Petrobras achieved a 100% geological success rate in the pre-salt layer in 2013.The presence of oil was found in all 14 wells drilled last year in the Santos and Campos basins, all operated by the company. Considering all offshore wells drilled by the company, in both pre-salt and post-salt, the exploration success rate was 77%.

Between January 2013 and March 2014 alone, Petrobras made 49 new discoveries, including 15 in pre-salt. Petrobras’ strong results in pre-salt exploration are due to its in-depth knowledge and technological excellence in ultra-deep water exploration.

By using its experience in Campos Basin, adapting solutions to the pre-salt conditions of Santos Basin, together with continuous large-scale investment in the acquisition of exploratory data, the company has been able to better characterize reservoirs and reduce production design uncertainties.

The pre-salt discoveries are some of the most important in the world over the last decade. Besides presenting very significant potential volumes, the presence of excellent quality oil of high commercial value has been detected in them.
