The French-owned independent drilled on four deep-water blocks in the Espirito Santo basin, but with disappointing results.
Only one of the four wells, on Block ES-M-529, found hydrocarbons, but this was relatively tight gas, considered to be stranded in a deep-water location, with a weak case for commerciality.
Perenco sub-let the Diamond Offshore semi-submersible Ocean Star from block partner OGX, but the rig has since been chartered by Queiroz Galvao Exploration & Production (QGEP).
