Petrobras strikes again in pre-salt

Brazil's state-run oil company Petrobras struck light oil with an ultra-deep water well in the offshore Santos basin.

It provided no reserve estimates. Portuguese company Galp Energia is Petrobras' partner in Block BM-S-21 with a 20% stake. The 1-BRSA-526-SPS (1-SPS-51) well was drilled in water 2234 metres deep found light oil in the pre-salt layer, said Petrobras. The well was not tested due to operational and logistics matters. Last month, Petrobras announced an estimate for recoverable reserves at its giant Tupi field in the sub-salt cluster of the Santos basin of between 5 billion and 8 billion barrels. If confirmed, that would make Tupi the world's second-largest oil find in the past 20 years after Kashagan in Kazakhstan.
