MAGANIZEEXTRACTION OF PETROLEUM

The extraction of petroleum is the process by which usable petroleum is drawn out from beneath the earth's surface.

LOCATING OIL DEPOSITSGeologists use seismic surveys to search for geological structures that may form oil reservoirs. The "classic" method includes making an underground explosion nearby and observing the seismic response that provides information about the geological structures under the ground.

When it comes to finding oil, geologists are the ones responsible. Geologists use their knowledge of rock formations in order to find the right conditions for an oil trap. In years past, geologists were forced to interpret surface features, surface rock, soil types, and occasionally core samples obtained by shallow drilling in order to predict the location of oil deposits.

DRILLING AND EXTRACTIONOnce a potential oil deposit is located, a development plan is created. A development plan considers whether the oil deposit is more liquid or solid and how economically feasible it will be to extract oil from the location. It was once the case that test drilling was a common practice. However, due to the cost of drilling a single well, particularly in deep water, and improved techniques for assessment, test wells are seldom drilled now. If a well is drilled, it is because the deposit is almost guaranteed to produce oil. The cost of a single deep water oil or gas well can cost in excess of 50 million USD just to drill.

For a certain pressure step in the reservoir it is necessary that the natural energy that pushes the fluids is no longer sufficient, it is at this moment when the use of an artificial mechanism is used to continue extracting hydrocarbons, in this case said mechanism is the mecanical pumping.
