Example: 42-501-20130-03-00. The "42" means that this well is located in "State Code" 42 which is Texas. The "501" means that this well is located in "County Code" 501 which is Yoakum County. The "20130" is a "Unique Well Identifier" within the county. The "03" is the "Directional Sidetrack Code" for wells that have been sidetracked. The "00" is the "Event Sequence Code" to indicate how many operations have taken place (i.e. redrill).

This publication was supported by the Alaska Division of Geological & Geophysical Surveys General Fund and in part by the Alaska Energy Inventory State Capital Improvement Projects funding. The authors gratefully acknowledge the individuals, companies, and agencies who have contributed to the priceless materials inventory at the Alaska GMC. Special thanks goes to John Reeder, Alaska GMC Curator (1987-2009), for his dedication and building the foundation of one of the most extensive geologic collections in Alaska.

A geologist's ability to perform modern analyses on these unique samples is paramount for responsible development of the State's vast resources. It is critical that access to and protection of this valuable resource be improved and updated. GMC staff has been acquiring additional inventory details and performing quality control on the information stored in the ever-growing GMC database. Although the main responsibility of the GMC is to preserve and ensure the safety of the physical material stored at the facility, it is equally important to make the material and derived data accessible to the public.

This dataset includes oil and gas well locations and mineral prospect locations related to the materials inventory at the GMC. The oil and gas well locations are provided by the Alaska Oil and Gas Conservation Commission well header <http://doa.alaska.gov/ogc/publicdb.html>. Mineral prospect locations are derived from the Alaska Resource Data File (ARDF), published for individual U.S. Geological Survey 1:250,000 scale quadrangles in Alaska, drilling logs, and the U.S. Geographic Names Information System (GNIS) (USGS, 1981). The dataset also contains previously published data layers from Map of Alaska's coal resources (Merritt and Hawley, 1986), the Alaska Resource Data File (U.S. Geological Survey, 2008), and Historical Mining Regions and Districts of Alaska (Sturmann and Clement, 1993).
The estimated horizontal error of this dataset is +/- 250 meters. The location of some prospects were assigned by information available in Orth, 1971 and may have a coordinate that represents the center of many related boreholes (i.e. Amchitka Island). Mineral prospects of unknown location have been assigned a surface coordinate east of the Alaska GMC on the Earth (61.3493 N, -149.5398 W). Additional research is required to correctly identify these prospects and their true locations. Location accuracy information for Google Earth can be found at <http://earth.google.com/support/bin/static.py?page=guide.cs&guide=22373&topic=23750>.
The Alaska Geologic Materials Center is constantly acquiring additional inventory details and performing quality control on the information for hundreds of thousands of samples -- a process that will take many years to complete. As a result, the GMC strives to find a balance between the public release of samples with more accurate data versus suppressing sample information with partial and/or inaccurate data. The GMC is biased towards greater public access to our store of geologic wealth. Consequently, users of the facility must understand that inventory data may be inadequate or inappropriate for making certain decisions. Always contact the GMC staff to confirm that our released sample inventory will meet your research requirements. GMC staff is also willing, at this contact, to determine if other inventory options might also meet your current needs. Please contact us if you would like to contribute any documented corrections or additions to the GMC inventory data. Contributing maps, drill records, or any other documentation is especially welcome.
Polygon topology is present and clean on the previously published geospatial data layers. Other data are line, point, or annotation data and do not require topologic relationships.
