RIO DE JANEIRO, Dec 22 (Reuters) - Brazil's Barra Energia SA said on Tuesday tests at the Carcará offshore oil prospect it owns with Petroleo Brasileiro SA, Galp Energia SGPS SA and QGEP Participações SA show the field has "enormous" output potential.
Tests at the site also show that pressure, while unusually high, is spread evenly throughout the reservoir and that wells at the site could produce at levels of 40,000 barrels a day or more, equal to or greater than the highest producing wells in the giant and prolific Lula and Sapinhoa fields.
Petroleo Brasileiro SA, commonly known as Petrobras, owns 66 percent of Carcará and is the site's operator. Portugal's Galp owns 14 percent and Barra Energia and Brazil's QGEP each own 10 percent. (Reporting by Jeb Blount; Editing by Paul Simao)
