The Cidade de Angra dos Reis FPSO, which is initially connected to well RJS-660 (known as Tupi-P1), is expected to produce up to 100 000 barrels of oil per day and up to 177 million standard cubic feet of gas per day.

The Tupi-P1 FPSO is located close to the 3-RJS-646 well (known as Tupi Sul) where the FPSO Cidade de Sao Vicente has been conducting an extended well test (EWT) since May 2009.

BG Group chief executive Frank Chapman said that the exploration and appraisal program, and subsequent analysis to date, confirms the huge resource potential, excellent reservoir characteristics of the Tupi/Iracema discovery.

"Extended well testing and the commissioning of the first permanent Tupi facilities, delivers tangible momentum and certainty to our development plans in a play that underpins a substantial part of BG Group’s growth plan extending over the next decade," Chapman said.
