The well is producing at rates of 12,000 to 14,000 bbl/d via a subsea flowline and umbilical connected to the Cidade de Itajaí FPSO.
Operations at the second producer, PAT-1, should begin by the end of March. Following an initial few days of flush production, output from the two wells should then stabilize at 10,000 to 15,000 bbl/d, lifting total output from the BM-S-40 license above 30,000 bbl/d.
At some point, depending on the reservoir and aquifer response, one of the two wells could be switched to water injection. Any gas produced from Patola will be reinjected into the Baúna reservoir through the SPS-89 gas injection well.
Petrobras discovered the Patola Field in 2011 in 280 m of water in the same Oligocene turbidite sandstones as in the nearby Baúna and Piracaba fields, with similar petrophysical properties. Karoon committed to the development last June after acquiring the license from Petrobras.
Altera and Ocyan operate the FPSO. The Noble Developer has drilled the wells while TechnipFMC designed, fabricated and installed the Patola subsea infrastructure under an integrated engineering, procurement, construction and installation contract.
Last week Karoon’s Neon-2 (9-NEO-2D-SPS) control well reached a final total depth of 2,357 m with the lower section deviated to the west to intersect target zones 1.3 km north of the Echidna-1 discovery well. Wireline logging of the target sections continues.
