$this->bbcode_second_pass_quote('', 'T')upi test flows 'capped at 14,000 bpd'
News wires
Petrobras is unlikely to produce more than 14,000 barrels per day during extended well tests at the Tupi field, in the Santos basin's pre-salt fairway, the Brazilian giant's chief financial officer Almir Guilherme Barbassa said.
The tests, which will run for 15 months, are being carried out from the floating storage, production and offloading vessel Cidade de Sao Vicente.
"While the platform capacity is 30,000 bpd, we do not expect to produce more than 14,000 bpd due to limits on the amount of gas we may flare," BNamericas quoted Barbassa as saying in a webcast.
Petrobras aims to gather "important" information from the testing, such as the long-term behavior of the producing reservoir and information on fluid flows and drainage, subsea outflow and the geometry of final wells, he added.
The project poses many challenges but so far has met expectations, Barbassa said, adding: "We continue to remain as optimistic as ever about the economic viability of this reservoir."
Challenges at Tupi include operating christmas trees at record water depths and reinjecting carbon dioxide associated with fluids produced in the reservoir. Completing wells in the high-pressure environment and acquiring high-resolution seismic will also be difficult.

The Tupi long-duration test (LDT) will be the first in a series to be set up in the Santos Basin pre-salt areas. By 2013, Petrobras is scheduling the installation of no less than 18 LDTs in the region, all designed to expand understanding of the carbonatic reservoirs that have been discovered.
The plan is to test the behavior of the main pre-salt areas, before choosing a pilot or definitive systems. The list, which includes the recently inaugurated Tupi system, call for projects in the Iara, Guará, Carioca and Parati areas, as well as in discoveries still being evaluated and in initial stages.
According to the Petrobras timetable, the second pre-salt LDT to enter into operation will be designed for either Iara or Guará. The definitive location will be decided upon before the end of the first half of this year.
Because the LDTs do not involve making use of the gas that is developed, the new systems must be approved by the National Petroleum Agency (ANP) in order for the regulatory agency to determine the percent that is liberated for flaring off. It is more probable that the projects will be authorized following the Tupi model — that is, with flare off authorized for 500,000 m3/day of gas.
