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.

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.

Size wise, some come in small and medium sizes and are very mobile. These are the types used in mineral exploration drilling and other environmental investigations. They can also be very huge and are highly capable of boring through thousands of meters into the crust of the earth.

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.

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.

Platform rigs are immobile structures that are found offshore. These are the structures from which development wells are drilled and produced. Since they are not on solid ground, the platforms should be rigid and are basically rule compliant. They can either be made of steel or concrete. Semi submersible ones, on the other hand, is also a kind of an offshore rig. They are floating structures with pontoons. They can work with ten thousand cubic feet of water depth.
