The Albacora-Leste Oil Field is an oil field located in Campos Basin. It was discovered in 1986 and developed by Petrobras. The oil field is operated by Petrobras, that owns 90% of the field, while Repsol owns the remaining 10%.[1] The total proven reserves of the Albacora-Leste oil field are around 534 million barrels (72×106tonnes), and production is centered on 180,000 barrels per day (29,000 m3/d).[2] In April 2022, Petro Rio (through its subsidiary Petro Rio Jaguar Petróleo), acquired a 90% operating stake in the Albacora Leste field Petróleo Brasileiro (Petrobras) for $2.2bn USD.[3]

Geology
The Albacora field consists of several producing horizons of Albian to Miocene sandstone turbidites, with an area of 235 km2.[4]: 124 Reflection seismology in 1972 disclosed a faulted anticline and seismic amplitude bright spot, which was drilled by wildcat 1-RJS-297 in 1984 and discovered oil.[4]: 126 The stratigraphy of the Campos Basin starts with the Lower Cretaceous Lago Feia Formation a source rock, followed by the Albian Macae Formation consisting of shallow water carbonates overlain by late Albian shales, marls, calcilutites, and turbidite sandstones.[4]: 128 From this formation through most of the Cenozoic, the Campos Formation was deposited, consisting of deep water turbiditic sandstones and shales, the main producers in the Albacora and Marlim fields.[4]: 129 Finally, the basin was filled by the Ubatuba Formation, consisting of slope and shelf deposits.[4]: 129
