Smile The smallest unit of a substance, which still retains the characteristics of that substance, is called a molecule. Molecules can only be divided into atoms - which are different elements. For example, all molecules of water are identical and have the characteristics of water. Two atoms of hydrogen and an atom of oxygen (which made up the molecule) on their own have none of the characteristics of water.

Crude oils are mixtures of many different substances, often difficult to separate, from which various petroleum products are derived, such as: gasoline, kerosene propane, fuel oil, lubricating oil, wax, and asphalt. These substances are mainly compounds of only two elements: carbon (C) and hydrogen (H). They are called, therefore: hydrocarbons.

Refining crude oil involves two kinds of processes to produce the products so essential to modern society. First, there are physical processes which simply refine the crude oil (without altering its molecular structure) into useful products such as lubricating oil or fuel oil. Second, there are chemical or other processes which alter the molecular structure and produce a wide range of products, some of them known by the general term

Troll A platform – the largest structure ever moved by man – to the invisible subsea well heads now operating in the Snøhvit field in the Barents Sea, Norway’s history as a petroleum nation has been written in the pioneering new technologies that have been developed for the harsh environment of the Norwegian Continental Shelf.
