What You Need To Know About Drilling Rigs For Sale

By Sherry Gross


There is no contest to fact that oil or petroleum is one of the most utilized substance in various fields of work and study. It is considered by many to be liquid gold, as it prices quite high in the world market. To be involved in the said industry would mean bringing home millions after millions of money more than what you could possibly spend, and it is due so that people go to such areas bringing along drilling rigs for sale, wishing to chance upon a treasure mine of sorts.

Oil is both hydrophobic and lipophilic, meaning it is downright immiscible with water but can be mixed easily with other oils. The type that is drawn from underneath the surface is a type of mineral oil, it is made from fossilized remains of organisms such as algae and zooplankton. Other types include those that come from plant and animal sources.

As aforementioned, a drilling rig is a machine that bores holes. Through these holes, black gold is drawn out, processed, and then exported to petroleum users all over the world, especially oil companies who sell them off to motorists and others who may need them. They also come in various sizes, according to the level of need by the one who has to use it.

They can be small and compact. This type is called an auger, and it can be operated by a single person alone. It is also very movable. The one who has to use this type often does not need any assistance as he can move it on his own without any particular difficulties. These small ones are also used in small scale projects such as mineral exploration and other investigative purposes.

They can also be relatively humongous that it is very much impossible for one person to operate it alone. These big monsters can bore holes in the ground, be it thousands of meters deep into the crust of the planet. These are mostly used for oil related uses.

They are not only used to draw oil from underneath though, contrary to what the majority of the public may be thinking. They can be used to make wells for that fresher supply of water from underground. They can also be used in the extraction of natural gas. Installation of sub surface structures such as tunnels and other utilities also need a rig to do the first step in their installment procedures.

Rigs also come in a variety of forms according to need. Those that are permanently and firmly planted on solid ground are called land rigs. These are extensively used in every oil venture and undertaking.

There is also one type that is mounted on a huge vessel, say for example, a barge. This so called barge rig is made up of the drill that is securely fastened onto the marine vessel. This is used exclusively to drill holes on shallow waters.

Offshore rigs are more or less like the barge types, as they are not found on land. Platforms of solid concrete and steel can also house such an equipment. The semi submersible kind allows for the submersion to a required depth of about ten thousand feet.
