RIO DE JANEIRO, Sept 8 - Brazilian state-run oil company Petrobras said on Tuesday it has restarted test production at the Tupi oil field after an equipment problem forced it to halt operations in early July.
The massive Tupi field holds 5 billion to 8 billion barrels of oil and is one of the most promising in Brazil's offshore subsalt province, an area the South American nation hopes will turn it into a major energy exporter.
Petrobras halted test production of around 14,000 barrels per day in Tupi to replace a sub-sea well flow control device.
"The device was replaced successfully in less than two months," company said in a statement.
Oil companies have been drawn to the massive reserves of the subsalt cluster, but analysts point out there are still considerable risks in the development phase that could slow the operations or make them more costly than expected.
