Detection of oil

Detection of oil
There are three ways to discover oil and gas, namely:
(1) examine the surface of the earth in search of evidence of the presence of oil-bearing formations.
(2) the use of remote sensing to explore the surface of the rock layers below the surface.
(3) the work of measurements in the well.

Each of these methods to study the Earth at three different depths of different lengths ranging between Alanchat and mileage. Begins search for oil search for tank (which is a layer of rock that can detain oil) and the roof is a port stop the vertical movement of the oil and captured in the tank. Even drilling of the well is completed it is difficult to ascertain the presence of oil ... all you can to make sure it is a structure that can contain oil.
 Can modern geology include evidence of oil to be, and sometimes just a few of the leading drilling meters to detect the course of an ancient river, or the way the dunes formed on top of each that.
Geologists draw maps of underground mines and study rocks that have been made to divide the highways, and can fish with this slide represent a small window on what lay beneath them and the great depth.
oil - petroleum
Infrared image of the surface of the earth taken from a satellite or aircraft, and can help us to draw rock formations that may contain oil.
To make sure the presence of hydrocarbons in the field somewhere, you must dig a few wells to help raise Alheidrokarbur to the earth's surface. Long and Drill who digs the ground by metal stick rotates at a rate of 60 or 120 rpm, this drill can dig tens of meters in one day.
 Drill works accompanied by including known as ((drilling unit)), which is a special material poured into the well in order to facilitate the work and in order to avoid sudden flow of oil from the well when the drill up to the class that the oil be limited. Often tends Alheidrokarbur liquid and solid and gaseous about the well automatically.
This what happens in a normal field or in pockets inside the rocks, as can natural gas be carried out abroad. In most cases, Alheidrokarbur heading towards the outside, but rather in some cases, experts have intentionally to create artificial pressure to eject Alheidrokarbur by sending the amount of water or air to the interior.
