Oil Drilling Rig

A drilling rig is an integrated system that drills wells, such as oil or gas wells, in the earth's subsurface.

Drilling rigs can be massive structures housing equipment used to drill oil wells, or natural gas extraction wells,   Drilling rigs can sample subsurface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called 'offshore oil rigs' even if they don't contain a drilling rig).

Small to medium-sized drilling rigs are mobile, such as those used in mineral exploration drilling, blast-hole, water wells and environmental investigations.     Larger rigs are capable of drilling through thousands of metres of the Earth's crust, using large "mud pumps" to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled.

Hoists in the rig can lift hundreds of tons of pipe.  Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas;   and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred).

Offshore rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.
We can supply rigs drilling from 500-9000 meters depth, both drived by rotary table and top drive system, Including the skid mounted rig, track mounted rig, workover rig and offshore rig.
