2000 Digital Petroleum Atlas Annual Report
Since the Digital Petroleum Atlas is an electronic publication, on-line access was provided to the public soon after project inception (January 1996). Use of the DPA products was almost immediate and has grown steadily over the last four plus years (Figure 3). This near real-time transfer of technology and information to the client is one advantage clearly demonstrated by the DPA.
The pages that comprise the DPA make up the bulk of the web site for the Petroleum Research Section (PRS) of the Kansas Geological Survey. Usage statistics show that access to these pages has grown to over 65,000 access "hits" per month (Figure 3). In measuring access "hits" on the PRS site, all access to graphics is removed. This eliminates the multiple counting of access hits that result from multiple figures (buttons, bars, arrows, etc.) on a single web page. In addition, all access from the Kansas Geological Survey subdomain (kgs.ku.edu) is removed. This measurement protocol produces a consistent and conservative measure of external usage. Current usage statistics are collected daily and weekly and are available on the Petroleum Research Section of the Kansas Geological Survey web site (http://www.kgs.ku.edu/usage/past_stats.html).
Each month a detailed usage report is generated for the oil and gas portion of the Kansas Geological Survey web site. The latest report for December 2000 (http://www.kgs.ku.edu/usage/2000/dec_wt/DEFAULT.HTM) provides rough quantitative measures for the Digital Petroleum Atlas. In April, the pages of the Digital Petroleum ranked higher among the most requested pages (Figure 4). Other highly requested pages on the Petroleum Research web server are portals that provide general access to the Digital Petroleum Atlas and other oil and gas information. After the user enters the Digital Petroleum Atlas Home Page or DPA-Kansas Page they split off in any number of directions. The Digital Petroleum Atlas Home Page was also the number 2 most popular entry page and the number 3 most popular exit page. This is interpreted to mean that the DPA is book marked and users jump directly to it. The December statistics also show that the Petroleum Research Web Site and the Digital Petroleum Atlas appealed primarily to companies (.com domain with 58 % of total hits) and networks (.net domain with 39%). The .net domain is interpreted as representing the very small independent and consultant who uses a local or national Internet access provider. Statistics for December 2000 measure the most accessed directories on the Petroleum Research web server. The DPA is the most accessed directory with over 30 percent of the total hits for the site (Figure 5).
Other measures of the impact of the Kansas Digital Petroleum Atlas are unsolicited comments and success stories received by users. A selection of comments is provided in Appendix A.
