How do you find natural gas?

Geologists often use seismic surveys on land and in the ocean to find the right places to drill for natural gas. Seismic surveys create and measure seismic waves in the earth to get information on the geology of rock formations. If the results of those surveys indicate that a site has potential for producing natural gas, an exploratory well is drilled and tested. The results of the test provide information on the quality and quantity of natural gas available in the resource.
