Oil fields are large reservoirs of oil, scattered across few hundred kilometers of arable land. It has an abundance of oil wells, which are used to extract petroleum from below the ground. A typical oil field would appear like a mini city in the middle of a landscape, with scores of wells.

The Oil field investments have risen over the years, with oil’s soaring prices and shrinking supply. This recent surge in oil consumption can be attributed to the industrialization of the third world economies like India and China. As such there is a rush by the oil companies towards oil field investments drilling oil from large accessible fields as it costs them less to extract the oil from the ground.

It is believed that even though the world consumption of crude oil and petroleum is quite high, it has been able to tap only half of the total oil supplies. The investors are eyeing the oil sector to take advantage of the rising prices. Investment in oil can be done by investing in oil companies or by investment in oil related trade funds. The returns from drilling an oil well can be very high and can be expected within few days of starting the investment.
