The mapped oil and gas field boundary outlines were created by the Reserves and Production Division, Office of Oil and Gas, Energy Information Administration pursuant to studies required by Section 604 of the Energy Policy and Conservation ActAmendments of 2000 (P.L. 106-469). The boundaries are not informed by subsurface structural information. The data andmethods used in their creation are detailed in a report, "ScientificInventory of Onshore Federal Lands' Oil and Gas Resources and Reserves and the Extent and Nature of Restrictions to Their Development", prepared by the US Departments of Interior, Agriculture and Energy.Bottom-hole well locations were not available digitally for directionaland horizontal wells, therefore the field boundaries for fields withmany of those well types may be conservative.Onshore elevation shaded relief from ESRI.Map created May 2008; projection is UTM-10, NAD-27.Authors: Samuel H.
