About Round 8

The Brazilian National hydrocarbons regulator ANP has awarded 38 explorations blocks offered in the Round 8 Hydrocarbon licensing round known as Round 8. However, a federal judge in Brasilia on the afternoon of November 28, 2006 issued an injunction suspending the auction after a congresswoman of the governing Workers Party had challenged a rule of the auction that limits the number of bids each company is allowed to place at the auction.

The ANP issued a statement on November 29, 2006 saying that it was not successful in overturning the suspension of the Round 8 auction and, as a result, has declared the auction ended. The ANP still expects to overturn the injunction.

"We regret this. We think the (judicial) process is incorrect", ANP President Haroldo Lima said. "We know some companies have prepared themselves months for this." At this time it is unclear whether the awarded licenses will continue to be valid after the suspension of the auction. During previous Round, Brazil's oil block auctions have been challenged in the courts, with ANP successfully overturning any judicial actions against them.
