Production from the giant Roncador offshore oil field in Brazil's Campos Basin continued on Nov. 4 after workers on the field's production vessels joined a four-day strike, an oil workers' spokesman said, denying media reports of an output shutdown.

Tezeu Bezerra, head of communications at Sindipetro Norte Fluminense, which represents workers on Roncador platforms, said the strike did not stop output at the P-52, P-54, P-55, and P-62 floating production vessels which were operating under management contingency plans.

Bloomberg News, citing unnamed sources, reported earlier that production of Roncador crude had been halted on those platforms after workers joined the strike.
