HOUSTON, Jan. 11 -- State-owned Petróleo Brasileiro SA (Petrobras) said a well drilled within Golfinho field boundary areas in Brazil's offshore Espírito Santo basin penetrated sandy formations about 90 m thick saturated with high-quality light oil.
The 3-ESS-156A well was drilled as part of the delineation of discoveries on the former BES-100 block (in National Petroleum Agency's Bid Zero). Work on the well will be concluded this month. The well is 65 km off Espírito Santo state on the same block as the 1-ESS-123 well—about 12 km away—that discovered Golfinho field.
The 3-ESS-156A, in water 1,322 m deep, was drilled to 3,402 m TD. Sandy formations were detected with "excellent traces of oil and natural gas," which were subsequently confirmed by electric logs. Petrobras is performing a final well evaluation.
Production from Golfinho field is scheduled for 2006.
Petrobras, which expects 50% of the new reserves in the Espírito Santo basin to be light crude, is investing $6 billion in Espírito Santo state through 2010 (OGJ Online, Oct. 1, 2004).
