Nabors Industries Ltd
A global drilling contractor that operates land and offshore rigs and builds drilling technology, software, and equipment — including brands like ROCKit, SmartNAV, and Canrig — for oil and gas companies worldwide. The company traces its roots to 1952, when Clair Nabors took over a Canadian drilling firm and renamed it after himself. In 1963 it drilled the discovery well for ARCO in Alaska's Prudhoe Bay field, helping open one of North America's great oil finds.
