DRILLING RIG Modern drilling equipment is consolidated and classified under the term of a "drilling rig". A drilling rig is not a single unit but is composed of a series of integrated parts which work together to keep the bit on bottom. Rotary drilling bits are available today which effectively cut through the crust of the earth. The drill string, made of tough steel pipe, turns the bit and channels the drilling fluid down to lubricate it and carry the cuttings away. The bit must be replaced when it wears out: and there has to be a connection between the surface and the bit on bottom. On any rig there are a large number of water, mud and air lines which must be installed. Rigs are built to certain capacities, depending on the size of the draw works. They will drill effectively to a given depth, varying with the size of the drill pipe used, the size of the pump and weight of the casing to be run. They are usually specialized for a particular area. At present the assembly of the drilling equipment and derrick is done by the industrial method. The drilling equipment is mounted on three metal platforms, which are moved from one oil well location to another as need arises. 1.
