As a surging demand of oil and gas all over the world, shale gas and coal-bed methane as uncoventional energy can relieve the energy pressure. The United States, a pioneer in developing shale gas, has a top position in shale gas market. As shale gas has been largely discovered, the improving technology and maturing development and supportive policies stimulate the shale gas production in the United States, which guarantees the energy security, decreases the shale gas price and increases the employment, and changes the traditional framework of the world's gas market. Although there is a dispute in environment impact, the American's developing shale gas as an alternative energy drives a worldwide development.
