How do you get oil?
Occasionally underground oil seeps to the surface. Then it is
easy to find. However, most oil is buried underground.We have to
drill through the rock to get it. Early rigs could only work on
land. However, we can now use oil platforms to get oil out from
under the sea bed.These geologists are looking for oil. They use
charts of rock layers called seismic surveys.When they find
places that might hold oil, they send out a drilling team to test
