Though touted as the best oil find of the last five years, Guando is producing only 1,700 b/d. Guando-1, Guando-2, and Guando-6 contain less oil than expected, while Guando-4 was a dry hole. Fields 3, 5, and 7 are still being explored. The Petrobras investment is part of the company's four-year plan to invest $5.2 billion overseas.
