The development stages:Exploration drilling/2017-04.CE-M-661 is a 768 square kilometers offshore block in the Ceará basin, northeast Brazil. The block was originally acquired in Brazil's 11th bidding round in 2013 by operator Total E&P Brasil (45%), Queiroz Galvão (25%) and OGX (30%). OGX later relinquished its participation in the block, and Premier Oil acquired its stake. Local content defined by ANP at the round was 37% for the exploration phase and 65% for development. Petroleum Geo-Services was hired to carry out a 3D seismic survey. The exploration program at CE-M-661 involves the drilling of one well prospecting for oil and/or gas. If hydrocarbon shows are found in this first well, Total is likely to drill one-to-three new wells in the same block. According to regulator ANP, 135mn reais will be invested in the minimum exploratory program (PEM).
