Oil Drill Rig and Reservoir The rotary drilling rig uses a series of rotating pip es, called t he drill string, to tap into oil reservoirs. The drill string is supported by a derrick, and turned by the rotary table on its oor. Circulating, mudlike uid driven by a pump removes cuttings as the teeth of the drill bit dig into the rock around the reservoir. Reservoirs occur in many places. They form as a result of intense pressure on top of layers of dead marine and land organisms mixed ith sand or silt. This reserv oir abuts a salt dome, hich has trapped a layer of oil and natural gas beteen itself and nonporous rock. !ecause they have no place to expand, the gas and crude oil are under high pressure and ill tend to rush explosively out the channel opened by the drill rig.
