• Driller: The one person who actually operates the rig.
• Derrickman: Two jobs: monitors and records the condition of the drilling mud, handles the top of the pipe. • Roughneck or Floorman: handles pipe on the rig floor • Roustabouts: Loading and unloading of the equipment and supplies.
Developed in the 1850’s, gained widespread acceptance after the Spindletop well was drilled in 1901.
Classification of rotary drilling rigs
Drilling Rigs
Semi-Submersible Drilling Rig
The lower the pontoons lie beneath the surface of the water, the less they are affected by wave action. This reduces vertical movement and allows drilling to continue in moderately rough seas. A semi-submersible vessel is normally held in position by up to eight very large anchors, or by dynamic positioning. Dynamic positioning systems use computer controlled directional propellers to keep the vessel stationary relative to the sea-bed, compensating for wind, wave or current. Semi-submersibles can drill in water depths to 300 meters or more all year round.
Drillship
Drillship
Drill ships have a broadly conventional ship's hull, but also feature a large aperture, known as a "moon pool", through which drilling takes place. Either purpose built, or converted from some other use, drill ships can be moved easily between locations. They can carry large stocks of supplies, but are not as stable as semisubmersibles. Drill ships use either anchors or dynamic positioning to maintain station. The latest drill ships can operate in 1,500 meters of water.
Semi-Submersible Drilling Rig
A semi-submersible drilling rig is normally a self-propelled working platform supported by vertical columns on submerged pontoons. By varying the amount of ballast water in the pontoons, the unit can be raised or lowered in the water.
Jack-up Unit
A jack-up unit is a barge with legs that can be lowered or raised. The barge is towed to the drilling location with its legs in the raised position. Once in position, the legs are lowered. When they reach the sea-bed, the barge's body is hoisted above the water, creating a stable drilling platform. The length of the legs determines the depth of water in which a jack-up barge can be used. They can generally be used in up to 100 meters of water. Jack-up barges are widely employed in the relatively shallow waters.

Drill at Sea
Rotary Rig
(Fluid Circulating)
By itself, rotating a bit on pipe is no better than dropping a bit on cable. A fluid circulating rotary rig circulates fluid while the bit drills.
Common water depth limits 4,000 feet

Cable-tool Drilling - Old Style
• Cable-tool Drilling: The drill bit hangs in a rope or cable. A powered walking beam raises and drops the cable; it hits the bottom of the hole with great force to pierce the rock. • Two disadvantages: driller must stop drilling frequently to remove pieces of rock or cuttings. The method can not drill soft-rock formations.
• Drilling crews have to operate through the depth of the sea water column. • Climates & Environments
• Corrosive to machines
• Limited Storage space
• Vessel dynamic positioning
