The Truth About Drilling Rigs For Sale

By Sherry Gross


Oil is undoubtedly one of the most coveted natural resources today. It is the dream of every country to find a deposit of oil within their boundaries, as it is bought by other countries at very high prices. It is even dubbed today as black gold, as they rake in millions worth of profits as it is a crucial substance in modern economy. Those who think they have found such a treasure mine waste no time in buying drilling rigs for sale and other related equipment.

A drilling rig is a machine that creates holes in the ground. It is essential for oil rich companies, as they are used to extract the said substance from under the ground. They can be as big as a tower or they can be small enough to be operated by one person. These small ones are more commonly known as augers.

To be able to extract oil from below the crust, one must drill very deep holes first. As the said substance is typically found very deep below, it will be impractical to have men dig thousands of feet in order to reach a reserve. To be able to do this quickly and easily, drilling rigs are used. One the holes are dug, the oil will be sucked from below and will be transported to plants where they will be processed.

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.

There are many different kinds of this special equipment. Each type caters to different needs. The first type is the one which is the most common. Land rigs are basically used in the petroleum industry. They are used for boring to the ground to make oil wells and can come in different sizes, according to application.

The second type is more commonly known in the commercial industry as barge rig. As its name implies, it encompasses of a drilling mechanism that is safely mounted on a marine vehicle, which in this case is the barge. They are most often used to dig in a shallow water depth.

Offshore rigs do not stand on land, neither are they mounted onto a moving vehicle nor vessel. Two known offshore types include the platform and semi submersible rigs. The former features the rig that is mounted on a secure platform of concrete or steel. The submersible type can still function even when immersed in water up to ten thousand feet.
