Natural Gas | National Geographic Society

Natural gas is most commonly extracted by drilling vertically from the Earth's surface. From a single vertical drill, the well is limited to the gas reserves it encounters. Hydraulic fracturing, horizontal drilling, and acidizing are processes to expand the amount of gas that a well can access, and thus increase its productivity.
