Brazil: OGX DSTs gas-condensate on Santos shelf | Oil & Gas Journal

OGX Petroleo e Gas Participacoes SA, Rio de Janeiro, gauged gas-condensate on a drillstem test in the Santonian section of the 1-OGX-11D-SPS well on the BM-S-59 block on the Santos basin shelf off Brazil.

The well, in 180 m of water 84 km off Rio de Janeiro, in June encountered a 180-m column with 75 m of net pay in the Santonian section of what OGX calls the Natal accumulation. The late September drillstem test flowed gas and 47° gravity condensate that OGX said “should be responsible for more than 20% of the hydrocarbon volume of this structure.

The company said the test results indicate a production potential of 1 MMcmd and 1,200 b/d in a vertical well or as much as 5 MMcmd and 6,000 b/d in a horizontal well.
