Petrobras says that the first well drilled in ultra deep Sergipe-Alagoas Basin waters identified the presence of hydrocarbons similar to those bearing oil in deep Campos Basin waters. It is a discovery of a new oil province in the Sergipe-Alagoas Basin.

This location confirms the existence of large accumulations in the distal portions of this basin, implying that there are greater volumes than those found in the shallow water fields (Guaricema and Dourado). Profile data point to the presence of light hydrocarbons.

This well, called 1-BRSA-851-SES (1-SES-158), known as BARRA, is located in Block SEAL-M-426, in the BM-SEAL-11 concession, northeast of the Sergipe sub-basin, at a water depth of 2,341 meters, 58 km off the coast of the state of Sergipe.

Well 1-SES-158 tested deposits in an accumulation developed in an area of some 70 square kilometers. The nearest analogous field, Piranema, is located 90 km away. This well, which is still being drilled, will continue sampling older and deeper reservoirs.

After the drilling has been completed, the consortium formed by Petrobras (60% - Operator) and IBV-Brasil (40%) to explore the BM-SEAL-11 concession will continue its activities and investments by drilling other wildcat wells and preparing the Discovery Evaluation Plan to be defined by the ANP.
