Atlas Navigation

Navigation among the Digital Petroleum Atlas web pages is provided by a suite of standardized buttons that provide hypertext links or through search engines. The navigational tools permit the user to move through the DPA in a more or less linear path, similar to a traditional book, or to skip rapidly among related subjects and scales.

Navigational Buttons

As with all World-Wide-Web pages, text that is blue and underlined provides links to other pages. Some links are to other pages in the DPA, some are to other pages on the world-wide-web server at the Kansas Geological Survey, and a few may lead to servers outside the Kansas Geological Survey. At the top and bottom of DPA web pages is a standardized suite of navigational buttons that provide hypertext links to various critical DPA web pages. The top navigation bar should appear in red (Figure 12). It contains the following set of navigation buttons to move the user among the major DPA components and to other petroleum related research units at the University of Kansas.

DPA Home: Link to the homepage for the Digital Petroleum Atlas Project (http://www.kgs.ku.edu/DPA/dpaHome.html). The Homepage for the Digital Petroleum Atlas Project contains an additional navigation button in blue that provides a direct link to the US Department of Energy homepage (http://www.doe.gov/).

• Kansas: Link to the homepage for the Kansas section for the Digital Petroleum Atlas (http://www.kgs.ku.edu/DPA/dpaKansas.html).
• KGS: Link to the homepage for the Kansas Geological Survey (http://www.kgs.ku.edu/kgs.html).
• PTTC: Link to the homepage for the Northern Mid-continent Resource Center of the Petroleum Technology Transfer Council http://www.nmcpttc.org/)
• Help ? : Link to a help page that provides an explanation of the structure and navigation tools used by the DPA project (http://www.kgs.ku.edu/DPA/Help/dpaHelp.html).
• Site Map: Link to an interactive map of the structure of the DPA project (http://www.kgs.ku.edu/DPA/dpaMap.html).
  

 A navigation bar located on each field-level homepage provide links to standardized topical areas (figures 10, and 13a). The topical areas covered include:

• Regional Setting: Provides regional-scale maps covering the geology and production.
• General Information: Basic geologic, geophysical, fluid, engineering, completion, and production data and techniques at the field-scale.
• Geological Information: Access to geologic field maps and cross-sections though a type log graphical user interface. Clicking on selected horizon provides access to multiple maps at different stratigraphic levels. Access is also provided to structural and stratigraphic cross-sections.
• Geophysical Information: Access reflection seismic and other geophysical data (e.g., gravity and magnetics).
• Reservoir Information: Contains reservoir engineering, petrophysical and geologic information.
• Well Information: Provides access to information on a single wellbore (Figure 11). Access is through an interactive map (click on a well symbol) or search criteria (Figure 13C, API number or location). Data includes raster image of original completion report (ACO-1 in Kansas), digital "scout ticket" data, production data in graphical and digital formats, and digital log data. Digital log data is in LAS format and can be read by various log readers. Also include are any core analyses or interpreted material associated with that particular well.
  

In addition to the navigation bar for topical areas, buttons on the bottom of selected regional, county and field homepages provide the user the ability to move stepwise through the material. A set of "next page / previous page" buttons provides a more-or-less linear book-like approach to navigating through DPA material (Figure 13b).

Interactive Image Maps

Clickable interactive image maps and figures occur throughout the DPA (Figure 14). These graphical user interfaces are surrounded by a blue box and provide active links to custom maps and plots and to access additional DPA pages. Examples include the interactive map on the Well Information Page under each field study (Figure 14a). Clicking on a well spot on this image map provides access to the well page for that particular well (e.g., Figure 11). Another example is the interactive stratigraphic column on each County Page (figures 9, and 14b). By clicking on each active stratigraphic horizon, the column provides access to geologic and geophysical maps. Similar interactive image maps and figures occur throughout the DPA and provide links to maps, cross-sections, production plots, figures, and a wide variety of information and interpretative material.

Fields and wells in the DPA can be searched by geographic location (Section-Township-Range), name (API number or field name) and in the case of fields by a flexible search routine that incorporates production and geologic parameters. The search for wells and fields can be accessed through a navigation bar the appears on the Kansas DPA Homepage (figures 13c and 6, http://www.kgs.ku.edu/DPA/dpaKansas.html). Similar buttons to access search programs are available on the county and field pages.

Several search routines written in C permit search by county, section-township-range, or API number of individual well data (e.g., logs, completion reports, production, etc.). All wells used in the DPA are accessible through on-line search routines. Fields in Kansas can be retrieved using a similar set of input panels and C programs (Figure 15, [replaced by http://www.kgs.ku.edu/Magellan/Field/index.html]). Parameters such as geographic location, producing horizon, discovery date, cumulative production, reservoir lithology, trap type, etc., can be used to sort and search the 6,000+/- Kansas oil and gas fields. Field studies that are part of the DPA are returned as active links that can be used to access additional information.

The search panel and programs are the basis of searches at the play, field, reservoir and well levels, and provides the engine for flexible searching based on user selected geologic and production criteria through the thousands of fields, reservoirs or wells.

While a researcher new to Kansas may find the maps and charts are the most efficient way to become familiar with the data available on-line, the experienced user can use the search engines to locate answers to specific production and exploration questions. Work in progress will replace the existing C programs with powerful database software (ORACLE). Replacing the custom-written programs will provide greater flexibility to the user and reduce maintenance of the DPA.
