The drilling rigs are used to create holes in the surface of the earth intended for extraction of natural gas, oil wells, drilling water wells and these machines are massive but there are other small ones which can be moved manually by one individual known as augers.
They are also used to install underground utilities as well as instrumentation and sub-surface fabrications.
They are usually mounted on mobile trailers, tracks or they may be permanently placed on land and there also others which are mounted on structures that are marine-based.
The term rig is normally an equipment that is complicated and is supposed to be used to drill the earth’s surface.
Large drilling rigs have the capability of utilizing some large mud pumps which circulates some slurry via the drill bit so as to remove the cuttings when the drilling is going on and it also cools the drill bit.
There are some equipment that forces some sand or acid into the reservoir so as to enable the extraction of the natural gas or oil and in locations that are remote there are crews who are permanently located on the site and the marine rigs might drill up to thousands of miles down the sea but needs few crew who work in cycles or rotations.
Where there are deserts they have helped to extract water that is used for drinking as well as for immigration purpose.
Tall hotels and resorts also use the services of mobile drilling companies to drill bore holes which helps them to have enough water especially for bathing of their building has many stories and the water that is supplied by counties or the government is not enough or does not have enough pressure to get to the top stories.
Mobile tracks or trailers which are mounted with drilling rigs helps the drilling to be done even in faraway places and this drilling rigs are small but they can be capable of drilling up to thousands of meters below the service of the earth and they are usually meant for extracting water, and also for purposes of testing the soil below for minerals.
The cost of the drilling rigs depending on the intended use since they are usually custom made for diverse uses and the drilling bits are made in such a way that they can with stand very severe heat when they turn round in high speed when drilling even very hard rocks to penetrate the earth.
Drilling rigs are made with tough metal such as hardened steel and the drill bits are made of diamond since it is very hard and this enables the drill bits to create a hole even in very hard rocks.
