BP has completed a successful flow test on its Itaipu pre-salt discovery off Brazil that indicates commercially viable flow rates.
A drill stem test carried out on the BP-operated Itaipu-1A discovery well in block BM-C-32 in the deep-water Campos basin recorded flow rates of up to 5600 barrels per day of oil over a 32-hour period through a 40/64 choke from a limited perforated interval, the UK supermajor said.
It further stated that results from pressure build-up after the main flow indicated “good connectivity in the reservoir”.
“This is a good result for the Itaipu project, indicating that commercially viable flow rates can be achieved from this pre-salt carbonate reservoir,” said BP’s vice president for Brazilian exploration, Neil Piggott.
The flow test was the latest activity in ongoing appraisal work at the 2009 discovery located about 125 kilometres offshore that was acquired by BP as part of its purchase of Devon Energy’s Brazil assets about two years ago.
The British player drilled the Itaipu-2 appraisal in 2011 and is targeting a second appraisal, Itaipu-3, later this year after gaining approval from Brazil’s National Petroleum Agency.
BP holds a 40% operated stake in the block, with partners Anadarko Petroleum (33.3%) and Maersk Oil (26.7%).
