INTRODUCTION
In anticipation of the need for scientific support for policy decisions and in light of the 
decade-old perspective of a previous assessment, the USGS has completed a reassessment 
of the petroleum potential of the ANWR 1002 area. This was a comprehensive study by a 
team of USGS scientists in collaboration on technical issues (but not the assessment) with 
colleagues in other agencies and universities. The study incorporated all available public 
data and included new field and analytic work as well as the reevaluation of all previous 
work.

In keeping with the USGS responsibility for assessing the petroleum potential of all 
onshore and state-water areas of the U.S., the total assessment area was extended offshore 
to the 3-mile boundary between State and Federal jurisdiction. Thus, in addition to the 
Federal lands of the 1002 area, the assessment includes resources associated with adjacent 
State waters and Native lands. Petroleum commodities assessed include crude oil, natural 
gas, and natural gas liquids distributed among 10 petroleum plays. Using a methodology 
similar to that used in previous USGS assessments in the ANWR and the National 
Petroleum Reserve-Alaska, this study estimates the total quantity of in-place and 
technically recoverable oil, gas, and natural gas liquids. Quantities of economically 
recoverable oil are reported as a set of curves (incremental cost functions) which show 
increasing amounts of economically recoverable oil with increasing price. Natural gas is 
considered to be non-economic for at least two decades. 

The amounts of in-place oil estimated for the 1002 area are larger than previous USGS 
estimates. The increase results in large part from improved resolution of reprocessed 
seismic data and geologic analogs provided by recent nearby oil discoveries.

This publication is a two CD-ROM set containing the ANWR Assessment Team’s report 
and supporting data files. This  set contains Portable Document Format (PDF) files, PDF 
viewing software for a variety of systems, a Director movie of panoramas and photos, and 
supporting data files in text and spreadsheet formats. ANWRrpt contains the interactive 
digital report, The Oil and Gas Resource Potential of the Arctic National Wildlife Refuge 
1002 Area, Alaska by the ANWR Assessment Team. ANWRdata contains supporting data 
and Adobe Acrobat Reader software.

INSTRUCTIONS AND DOCUMENTATION FOR OFR 98-34
A. To get started:
Use of this CD-ROM requires the installation of Adobe Acrobat Reader. The software 
for the Image Gallery chapter requires Apple QuickTime 3. The Acrobat Reader 
software is included on the ANWRdata CD-ROM in the acroread directory. Both of 
these packages are available free of charge from Adobe Inc. and Apple Inc. They can 
also be downloaded from the Adobe and Apple web sites. Help files and on-line 
manuals describe the Acrobat Reader software in detail however, the following sections 
will help you get started.

1. Install Acrobat Reader 3 on your hard drive if not already installed.  Adobe Acrobat 
Reader software for Macintosh and Windows systems is included on the ANWRdata 
CD-ROM. Refer to the read me and text files supplied for each type of Acrobat reader 
for specific installation instructions. The read me and text files supplied for each type of 
Acrobat reader files are:

a.   Macintosh:
Acroread/Readme_M.Mac
Acroread/Mac/Reader/Reader/Readme-Reader
Acroread/Mac/Reader/Reader/Readme-Reader V. 3.01
Acroread/Mac/Reader+Search/ Reader/Readme-Reader

b.   Windows:
Acroread/Readme_W.Wri

2. Launch Acrobat Reader and open the ANWR1002.pdf file on the ANWRrpt CD-
ROM.

3. Hints for using Adobe Acrobat
The Acrobat toolbar is located along the top of the Acrobat screen. Most of the icons in 
the tool bar are self-explanatory. The arrow icons move one page at a time. The bar-
arrow icons go to the first or last page in the file. The double-arrow icon allows the user 
to go back and retrace previous views.

Clicking on the red text links to other relevant pages or portions of pages or maps. The 
cursor changes to a pointing finger when it passes over links. For example, the hand 
icon, changes to a pointing finger, which indicates that it is over a link.

The PDF files contain several buttons to facilitate navigation within and between files. 
The left and right pointing red triangles advance the reader to previous and next page in 
the PDF file. The curved left pointing button will take you to the last menu.  The ‘Go 
Back’ button, the left pointing double arrow button should be used to return to the 
previous view.  This is especially useful for returning from references in the text. Several 
clicks on ‘Go Back’ button may be required since each panning or magnification change 
is considered a view by the Acrobat Reader software. The magnification glass icon can be 
accessed in the tool bar at the top of the screen and also along the bottom of the screen to 
zoom in or out . The ‘Thumbnail’ icons on the left side of the screen can be clicked on to 
jump directly to that page. The page that is currently displayed will be highlighted. A box 
on the ‘Thumbnail’ shows which portion of the page is being displayed. Moving this box 
will display a different portion of the page. Changing the size of the box will also change 
the amount of enlargement.

The Acrobat Reader software is described in more detail in the Online Guide that can be 
accessed once you run the Acrobat application.
