Two oil majors, UK-headquartered energy giant Shell and its U.S.-based rival, Chevron, are returning personnel to their offshore assets in the Gulf of Mexico and all rigs to drill sites in a bid to resume operations since the anticipated disturbance, which was expected to turn into a hurricane, is no longer considered to present a safety risk.

Shell began transferring non-essential personnel at its Appomattox , Vito , Ursa , Mars , Auger , and Enchilada / Salsa assets to shore on November 4, as a precautionary measure after the hurricane threat appeared on the horizon in the Gulf of Mexico.
