Modern AC Land Drilling Rig

Mast, substructureThis poster depicts typical equipment being

manufactured for mid-depth range drilling, designed for mobility, drilling efficiency, safety, and minimal environmental impact. These “fast-moving” rigs can be transported in predetermined loads that meet permitted dimensions and weights for roads. No cranes are needed for assembly (“self-erecting”); the telescoping derrick 2 and three-piece substructure are lifted by two hydraulic raising cylinders 18 . The substructure’s subbase 19 hasremovable girder sections to provide clearance for the rig to be moved (skidded) along a row of wells for cluster drilling (skids not shown here).

AC driveDeveloped in the early 1990s, alternating-current

drives were first used to drill offshore before being adapted for land. Troll A in the North Sea used the world’s first AC drilling system. AC drives offer more precise speed and torque control and quieter operation. The engine/generator sets 24provide power to the variable-frequency-drive house. The VFD and MCC 25 feed the AC motors 32 that power the drawworks 26 .

Pipe handlingAutomated systems provide a safer work

environment than manual and reduce potential for injuries. Automated pipe-handling equipment reduces the chance of dropped pipe, casing, and tubing used in drilling and completing wells. With a handheld remote control (a redundant control board is at the far end of the catwalk), the driller directs mechanical arms to move tubulars from the pipe racks 15 onto the catwalk 16 . The skate moves individual tubulars up the pipe ramp (V-door) 17 to the drill floor.
