INTRODUCTION This report presents a division of the world into 937 geologic provinces and identifies those that the United States Geological Survey (USGS) plans to assess for petroleum resources. The selection of geologic provinces to be assessed was based on a ranking of known petroleum volumes in terms of barrels of oil equivalent (BOE). The World Energy Project of the USGS is undertaking an assessment of the undiscovered oil and gas resources of the world using new assessment methods, new databases, and a total petroleum system approach. The identification and ranking of geologic provinces comprise the first of a three step assessment process. The second step involves identifying and mapping total petroleum systems within each province. The third step is the assessment of the total petroleum systems. This report presents the results of the first step. Seventy-six provinces were defined as priority provinces. These provinces together represent 95% of the world's known petroleum volume exclusive of the United States (U.S.), are here called priority provinces, and comprise the main group of provinces that will be assessed. In addition, certain other provinces in the world will be assessed for a variety of political, technical, or geographic reasons and are identified as boutique provinces. In this report, we define regions and geologic provinces, allocate known petroleum volume of fields to those provinces, and rank the provinces according to the known petroleum volume allocated. We identify priority and boutique provinces for assessment. In addition, we discuss the ranking of provinces and the relation of the ranking to potential reserve growth and undiscovered resources.

INSTRUCTIONS AND DOCUMENTATION FOR OFR 97-463 A. Contents Files on this CD-ROM include : 1. WEPROV.PDFÑ Portable Document File (Acrobat) This file combines over 200 pages of text, tables, appendices, and plates in an Adobe Portable Document File, which is readable by means of the freeware program, Acrobat Reader 3, that is included on the CDÐROM. Instructions below describe how to install Acrobat, as well as launch, view, navigate, and search the file. 2. Various installation instructions and files for Adobe Acrobat reader, see section V. below. V. ACROBAT READER INSTALLATION A. Installation procedures vary slightly among the five platforms listed below, but, generally, the procedure is as follows: 1. Copy the WEPROV.PDF file to your hard drive if appromimately 8Mb is available. The file can be accessed from the CD-ROM, however, response will be greatly improved if the file is copied to a disk drive. 2. Install Acrobat Reader 3 on your hard drive if not already installed. 3. Launch Acrobat Reader and then open the WEPROV.PDF file. Refer to the read me and text files supplied for each type of Acrobat reader for specific installation instructions. These files are: B. Macintosh: ACROREAD/README_M.MAC ACROREAD/MAC/Reader/Reader/ReadMe-Reader ACROREAD/MAC/Reader/Reader+Search/ReadMe-Reader C. Windows: ACROREAD/WIN/READER/16BIT/README.TXT ACROREAD/WIN/READER/ 32BIT/README.TXT ACROREAD/WIN/RDR_SRCH/16BIT/README.TXT ACROREAD/WIN/RDR_SRCH/32BIT/README.TXT D. UNIX systems: ACROREAD/UNIX/READER/INSTGUID.TXT ACROREAD/UNIX/READER/LICREAD.TXT ACROREAD/UNIX/RDR_SRCH/INSTGUID.TXT ACROREAD/UNIX/RDR_SRCH/LICREAD.TXT VI. HINTS FOR USING 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 WEPROV.PDF file contains several buttons to facilitate navigation within the file. 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 view and is the same as selecting ÒGo BackÓ from the ÒViewÓ menu. 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 ÒThumbnailÓ 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 ÒThumbnailÓ 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.
