UPDATE 1-Brazil oil union says Petrobras pushing back against strike
(Adds Petrobras Friday strike-related oil output reduction estimate)

RIO DE JANEIRO Nov 7 (Reuters) - Brazil's state-run oil company Petroleo Brasileiro SA is increasing efforts to weaken the impact of a five-day strike, taking back control of at least two offshore oil units from striking workers, the main union behind the walk-out said on Friday.
In the Campos Basin northeast of Rio de Janeiro, workers were fully or partially in control of 46 maritime units on Friday, down from 48 on Thursday, the country's largest oilworkers union confederation, known as the FUP, said in a statement.
Maritime units include production platforms, drillships and other offshore oil vessels. The Campos Basin accounts for about two-thirds of Brazil's oil output.
The reduction in offshore units under union control came as Petrobras won court orders blocking union members from interfering with the work of management contingency teams.
Late Friday, Petrobras said in a statement it had reduced strike-related production cuts to 115,000 barrels a day, or 5.5 percent of pre-strike output, from 127,000 barrels a day on Thursday.
FUP workers began striking Sunday afternoon seeking to derail a company plan of investment cuts and asset sales that they have criticized as a plan to sell off the company to foreigners at bargain basement prices.
The FUP said Petrobras is underestimating production cuts. The union has estimated that the strike is affecting 400,000 barrels of oil output a day but has declined to say which platforms or fields have suffered production cuts and by how much. Continuación...
