Abstract: This is a blob map of the general areas for shale plays in the US as of 5-6-2011. The polygons are constructed in a variety of ways which cannot be consistent due to the variety of data available and the maturity of each shale play. For example, some are outlines around active drilled areas, others are the USGS interpretation of the assesment unit, etc. See the attribute "References" for the literature source for each outline.
