Output at Iraq's Rumaila oil field has been cut to 530,000 barrels per day - down from about one and a quarter million - after two bombs blew up pipelines.<br/> As a result of the blasts some production has been completely halted at the Basra site.<br/> The twin explosions hit Rumaila's pipeline network late Friday.<br/> Police say they found evidence the explosives were planted beneath the pipes.<br/> Basra, which handles the bulk of Iraq's oil exports, has generally had fewer attacks than other Iraqi cities.<br/> Rumaila, the workhorse of Iraq's oil industry, has estimated reserves of around 17 billion barrels, and produces the bulk of Iraq's total output of 2.9 million barrels per day.<br/> Travis Brecher, Reuters
