What are the conditions to be oil

Called on several oil names such as: oil, black, gold, crude oil, and the oil can be defined as a means to color black tends to greenness, a dense flammable liquid, the oil resides in the upper layer of the earth's crust. Oil is mainly composed primarily of a complex mixture of hydrocarbons, such as alkanes series, which is chemically very precious, and oil differs in terms of its composition and purity and appearance dramatically depending on where the oil has been extracted from him. Oil is used heavily in a number of areas such as: production of electrical energy, and operation of the equipment used in the electrical energy that can be generated in other ways provide the human burning of oil production, the oil is also used in the operation of factories and moving means of transportation, and is also used in chemical products; where it is one of the raw material component of these products, such as fertilizers, pesticides, textiles, rayon, synthetic leather, plastic, medicines, these are one of the benefits and uses of oil and many others, although this indicates anything, it shows on the big importance of oil in our daily lives You can not do without many of the important things in our lives, so it must be maintained because it is one of the important means of energy and used in many, many important things. It produced oil from the ancient geological ages because forests have largely been scattered all over the ground, and aquatic plants and marine plankton and organelles which occurred underground layers, and after millions of years with the increase in pressure it turned into oil. Stages and conditions of the oil be the first phase stage configuration; where they are at this stage of oil composition and must have the following: organic matter, which must be present in high concentrations in the rock layers are called these rocks are the source rocks. The presence of heat. The existence of proper pressure in large depths. This is phase three of the conditions Banagatha be oil. The second phase of migration stage: the stage where the oil migrates from the place you are from any of the high source rocks Alsguet to other areas less pressure, which is made by two factors: the pressure difference: It is responsible for moving oil power. Cracks and fractures in the rock to allow the passage of oil. The third phase of assembly stage: the final stage, which works to collect oil in large quantities, so it must be the presence of the oil trap system, which works to prevent the continuation of the oil migration
