Local chiefs from the Upper Nile state await the arrival of South Sudan's Petroleum and Mining Minister Stephen Dhieu Dau (not pictured) during a ceremony to restart oil production at the main oil field in Palouge after a 16-month shutdown May 5, 2013. South Sudan's Palouge oilfield, the country's biggest, will reach production of up to 180,000 barrels per day within a month after starting at 125,000, oil consortium Dar Petroleum said on Sunday, ramping up output slower than initially planned.STRINGER/Reuters
