Petrobras discovers oil and gas in Amazon and Espírito Santos basins

Petróleo Brasileiro SA (Petrobras) has confirmed the discoveries of oil and gas accumulations in Brazil’s Amazon and Espírito Santos basins.

The company’s discovery in the Amazon Basin was made in Block AM-T-84 while drilling well 1-BRSA-1293-AM (ANP nomenclature), informally known as Jusante do Aneba. Well drilling reached the total depth of 6,693 feet (2,040 meters). Preliminary well tests have confirmed the presence of light oil (API 47 degree) and gas in arenaceous reservoirs, extending from 4,429 feet (1,350 meters) to 6,233 feet (1,900 meters) deep.

Petrobras is the operator of the concession (60%), in partnership with Petrogal Brasil (40%). The consortium will evaluate these reservoirs through a cased-hole drillstem test.

Separately, Petrobras also announced the discovery of an onshore oil accumulation in the Espírito Santo Basin. The discovery was made by drilling wildcat well 1-BRSA-1302-ES (ANP nomenclature), informally known as Guayacan. This well comprises the discovery evaluation plan of Tabebuia and is located 74.5 miles (120 kilometers) from the city of Vitoria. Reservoirs are located at 2,333 feet (711 meters) deep, and well drilling reached 4,304 feet (1,312 meters).

Petrobras is the operator and detains 100% of exploratory block ES-T-495. The discovery will be evaluated by formation tests, as part of the evaluation plan’s exploratory program.
