Exploration History

History

Petroleum exploration in the Amazonas Basin started in 19171917. It was carried out by the Brazilian Geological and Mineralogical Service (SGMB) - in this time the focus was coal exploration.

In 19251925, the first oil and gas shows occurred near the Itaituba city. In 19531953,, Petrobras was created.

The exploratoy efforts in Amazonas Basin can be divided into three phases:

53 stratigraphic wells and 58 wildcat wells were drilled. 53 stratigraphic wells and 58 wildcat wells were drilled.

Results: sub-commercial discoveries in the Nova Olinda reservoirs (1-NO-1, 1-NO-3 e 1-NO-4-AM) and some wells with oil/gas shows.

Phase 2

Petrobras improved seismic method and 36 wells were drilled.

Results: two discoveries: 1-LT-1-AM (Lago Tucunaré) and 1-ICA-1-AM (Igarapé Cuia).

1971 - 1990

Since 1999

After the creation of the ANP, in 1999, Petrobras discovered gas in the well 1-RUT-1-AM which resulted in the fields nowadays under development, Azulão and Japiim.
