The rotary table is also called a turntable. Most rotary tables are chain driven. These chains resemble very large .
A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm). AlternativesMost recently manufactured rigs no longer feature rotary drives. These newer rigs have opted for technology. In top drive, the drill string is turned by mechanisms located in the top drive that is attached t. [pdf]
Rotary drills, on the other hand, make the bit penetrate the bedrock by quasi-statically pushing the bit into the bedrock. It is therefore the down pressure (thrust) on the bit that contributes significantly to. [pdf]
Rotary impact drilling tools have the effect of impact force in drilling, and have higher ROP than traditional PDC and RCB bit. However, the tool has a high requirement for the strength of the bit and needs. [pdf]

This article lists the main components of a petroleum onshore drilling rig. Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but. .

From 1983 to 1993, the rig was operated by in . She was mothballed in 1993, and in 2005 she was acquired by and underwent intensive refurbishment. In January 2006, Shell awarded a contract to manage and operate Kulluk to Frontier Drilling (now part of ). [pdf]
