Petrobras Halts Production At 13 Rigs

Petrobras halted output at 13 offshore rigs on Thursday in the Campos Basin Area to check for leaks after an oil slick was discovered on the ocean surface in the area.

The stoppage results in output losses of 135,000 barrels of oil and 830,000 cubic meters of natural gas per day, or nearly 10 percent of Petrobras' daily output.

"There is no production there now. When it will be resumed depends on when we find the leak," said a Petrobras spokesman. "Probably tomorrow production will remain halted."

Petrobras reported that the leak off shore Rio de Janeiro was relatively small, approximately 98,000 liters (26,000 gallons) of crude.

The company said in a statement it was yet unclear where the oil, which formed a thin layer on the ocean's surface, had come from, but was suspecting a leak from one of the offshore platforms or tankers.
