Enauta temporarily interrupted the production at the Atlanta field on Tuesday, 25 April 2023. Based on the firm’s technical area, preliminary assessments indicated failure of subsea equipment associated with the 7-ATL-2HP-RJS well while the other two wells were expected to return to production later that day. In an update on Wednesday, 26 April 2023, the Brazilian player confirmed the production from the 7-ATL-4H-RJS and 7-ATL-5H-RJS wells was resumed, as expected. 

However, the 7-ATL-2HP-RJS well remains inoperative and needs to have its pump replaced by a reserve pump. Enauta says that the return to production is scheduled for the month of June, after the planned shutdown. Currently, the production at the Atlanta field is approximately 12 thousand bbl/d and is still ramping up.

Located in block BS-4 in the Santos Basin, at a 1,500-metre water depth, the Atlanta field has been producing since 2018 through an Early Production System (EPS), which entails three wells connected to the FPSO Petrojarl I. The field is operated by Enauta Energia, a wholly-owned subsidiary of the company, which has a 100 per cent interest in this asset. The field’s reserves are estimated at 106 MMbbl.

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