Facts About Drilling Rigs For Sale

By Sherry Gross


There are many natural resources that are very influential in the rise and fall of economies. One such resource is the black gold or petroleum. They can be found in choice locations, and these lucky lands who get to access it from under the ground will undoubtedly make millions. With the rise of vehicles and other petroleum powered equipment, it is suffice to say that the one who has the oil rules the world.

Oil is a neutral and nonpolar chemical substance that is both hydrophobic or water fearing and lipophilic or fat loving at the same time. It can be animal, vegetable or petrochemical in origin. Mineral oils such as the most coveted supply of petroleum come from ancient fossilized organic materials like zooplankton and algae. To be able to draw it out from underneath the surface, one must use drilling rigs for sale to make holes in the ground.

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.

These tools also come in a variety of sizes, all depending on the kind or level of need of the one who will have to utilize it. For drilling small holes, an auger is typically used because it can be easily manipulated by a single individual. These small ones have high mobility due to their compact sizes, and is mostly the pick for environmental investigation and mineral exploration undertakings.

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.

Not all of them are planted permanently on land. True, there are those found on land like the oil reserves in the Middle East. But, others are situated on a marine based structure, also known as offshore oil rigs. Some are in the form of mobile equipment that are then mounted on trucks and trailers.

There are several types of drills, all serving different purposes. The land rig is the one used in the oil field. They are used to make holes in the ground for quick and easy extraction of the very costly liquid substance. They can come in all sizes, as aforementioned.

There are also those which are mounted on something else, in the absence of good old solid earth. This particular type is known by everyone as the barge rig. The drill is conveniently perched on a barge for easy shallow water drilling.

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.
