The rig drilling the relief well intended to permanently seal BP Plc's blown-out Gulf of Mexico oil well has returned to the spill site, the company that owns the rig said on Saturday, according to Reuters. "As of our last report, the (Development Driller III) was back on BP's Macondo location," Guy Cantwell, a spokesman for drilling contractor Transocean, said in an e-mail, referring the the ruptured BP Macondo well. The rig had been moved out of the path of Tropical Storm Bonnie on Friday, but the storm has weakened considerably.
