Brazil's state-run Petroleo Brasileiro SA found new deposits of light oil in deep waters off the coast of the northern state of Sergipe.
Petrobras is operator of the field with 75 per cent stake. India's state-run Oil and Natural Gas Corp is partner with 25 per cent stake.
"The reservoirs contain light oil of good market value and are 85 metres wide, with good porous and permeable conditions," Petrobras said. It said another test is needed to confirm the conditions and establish the well's potential.
Well 3-SES-189, located in the Poço Verde area discovered in 2012 in the BM-SEAL-4 exploration block, was drilled down to 5,350 metres in waters 2,479 metres deep, the company said.
