Petrobras concluded work on test well 3-RJS-621 where it discovered light oil with a 33° API. This discovery is in the state of Rio de Janeiro, about 160 km from Rio de Janeiro. Drilling took place in 1,332 m of water.
The 3-RJS-621 well is in the Santos basin in an appraisal area of the former BS-500 block where a large gas find had already been made. In addition to discovering a further oil source, this well has corroborated the gas finds made from drilling well 1-RJS-587.
The new well identified an 40-m thick sandstone reservoir containing light oil. Appraisal tests made in these reservoirs confirmed good quality oil and a high production potential.
Petrobras is appraising the volumes, although this find is of particular significance given that it is light oil that has been discovered in a region where reserves of gas and condensate had already been detected.
