Crude oil is obtained by drilling down into the ground to an oil well. The oil is then pumped out of the ground and put into barrels. The barrels of oil are then sent to a plant where it is processed into different products for consumer use.
you extract them by drilling wells
The answer is oil.
Scientists can use sonar and seismic studies to test an area for oil. It is not always certain, however. To really find out if an area is rich in oil, drilling must occur.
At present, drilling for oil is prohibited until 2048. See Wikipedia link. Second, there has been some drilling in the 1970's offshore in the Ross Sea, but only traces of gas were found. It will be hard to justify spending money to explore for oil, as the cost of drilling and producing is very high. So the ban on exploration may continue after 2048. See second link.

Drilling for natural gas is similar to drilling for oil, but gas must be liquefied before it can be shipped.
