New campaign will include a well for the early production system


Enauta will charter a rig for the Atlanta field, in the Santos Basin, which is expected to start operating in 2022. The oil company will launch in early September a tender to hire a unit for 1.5 thousand meters of water depth to drill the fourth well of the early production system, continuing the market consultation started about a month ago.


The information about the new contracting process was confirmed by Carlos Mastrangelo, Enauta’s Chief Operations Officer. The companies will have to submit proposals at the beginning of October.


The oil company’s drilling campaign will begin in the third quarter of 2022. Enauta’s goal is to connect the new well to the Petrojarl I FPSO in the last quarter of next year.


The activity is expected to take about 55 days. Since the campaign is small, it is most likely that the winning company will offer an available unit in Brazil.


The drilling of the fourth well of Atlanta’s early production system aims to increase total oil production with lower water production. The new well will replace one of the producing wells in operation today in the field.


Currently, the Atlanta early system operates with three wells. Enauta has not yet defined which well will be replaced. The technical team has been examining the best solution for the project, and the hammer will only be struck in mid-2022, before the drilling campaign begins.


The current water processing capacity of the Petrojarl I FPSO is 5,900 barrels per day. The plant will be expanded to 8,000 barrels/day by the end of this year and 20,000 in 2022.


So far, Enauta has no firm date for hiring the rig that will be responsible for the drilling campaign of the wells of the definitive Atlanta system, scheduled to start operating in mid-2024.


Atlanta’s definitive production system will have between six and eight wells, part of which will be relocated from the current project. Enauta recently pre-qualified Yinson as a preferred bider for the conversion process of the OSX-2 FPSO, which will be used on the project.


The FPSO company will submit a firm commercial and technical proposal for the project in October. The FPSO is capable of producing 100,000 barrels of oil per day, but it will have to be adapted to 50,000 barrels per day for heavier 14º API oil.


Yinson is working with three different shipyard scenarios for the OSX-2, all located abroad. The contract for the definitive Atlanta FPSO will have a charter term of 15 years, with the possibility of extension for longer depending on the production results.
