Circulation of drilling fluid (mud) serves several functions on a rig, including cooling the bit, providing hole stability, and aiding in formation evaluation. A crew working on a triple is able to pull three lengths of pipe out of the hole before unscrewing the pipe. Pits are named for their function (e.g., shale pit, settling pit, volume pit, mixing pit, and suction pit). This page was last modified on 7 January 2016, at 13:36. There also is increased interest in accessing these formations at an angle: rig crews drill a well bore that curves toward a drilling target. Joints of drill pipe and casing are rolled from the pipe racks where they are stored on the catwalk and hoisted up through the slide (21) and V-door. It was over 100 degrees in North Central Oklahoma when the crew set up this drilling rig. The drill stem is itself heavy the drill string is suspended by a cable and tends to act like a plumb bob when it is raised and dropped. However, the mud system does not move with the mast and substructure, as with desert rigs. The drill string refers to the combination of drill pipe, collars, and other bottom hole assembly components. Canadian drilling rigs meet some of the highest regulatory and safety standards in the world. The catwalk is the deck located to the side of the derrick floor and between the pipe racks (22).
