The data collection procedure consisted of georeferencing, collecting, and attributing basins and plays present in publications by the Energy Information Administration, Journal of Petroleum Technology, China University of Geosciences, State geological surveys, Oil and Gas Journal, and other academic, private, and governmental sources. The source information for all features is independently stored in a “Sources” field in the attribute table of both feature classes. This dataset should not be understood to be an all inclusive collection of unconventional formations. It is possible that many formations exist outside of this dataset.
Map images from these sources were extracted and georeferenced using various reference features such as coastlines, political boundaries, water feature convergences, and other reference points. The basin and/or play polygons were then collected employing heads-up digitizing. The scale of these extracted map images varied greatly from map to map. The scales at which these images were georeferenced range from 1:1,000,000 to 1:80,000,000. The attributes for each basin and/or play were recorded by interpreting tabular and textual information in various documentations (not necessarily from the same source which provided the feature geometry). Subsequently, reconciliation between efforts of multiple technicians was conducted by joining and calculating tabular data. Lastly, quality control procedures were conducted to resolve instances in which two or more of our consulted data sources provided features with conflicting basin or play geometry. Examples of these issues included feature overlap, spatial gaps, and other topological issues. Other quality control procedures were conducted in instances in which attributes for given features were incomplete or improperly formatted.
A notable limitation of the data collected in this study is its variation in scale of data capture. Due to the composite nature of this study, the basin and play geometry presented is dependent upon the original capture of the data which varies from feature to feature. Therefore, a field entitled “Georef Scale” was populated for each feature to reflect the extent at which each feature was collected in our digitizing process.
None of the data collected in this study was conducted independently, therefore, WVGISTC, WVU, and the WRI shall not be held accountable for any inaccuracies, discrepancies, incompleteness, or incorrectness of the data presented in this study. Incompleteness of data is explained by the limited amount of documentation as well as time restrictions that hindered the advancement of our procedures. Nevertheless, this dataset provides a broad picture of global unconventionally producing shale basins and plays is a starting point for more detailed research.
