The global oil and gas industry is a unique and sophisticated industry. In looking at some of its interesting characteristics, state-owned companies dominate exploration and production, referred to as "upstream services," while publicly owned companies dominate the refining and marketing aspects of the industry, or "down stream services."1

Estimating the size of the world oil and gas industry is a difficult task. For instance, the state-owned companies do not issue stock, therefore cannot be valued based on market capitalization.2 In addition, variations in accounting standards and the lack of transparency with many state-owned firms, make it difficult to estimate the industry's actual revenues and earnings. Estimating the size of the oil and gas industry is much easier when evaluating the publicly owned firms.

Oil and gas company rankings can be found in a number of different sources, which include: Standard & Poor's Industry Survey "Oil & Gas: Production & Marketing" (March 2013):

In doing company research, one of the first sources to check for information is the company itself. Company web pages can be a wealth of information. In particular, the Investor Relations and Press Release/News sections. The Investor Relations section is a good source for all of the financial filings made to the government regulatory bodies. While these filings are usually located on the company web pages, this information can be obtained by accessing the filings through the Securities & Exchange Commission (SEC), specifically the SEC's EDGAR Database.

There are several filings to which one should pay particular attention.

The first is the 10K or annual filing. Along with all of the annual financial information, this filing also has sections that can provide information on the company operations and sometimes insight on the industry itself. Item 1 is the Business section, and it contains information on various business lines/segments as well as sometimes information on strategy, marketing, and competition. Item 7 is the Management Discussion & Analysis section and it contains specific notes to various things reported in the 10K. This section is often where more segment information as well as geographical segment information can be found.
The second filing is the 10Q which is a quarterly filing. It is not nearly as in-depth as the 10K and is primarily used to update the financial data.
Third is the Proxy statement which is usually published around the time as the 10K, and contains all of the executive and executive compensation issues.
The last is the Annual Report sent out to shareholders. Some company's annual reports and 10Ks contain roughly the same information but the annual report is presented in ways that people without technical expertise can understand.

There are also many other databases that contain company and industry data. Many of these databases require a subscription and can be quite expensive. Some of the many databases available include: Hoovers, Mergent, Standard & Poor's NetAdvantage, Gale's Business & Company Resource, and Dow Jones Factiva. Local public or university libraries are good places to access these and other resources. These and other resources included in this section, are intended to assist in researching this very complex, fascinating and critically important global industry.
