These data were compiled from previously published and unpublished sources and were prepared for use in the 2002 U.S. Geological Survey petroleum assessment of Central Alaska, Yukon Flats region. Indications of petroleum are described as oil or gas shows in wells, oil or gas seeps, or outcrops of oil shale or oil-bearing rock and include confirmed and unconfirmed reports. The scale of the source map limits the spatial resolution (scale) of the database to 1:2,500,000 or smaller. Purpose: This database and accompanying text file describe historical and modern occurrences of petroleum in wells and natural seeps in Central Alaska at a regional (1:2,500,000) scale. This database was developed for the US Geological Survey's petroleum assessment of Central Alaska. The report is intended to provide information on historical and modern indications of petroleum within the Central Alaska Province boundaries. Supplemental_Information: This report was compiled and digitized from previously published and unpublished sources. This coverage was compiled in ArcInfo, a commercial Geographic Information System produced by ESRI (Environmental Systems Research Institute, Redlands, California), version 8.2.0. The files are coverage (ArcInfo vector data) format. Coverages are stored in uncompressed ARC export format (ArcInfo version 8.2.0). ArcInfo export files (files with .e00 extensions) can be converted into ArcInfo coverages in ArcInfo and can be read by some other Geographic Information Systems, such as MapInfo and ESRI's ArcView (limited versions of this software are available for free from ESRI's web site: ). The primary source of information on seeps and older wells is Miller and others (1959). Additional information on seeps and wells was acquired form the published literature, public records available at the Alaska Oil and Gas Conservation Commission and the Alaska Geologic Materials Center, and unpublished documents provided by companies and individuals.

Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:2,500,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:2,500,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database Point_of_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Richard Stanley Contact_Organization: United States Geological Survey Contact_Position: Senior Scientist Contact_Facsimile_Telephone: 650-329-4975 Contact_Electronic_Mail_Address: rstanley@usgs.gov Hours_of_Service: Business hours PST Data_Set_Credit: Data compiled by Rick Stanley and Sandra Troutman, USGS Menlo Park, CA Security_Information: Security_Classification_System: none Security_Classification: Unclassified Security_Handling_Description: none Native_Data_Set_Environment: Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 1; ESRI ArcCatalog 8.2.0.700 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The level of accuracy of individual data points is included in the database and is discussed in the text accompanying the coverage. Completeness_Report: This coverage is intended to describe historical reports of indications of petroleum occurring within the central Alaska province boundary and does not include indications of petroleum within the state of Alaska outside this boundary. This information has been solicited and collected from available sources but may not represent all such occurrences. Updates will be made to the database as needed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Positional accuracy of data varies depending on the source of the information. Points attributed to Miller, et al, (1959) include inherent errors in accuracy associated with determining locations from third-party sources and are discussed in the original text. Points from Miller, et al (1951) were digitized from the original paper map at a scale of 1:2,500,000 georeferenced to a state of Alaska coverage with an RMS error of .002 digitizer inches. At this scale, individual points are approximately 1mm in diameter and therefore have a positional accuracy of .5mm at 1:2,500,000, or within 1.25 km on the ground. The general positional accuracy of onshore wells was taken from public record survey data maintained by the Alaska Oil and Gas Conservation Commission and is accurate to within 10 meters on the ground. Locations of offshore wells are from survey data maintained by the Minerals Management Service. This survey data was plotted onto 1:63,360 scale maps in order to determine latitude and longitude. This is the largest scale map available for most of Alaska, with the exception of population centers. These data locations are deemed to be accurate to within 1km on the ground. Locations of all other modern indications of petroleum are taken from references as noted.

Process_Step: Process_Description: The location information for points attributed to Miller, et al, 1959, was digitized from a stable, original, paper map at a 1:2,500,000 scale. This map was scanned on a large-scale, flatbed scanner with a resolution of 600 dots per inch. The scanned image was georeferenced interactively with ArcInfo and rectified with a first order polynomial transformation. The data points were digitized interactively by hand.
