Enauta producing from two Atlanta wells following repairs

Brazilian oil and gas company Enauta has resumed operations in one of the two producing wells in the Atlanta field that were shut down due to pumping system failures.

Enauta said on Tuesday that the Atlanta field, located in Block BS-4 offshore Brazil, was now producing from two of the three wells.

The Atlanta field early production system has three wells, two of which stopped production due to pumping system failures in early July. At the time, the company said that the field would be producing from the one working well while one of the wells that was shut down was expected to resume production in the second half of July.

The second well is scheduled to restart production in August 2021 and the field will be producing from three wells from then on. All three wells on the Atlanta field are producing via their connection to the Petrojarl I FPSO.

Enauta added in the statement from Tuesday that the seabed pump was activated on 18 July 2021. Production quickly returned to the level recorded before the interruption of around 17,000 to 18,000 barrels per day.

The company added that the seabed pump of the other well that had been stopped has also been enabled. As a result, the three wells are in operating condition but the resumption of production with three wells will occur following the repair of oil heaters on the platform.

To remind, Enauta completed the transfer of a 50 per cent stake in the Atlanta offshore field, previously held by Barra Energia, in late June. The approval from the country’s authorities to take over Barra Energia’s stake was received in April.

At the time of the takeover, the field was operating via two wells. Enauta announced a restart of the third as well as an increase in production from approximately 9,000 to 18,000 barrels of oil per day immediately. It hoped to achieve nearly 22,500 barrels of oil per day after the entry of the third well – an all-time high for Enauta.

The company also stated in late June that activities were underway to expand the water treatment capacity of the FPSO and increase oil production, with the first phase expected to be concluded by the end of this year. Enauta is also evaluating the possibility of anticipating the drilling of the fourth well in the field.

Earlier this year, Enauta initiated the bidding process for the FPSO for the full development system of the Atlanta field.
