The global distribution of basin-centered gas accumulations (BCGAs) is poorly known, and knowledge of the stratigraphic distribution of BCGAs is incomplete. Even in North America, where most of the exploration activity for BCGAs has occurred, the geographic distribution is not well known. [[:file:BasinCenteredGasFig13.jpg|Figure 1]] shows the locations of known and suspected BCGAs in the United States. A tabulation of these areas, as well as areas outside North America, is shown in Table 1. The geographic distribution of BCGAs is probably best known in the Rocky Mountain region, where a considerable amount of research has occurred.

Worldwide, there are only a few references available alluding to the presence of BCGAs (Table 1). Many more areas undoubtedly contain BCGAs, but because of the poor understanding of the concepts of BCGSs in countries outside North America, the global distribution of BCGAs is poorly known. For example, in North America, many Rocky Mountain basins contain direct BCGAs. By analogy with Rocky Mountain basins, it is likely that many of the Andean foreland basins of South America also contain BCGAs. Several of the basins in the Middle East and North Africa probably contain indirect BCGAs similar to those in Jordan and Algeria.
