RIO DE JANEIRO -- Production in the pre-salt layer of the Santos basin has begun via an extended well test (EWT) in the block BM-S-11, according to Petrobras.

The Tupi EWT will kick-off production via well 1-RJS-646 which is connected to FPSOBW Cidade de São Vicente. The FPSO has a production capacity of 30,000 b/d of oil.

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

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 bbl of oil and 4 MMc/d of gas. The first definitive module for the development of the area may be an extension of the pilot project, the company says.
