Peru opened international bidding on seven energy blocks in the Amazon that will require a total investment of $3.15 billion, the government said on Monday.
The concessions, which include exploratory and production blocks, will be auctioned in August of next year, said state energy agency Perupetro.
More than 10 oil companies from the United States, Canada, Russia, Asia and Latin America have expressed interest, said Perupetro, without naming any of the companies.
Last week Perupetro awarded the rights to develop two oil blocks to the country's biggest construction company. It said Petroperu, the state energy firm, would take a minority stake in the concessions.
Last year Peru produced 63,000 barrels of oil per day.
