Petrobras announced that the production in the Pre-Salt layer of the Santos Basin will start tomorrow, by means of the Extended Well Test (EWT) in the Block BM-S-11, operated by Petrobras (65%) in partnership with BG Group (25%) and Galp-Energia (10%).

The Tupi EWT will kick-off production via well 1-RJS-646, at a depth of 2,140 meters from the water depth, which was connected to FPSO BW Cidade de Sao Vicente which has a production capacity of 30,000 barrels of oil per day.

The purpose of the test, which will last 15 months, is to collect technical information for the development of the pre-salt reservoirs, such as: the behavior of the reservoirs in long-term production; fluid movement or draining during production; underwater offloading; studies to define the best geometry for the final wells, which may be vertical, horizontal and/or deviated.

With the beginning of the Tupi EWT, Petrobras starts the development of a new exploratory frontier, constituted of oil reservoirs in microbial-type carbonatic rocks located at a depth of some 5,000 meters from the seabed and over 2,000 meters from the water depth. Located more than 300 km from the coast, the development of this area will require a new, complex logistics model not only to transport people and equipment, but to store and offload production.

The FPSO installed for the EWT will be connected to two wells, testing the well 1-RJS 646 in the first nine months and the second well 9-RJS 660 in the remaining six months.

After the EWT is completed, the Tupi Pilot Project will start-up, with a capacity to produce and process 100,000 barrels of oil and 4 million cubic meters of gas per day. The first definitive module for the development of the area may be an extension of the pilot project.

The Tupi area, which accumulates high quality oil, medium to light (28 degrees API), will provide subsidies to Petrobras' technical staff for the future production development projects for the pre-salt area.
