World Oil & Gas News

LISBON, Portugal — Galp Energia says a second well on the Carcará discovery in the presalt Santos basin offshore Brazil has encountered light oil.

Well 3-SPS-105, informally known as Carcará North, was drilled 4.6 km (2.9 mi) north of the discovery well in block BM-S-8 in 2,072 m of water, around 229 km offshore the S?o Paulo state coast.

To date, the well has intersected a 358-m (1,174-ft) column of 31°API oil in good-quality, interconnected carbonate reservoirs below the salt layer at a depth of 5,820 m (19,094 ft). Pressure data have confirmed that it is the same accumulation as of the discovery well.

Galp has a 14% stake in the concession via its subsidiary Petrogal Brasil. The other partners are Barra Energia do Brasil Petróleo e Gás and Queiroz Galv?o Explora??o e Produ??o.
