Brazilian oil and gas company OGX Petroleo e Gas Participacoes has discovered hydrocarbons in the Santonian, Albian and Aptian sections of exploration well 1-MRK-3/4P-RJS in the shallow waters of the Campos Basin, offshore Brazil.

The well is located in the BM-C-37 block, in which OGX holds a 50% working interest with Maersk Oil, the operator, holding the remaining interest.

Hydrocarbons were encountered in sandstone reservoirs in the Santonian section totaling about 14m of potential net pay.

In addition, about 43m and 12m of potential net pay were encountered, respectively, in carbonate reservoirs in the Albian and Aptian sections.

The 1-MRK-3/4P-RJS exploration well, known as Carambola-A, is the first of two wells to be drilled in the BM-C-37 block and the drilling of this prospect was concluded at a final depth of 3,400m below sea level.

The well is situated about 74km off the coast of the state of Rio de Janeiro at a water depth of approximately 134m.
