Santos Basin Guara contains 1.1 to 2.0 billion recoverable barrels

BG Group (30%) and partners Petrobras (45%, operator) and Repsol (25%) have today announced that the Guara discovery in the Santos Basin pre-salt, offshore Brazil is now estimated to contain recoverable volumes of 1.1 to 2.0 billion barrels of oil equivalent. During its drill stem test, Guara flowed at 7 200 barrels of oil equivalent per day (boepd). These flow rates were facilities-constrained, and test data indicates that a permanent production well would be capable of producing initial rates of up to 50 000 boepd, providing further evidence of the robust economics of this pre-salt play.

BG Group and partners have agreed a schedule which will prioritise the installation of production facilities on Guara. The development will use a 120 000 barrels per day Floating Production, Storage and Offloading vessel (FPSO), targeting first production from 2012. This will follow the 100 000 barrels per day first phase of the Tupi field, due onstream at the end of 2010 (BG Group 25%, operator Petrobras 65%, Galp 10%).

BG Group Chief Executive Frank Chapman said:” The well test results on Guara were excellent and underscore again the outstanding potential in BG Group’s extensive position in the world-class Santos Basin.”

“Partners are fully aligned on continuing work to accelerate the full appraisal and development of these resources, with activities ongoing and planned at Tupi, Abare-West, Corcovado, Iracema, Iara, Carioca and Parati. It is clear that the Santos Basin pre-salt will make a very material contribution to the production and cash flow of BG Group for many years to come.”
