Selected Data for Eleven Wildcat Wells in the National Petroleum Reserve in Alaska

Disc Information

This CD-ROM makes available selected data sets from eleven wildcat wells in the National Petroleum Reserve in Alaska (NPRA). The CD-ROM is designed strictly as a "data archive" with a simple HTML interface to aid in navigating the disc.

The CD-ROM was written to the ISO 9660 standard and was produced to work in the greatest number of environments. The HTML was written as generically as possible in order to work with as many browsers and operating systems as possible. The Adobe Acrobat PDF files were kept below 4 megabytes (MB's) in order to avoid the problem some browsers have with PDF files greater than that size. Further, the smaller file sizes facilitate serving this disc over the Internet.

The following data types are provided for each well:

• Photographs of Cores
• Depths to Selected Stratigraphic Horizons
• Geological and Drilling Reports
• LAS-Format Core-Gamma Ray Data
• LAS-Format Borehole-log Data
• Permeability, Porosity, and Grain Density Data

For best viewing, all ASCII files should be viewed using a fixed size font, such as Courier.
