The earth has become a better place to live on thanks to the many discoveries of mankind which has very well improved the lifestyle of the modern man. There had been many breath taking discoveries and many precious metals and commodities have been excavated from mother earth till now.
Though most of these commodities like metals have been used for many industrial applications nothing can be compared when it come to the usefulness of crude-oil. Indeed this has been the most valuable commodity that has been drilled out from earth and which has readily changed the lifestyle of human beings. In today's world anything we use for our daily purpose is indirectly linked to this precious commodity crude_oil. In today's world the largest producers of this precious crude oil are the countries of Saudi Arabia, Russia and followed by United States of America.
If we go deep into the chemistry of the crude-oil, it can be said that it is made up of a hydrocarbon mixture. It is found as a liquid in its natural form and found within the formations of earth's crevices. The crude oil is otherwise called as petroleum and it has been found within the porous rock formations deep inside the earth due to the decomposition of the dead organic matter millions of years ago.
Once this oil is distilled then a variety of lubricants and petrochemicals are obtained from them. The products that are obtained by the distillation of the crude-oil includes kerosene, diesel, fuel oil and various other types of by products that all are used in the different chemical industries world wide. The crude-oil that is drilled from the different locations of the earth is found to vary much in their density, viscosity and composition. This is the main reason that attributes to the variation of the quality of the oil obtained from the different countries.
The best quality oil till now has been concentrated in the Gulf countries and hence they are priced very high. Hence the Gulf countries have a high demand for their high quality oil. The drilling process for the crude oil is indeed a very tedious and time consuming process and it has been reported that the oil drillers drill as far deep as 6 miles into the earth's crust for pumping out this valuable fuel. Such an oil exploration costs the oil exploration and drilling companies millions of dollars each year. They do bear all these costs since they know very well that they will ultimately profit and overcome all these costs by selling the crude oil extracted from these oil reserves.
The most common uses of crude-oil is that it is being put to use in the form of gasoline which is the fuel for the aircraft, automobiles, heating oils and also for the generation of the electricity. Apart form this the byproducts that are obtained as a result of the distillation of the oil like paraffin wax, asphalt, sulfur and many others find their use in many chemical and industrial applications worldwide.
There are numerous oil wells and gas wells across the world and several best producing oil wells for sale are listed here. Major companies in the world are focussing on such Oil wells available for sale. Article Source: http://EzineArticles.com/?expert=Andrewz_Boas Article Source: http://EzineArticles.com/5622190
