The U.S. oil and natural gas industry provides energy security and economic benefits to our nation, supporting more than 9.8 million jobs and contributing $1.2 trillion in added value to the economy. See information by individual state (interactive map).
America's oil and natural gas industry supplies tens of millions of dollars a day to the U.S. Treasury in the form of income taxes, rents, royalties and other fees. That adds up to more than $30 billion a year.

There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs - hence the name fossil fuels. The age they were formed is called the Carboniferous Period. It was part of the Paleozoic Era. "Carboniferous" gets its name from carbon, the basic element in coal and other fossil fuels.
Oil and natural gas together make petroleum. Petroleum, which is Latin for "rock oil," is a fossil fuel, meaning it was made naturally from decaying prehistoric plant and animal remains. It is a mixture of hundreds of different hydrocarbons molecules containing hydrogen and carbon that exist sometimes as a liquid (crude oil) and sometimes as a vapor (natural gas).
For more than 75 years, the American Petroleum Institute (API) has led the development of petroleum and petrochemical equipment and operating standards. Currently, API maintains approximately 500 standards and recommended practices covering all segments of the oil and gas industry.

API HF1, Hydraulic Fracturing Operations-Well Construction and Integrity Guidelines, First Edition/October 2009
This document provides guidance and industry recommended practices for well construction and integrity for wells that will be hydraulically fractured. It includes information on protecting groundwater and the environment, well design and construction, hydraulic fracturing, and monitoring and testing.
API HF2, Water Management Associated with Hydraulic Fracturing, First Edition/June 2010 This document explains current industry best practices to minimize environmental and societal impacts associated with the acquisition, use, management, treatment, and disposal of water and other fluids associated with the process of hydraulic fracturing.
