In a normal scenario, gas/oil-drilling (exploration) companies rent or lease the rigs from another company that owns the rig, the drilling contractor. The majority of the personnel on the drilling rig, called 'the rig crew', are employees of the drilling contractor. The company man is the on-site representative of the operating/exploration company and is in overall charge of the drilling and associated activities. Rig operations and maintenance and crew upkeep are attended to by the toolpusher, who works for the drilling contractor.
