Oil World is quite possibly one of the most amazing oil and gas sites on the web. It is updated TWICE daily, and includes information on EVERYTHING in the oil and gas industry. The webmaster has been operating this site since 1996, and they have really done an excellent job providing coverage on almost every new development affecting the oil and gas industry since then. It’s not a technical resource, although they do provide links to other technical resources on the Internet. It is primarily a news service, but you get news on every technical sector in the oil and gas industry. If you don’t currently read this site daily, you are LOSING MONEY! They even offer daily fax services of featured highlights or energy quotes.
