Ceará Basin

Located in the shores of Ceará State, in the eastern section of the Brazilian equatorial margin, Ceará Basin is still considered to be a new frontier basin, even though it produces an oil and gas in its shallow waters. It has an offshore area of approximately and borders Alto de Fortaleza and the Potiguar Basin to the South, and Alto de Tutoia and the Barreirinhas Basin to the North. The drilling activities in the offshore portion began in 1971, and the first discovery took place in 1977 in Xeréu Field’s shallow waters. There have not yet been commercial discoveries in the deep waters of this Basin, though notices of discovery of the rift sections of the reservoirs have been filed with the ANP.



According to data from the ANP disclosed in 2013, this Basin is amongst the top ten responsible for the production of oil and gas in shallow waters in Brazil, with prospects for discoveries of light oil in deep waters. It is comprised of four fields - Xeréu, Curimã, Espada, and Atum – which are operated by outsourced companies, reaching a production of  of oil and  of natural gas in 2012.

Block CE-M-661

QGEP owns a 25% share of the consortium for Block CE-M-661, which were acquired in the 11th ANP Bidding Round in May 2013.

The block is located in deep waters, and the expected prospect is similar to that which resulted in discoveries in basins in West Africa (Ivory Coast and Ghana), the French Guiana, and in the Brazilian states of Sergipe and Alagoas. The main reservoirs are located in the superior Cretaceous interval, and the source rocks are from the Cenomanian-Turonian boundary section in the post-salt sequence.

Under the minimum exploration program established with the ANP, there were commitments to obtain 3D seismic for the whole block, as well as one exploratory well. In regards to the local content, the commitment is 37% in the exploration phase and 65% in the production phase.

3D seismic data has been acquired and processed. The Consortium is interpreting this data and evaluating the Block's potential.
