wells to the production units is done through flexible lines / risers and manifolds.
The National Petroleum Agency (ANP) and Petrobras signed a two-year extension of the Marlim and Voador contracts until 2052. With a combined capacity of 835 thousand barrels / day of oil processing and compression of 16.9 million m³ / day of natural gas, the fields of Marlim and Voador will begin to produce with a leaner system, 150 thousand m³ / day and 11 million m³ / day respectively, distributed in the two FPSOs.
