Petroleum is what it is?

"Petroleum is one of the important material that we have. Every day we use oil and gas for a variety of needs. "Oil and gas also provides a major employment worldwide. Ten of thousand people working in the oil and gas industry.

How many of us find activities and goods that use oil and gas?
Yes, almost all activities require energy, oil and gas are energy sources that can be used in various industrial sectors.Formation of Petroleum
 Millions of years ago, the basin or basin in the form of sea life that is filled by marine organisms both animal and microscopic plants, such as plankton. Plankton die-plakton which will sink and accumulate at the bottom of the basin. Over the months since the organism that has died and sunk in the bottom of the basin will be buried by layers of sand and shale deposition. Over millions of years dead organism will be buried deeper and deeper. Karen effect of temperature and pressure so it will decompose dead organisms form a chemical compound called kerogen. This maturation process continues and it will termaturasi kerogen to form hydrocarbons. The perfect ripening process will form the kerogen into oil serdangkan if this maturation process is too long then that is formed is a gas.
"How can we take the oil and gas to the surface of the earth? "
Of the maturation process in the petroleum source rocks (source rock) of oil will migrate up the pressure due to buoyancy, this migration process will fill the reservoir rock is a porous rock. Then be trapped and accumulate as of rock above the redapat rock resevoar insulation or sealing. There are several types of traps or trap petroleum, among other structural trap (anticline) and stratigraphic traps.From oil and gas that is trapped in the reservoir, we can take proper way to drill in position terebut trap. Because of the influence of pressure from within the earth's major oil and gas then shaped liquit will flow out through the drill hole. Petroleum that comes out it still contains a variety of materials such as water and clay, it must be separated before they are sent to refiners. The process of removal of oil and gas from the region found to-oil refinery can be done by flowing through the pipes, but it can also be transferred by way of transported using boats, trucks, trains and other vehicles.
Petroleum System
The concept of petroleum systems, explain the distribution of hydrocarbons in the crust of the earth from the source rocks (source rock) to the reservoir rock.Principal element in the petroleum system are as follows:
- Rock Resources (Source Rock)
- Direction of Migration (Migration Path)
- Rock Reservoir (Reservoir Rock)
In addition to these four basic components, the definition of petroleum systems also involve all the geological processes to create this element. Important factor in the petroleum system include:Organic Richness / type and volume of source rocks (source rock).Temperature and time conditions for source rock maturation (maturation).Time of maturation and expulsion associated with the formation of traps.Adanmya migration path from source to reservoir rocks.Preservation condition terjebaknya trap from time to this day.Relative efficiency of the sealing layer.Petroleum Migration to Antikline
"Where oil can accumulate ...? "
 oil and gas contained in the pore batuandan accumulated in the trap-shaped anticline folds which form layers of limestone. Drilling wells to take oil from this trap. Anticline trap is a trap type most often found in petroleum exploration.
Natural oil seeps:
Occur where the layer due to fault rupture (faulting), hydrocarbons appear in permukaa, raises tar, gas and oil on the surface of the earth.
