This work aims to refresh the information about the geology of the Barreirinha's Basin with the intention to determine the conditions for the occurrence of oil and natural gas as well as analyse the remaining questions in regard of the delimitation of the basin's boundaries and how those interfere with the auction process promoted by the Petroleum Nacional Agency (ANP) and the exploration and production activity. Barreirinha is a marine ambience basin located at the brazilian equatorial margin limited to the east by the Tutóia High, to the west by the Ilha de Santana Platform and to the south by the Sobradinho Platform. To the northwest it is separated from the Pará-Maranhão Basin by the meridian 44º without any geological justification. The two basins resemble each other in lithological content; Lithostratigraphic piling; biostratigraphic piling, and the structural features on the frontier between the two are mixed because the trend of the faults have the same direction NW-SE. The genetic connection between the basins explains the similarities, but it doesn't solve the problem created on the ANP's new areas bidding process in the event of the discovery of a commercial reservoir in one of the two basins. Despite the problematic presented, the interest in the exploitation of Barreirinha's Basin was shown high as the 11ª round of ANP's auctions revealed itself a success with 26 blocs offered from which 19 were acquired adding to the 06 blocs acquired on previous rounds. The possibility of hidrocarbonate production in the basin is relevant for Pará's energetic market considering the proximity and the availability of the utilization of natural gas in the complementary energy generation industry between other uses. |
