Stringent standards and operating procedures for natural gas drilling, based upon decades of experience, protect citizens and the environment.  They are enforced by the drilling companies and the government through strict regulations and oversight. 

The American Petroleum Institute (API) is a trade association representing 400 member companies across the oil and natural gas industry.  For more than 85 years, API, in conjunction with its member companies, has developed and refined engineering standards and practices for all aspects of oil and natural gas production.  Many of these standards have been adopted as references for industry performance, and incorporated into state and federal regulations.  These standards, considered industry practice, cover all aspects of Marcellus Shale production, including site preparation, drilling, well construction, well integrity, water use management and surface environmental considerations.
Companies that are producing natural gas from the Marcellus Shale adhere to these strict standards when planning for and operating their wells.  Many of these companies are also the ones who developed the standards, and have been using them in production for years, if not decades.  Since hydraulic fracturing began in the 1940's, more than 1 million wells have been drilled, and in Pennsylvania, alone, more than 700 wells have been put into production using this technology.  The companies that continue to follow these strict standards and regulations, will protect the safety and health of Pennsylvania citizens and the environment.  API and its member companies also continually monitor and update these standards to ensure operational safety and efficiency.
