Brazil's Brava Energia kicks off drilling of two development wells in Atlanta field

en.Wedoany.com Reported - On November 9, Brazilian oil company Brava Energia commenced drilling of two new development wells, ATL-9H and ATL-10H, in the Atlanta field in the Santos Basin, using the Lone Star semi-submersible drilling rig operated by Constellation. The two wells are part of a four-well integrated drilling program covering the Atlanta and Papa Terra fields. Brava expects to begin subsea tie-back operations for the new wells in the first quarter of 2027, with first oil targeted for the second quarter.

The rig move follows the completion of operations on two new wells in the Papa Terra field. The Lone Star previously carried out the PPT-52 and PPT-53 drilling assignments, of which PPT-52 came on stream on September 29, 2026, while PPT-53 has completed drilling, completion and tie-back to the 3R-3 floating production, storage and offloading (FPSO) vessel and is awaiting regulatory approval to start production. After completing these operations, the rig relocated to the Atlanta field to continue with the ATL-9H and ATL-10H drilling assignments.

The Atlanta field is located in the Santos Basin at a water depth of approximately 1,500 meters. Brava serves as operator with an 80% interest, while Westlawn Energia holds the remaining 20%. The field produces through the Atlanta FPSO. The two new wells will be tied back to existing offshore production facilities, with no need to build a separate standalone floating production system. Brava expects subsea tie-back of the two wells to begin in the first quarter of 2027, with first oil in the second quarter.

According to Brava's disclosed third-quarter 2026 operating data, the Atlanta field achieved average production of 31,900 barrels of oil equivalent per day during the quarter, and crude oil sales volume increased by 42% quarter-on-quarter on a 100%-interest basis. Once ATL-9H and ATL-10H come on stream, they will add new production sources to the existing facilities. The two new wells, together with PPT-52 and PPT-53 in the Papa Terra field, make up the four-well drilling program.
