Further testing on the huge potential of the pre-salt play offshore Brazil is about to get underway with a extended well test on the Iracema field in the Santos Basin.

A six month testing programme is about to commence using the FPSO Cidade de São Vicente – supplied by Norway’s BW Offshore – which has been connected up to the RJS-647 well in a water depth of 2,212 metres (7,255 feet)  offshore Brazil.

During testing, technical data will be obtained on the reservoir flow characteristics, and oil flow in the subsea flow lines connected to the FPSO, project partner BG said today.

“During this initial test phase the well is expected to produce at around 10 000 barrels of oil per day, constrained by facilities – as authorised by Brazil’s National Agency for Petroleum, Natural Gas and Biofuels,” BG states.

“The well test is part of BG Group’s fast-track development of its interests in the world class pre-salt Santos Basin discoveries and prospects,” said the Reading, UK-based company.

Information gained during the test will support development of a final production system for the area which is expected to be in operation by the end of 2014 with the installation of the 150 000 bopd capacity FPSO Cidade de Mangaratiba, BG has indicated.

Petrobras operates block BM-S-11 with 65% where the test is taking place, and BG holds 25% interest and Petrogal Brasil S.A. 10%.
