A drilling machine is a mechanism which creates holes ( usually called boreholes) and/or shafts in the earth . Drilling rigs may be classified as massive constructions housing equipment employed to drill water wells, oil wells, or natural gas extraction wells or they can be small enough to be removed manually by one human . They sample sub-surface 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 easy movable fittings placed on trucks, tracks or trailers, or more permanent land or marine-based structures ( like oil platforms, generally named ‘offshore oil rigs’ even if they don’t include a drilling rig).

An oil rig on shore would seem to be easier build then one on the ocean. But each drill rig has the elements to work with. There is always quite difficult to get over or deal with. Harsh terrain and isolated areas are common issues . Drilling rigs at one point were semi-permanent. The structures were created on location and were not removed when the well was drilled. Modern oil rigs are custom-made and are portable . They can be moved from a completed well to a new well. It may take weeks to remove an oil rig as they should be taken apart and moved. It takes some time but is not so wasteful then building derricks for every well.

Drilling rigs can be:

Small and portable , such as those used in mineral exploration drilling, water wells and environmental researches .

Big, capable of drilling through thousands of meters of the Earth’s crust.

A drilling rig is used to make holes for oil. Oil rigs need to cut holes or tubes into the ground . Then oilfield equipment is used to remove the black gold. Today’s oil drilling rigs is very technical and complex. The more evasive oil is the more power is put into harvesting it. Deeper oil wells are drilled using more peculiar equipment . More advanced technology is demanded to reach the oil. Having drilling rig does not just drilling a hole and a well and pumping the oil out. Oil rigs demand housing for the staff and storage for supplies and equipment. A oil field site will require electricity and water to run the equipment. A place to process the crude oil is helpful .

The previous drilling rig included drill bits fixed to long poles created of bamboo. The first drill well was in China in 347 AD. The oil was employed to assist create salt. Drilling rigs today consist of huge drills with diamond bits that reach deeper than 1200 m below the earth . Often , the traveling block in an drilling rig on land deal with hundreds of tons of pipe. Massive pipelines motion black gold across spacious quantity of earth . As demand for oil enlarged so did the methods to extract it.
