FPSO working off Brazil undergoing preventive maintenance

Brazilian oil and gas player Enauta has revealed that a floating, production, storage and offloading (FPSO) vessel, which is carrying out operations on a field offshore Brazil, has embarked on preventive maintenance activities.

Enauta disclosed on Wednesday, 22 February 2023, that the water-cooling system of the FPSO Petrojarl I had entered preventive maintenance and the maintenance interruption should last until the beginning of the next week. The Brazilian player explains that this type of activity is part of the operational routine of floating production units, which normally operate with an efficiency – operation rate or uptime – close to 90 per cent.

According to Enauta, the FPSO Petrojarl I has been producing with an excellent uptime of 98 per cent in the last three months, after its recertification. Moreover, the FPSO presented an operation rate of 92 per cent throughout 2022. The firm says that this maintenance is included in the FPSO operation plan, thus it is not affecting production estimates.

At the end of 2022, Enauta kicked off the three-well drilling campaign at the Atlanta field. The first well, which is in the connection phase to the FPSO Petrojarl I, should start production in April 2023, when the FPSO will have three wells online, which is its maximum capacity.

With the entry of this new well, the Atlanta field’s potential production will be increased to more than 20,000 barrels of oil per day. In addition, Enauta claims that it will have operational redundancy in the pumping system, leading to “a greater production stability.”

Enauta bought the FPSO OSX-2 for Atlanta’s Full Development System (FDS) last year, which is expected by mid-2024, originally with six wells, reaching ten wells in 2029. This FPSO, known as the FPSO Atlanta is anticipated to be fully operational by 2024.

With estimated reserves of 106 MMbbl, the Atlanta field is located in block BS-4 in the Santos Basin, at a 1,500-metre water depth. It is operated by Enauta Energia, a wholly-owned subsidiary of the company, which also has a 100 per cent interest in this asset.
