Pre-Salt Production // Brazilian Pre-Salt Production - By Well // Production in the Brazilian pre-salt, Jan-10 to Aug-11, well 6-BRSA-639-ESS
October 26, 2011 - by PreSalt.com
Well 6-BRSA-639-ESS (code of ANP - Brazilian National Petroleum Agency), 6-BFR-1-ESS in the nomenclature of Petrobras, which is the operator.
Well located inside the BC-60 block. Petrobras (SAO:PETR3, SAO:PETR4, NYSE:PBR, NYSE:PBRA) is the operator and owns 100% of this block.
This well is located in the Baleia Franca field, pre-salt accumulations discovered in 2008. Is part of the group of fields known as Parque das Baleias, is located 85 km from the city of Anchieta, on the coast of the state of Espirito Santo, belongs to the BC-60 block in the Campos Basin.
The oil is light, estimated at 29° API.
The FPSO Capixaba was responsible for production of this well in the period from Jul/10 to Aug/11, uninterrupted. From Jan/10 to Jun/10 this
well was not production.
Production estimates made by Petrobras in Jul/10, were starting with a production of 13,000 barrels of oil per day and would come at the end of 2010, to 20,000 bpd. As shown in the graph below, this estimate was exceeded in the second month of production (Aug/10) to 21,554 bpd and
25,649 boe. Having reached the maximum production (data available until Ago/11) in February 2011 with 23,419 bpd and 28,724 boe.
In December 2008 the PA announced that Petrobras had found traces of oil and gas in offshore well 6-BRSA-639-ESS and that the discovery was made at a water depth of 1426 meters.
On July 14, 2010, Petrobras announced the start of production in this well, by connecting the 6-BFR-1-ESS with FPSO Capixaba, chartered to
Petrobras for SBM. The FPSO Capixaba previously operated in the Golfinho Field. With the aim of anticipated production in the fields of Cachalote and Baleia Branca, the platform was moved to the set of fields known as Parque das Baleias after changes in its processing plant.
The project adopts groundbreaking technologies designed to operate in the geological conditions of the pre-salt. Among them, new models of flexible risers (pipes for the flow of oil that connect the well to the platform) and new technological solutions to bring the wells into production (Completion).
