1368712539 General View of Geophysical Methods Used in Prospecting For Oil

Petroleum is naturally liquid form, which is found underground. It is a mixture of hydrocarbons when it is affected by the atmospheric condtions. It may seen dark, yellow, green, khaki, brown, dark brown and black as a chemical appearance. Petroleum, formed as a result of a long geological processes of complex physical and chemical functions. It is clear that, the main objective of experts is to determine qil traps in prospecting for oil. The first phase of prospecting for oil is to determine the appropriate geological places that consist hydrocarbons. In this stage prographs taken from air and space are frequently used. Prospecting for oil area must be formed from sedimentary (sedimentary-sedimentary) rocks. Also source rock must have an overplay in order to cover the oil and to accumulate the oil. By this way it prevents to vanish the oil. This study focuses on the geophysical methods used in prospecting for oil. Geophysics measure the various physical characteristics of the earth's crust. Especially, seismic gravity and magnetic geophysical surveys are basicly used in prospecting for oil. Seismic which is the most widely used method for finding underground hydrocarbon deposits, record the sounds waves of main sources. These sound waves reflects and come back to earth. These waves are recorded by geophone .They are also processed and interpreted by computer programsin order to identify the possible locations of petroleum deposits.
