Kansas Geological Survey, Open File Report 97-14

Digital Petroleum Atlas Annual Report 1996

• Annual Field Production Page provides annual and cumulative field production as data and plots [Since this report was written, the original production page has been replaced by this database query.] (http://magellan.kgs.ku.edu/abyss/public/oil.ogf.IDProdQuery?FieldNumber=6451).
• Regional Setting Page contains regional geologic maps and cross-sections. Figures are small scale to speed loading, but can be expanded to a larger scale by clicking on the figure. ([Page not available--superseded by enhanced DPA Regional Pages])
• General Field Information Page contains general geologic, engineering, drilling and production parameters and practices (http://www.kgs.ku.edu/ DPA/Arroyo/General/arroyoGnrl1.html). Examples include average reservoir porosity, initial reservoir pressure, and typical drilling and logging practices
• Geologic Information Page provides access to a field map and type log. Both the map and type log are graphical user interfaces (http://www.kgs.ku.edu/DPA/Arroyo/Geology/arroyoGeol2.html). Clicking on the different horizonsdisplays structural and isopach maps for the field. Selected cross-sections for the field can be accessed in the same manner. The user can also step through all the maps and cross-sections by using the "Next Page" and "Previous Page" buttons below the field map.
• Geophysical Information Page in Arroyo Field contains synthetic seismic cross sections that were generated from sonic and density well logs (http://www.kgs.ku.edu/DPA/Arroyo/Geophysics/arroyoGeop1.html). Models show the seismic signature for the reservoir sand at selected frequencies.
• Reservoir Information Page provides access to core pictures and core analyses, and petrophysical analysis of each well using the PfEFFER Petrophysical Log Analysis package (http://www.kgs.ku.edu/DPA/Arroyo/ Reservoir/arroyoRese1.html). PfEFFER was used to generate "Pickett Plots" and to determine water saturation, bulk volume water and other petrophysical parameters.
• Well Information Page contains a field map similar to the map on the field homepage (http://www.kgs.ku.edu/DPA/Arroyo/Wells/arroyoWell1.html). However the map is a graphical user interface, and clicking on a well spot produces an individual well page that provides access to all available information (Figure 11, http://www.kgs.ku.edu:80/DPA/Arroyo/Wells/ 20666.html). Access is also provided using searches on the well API number or location (Section, Township and Range). Information for each well in the field includes a scanned image of the original completion report (ACO-1), digital well history including geologic tops, production history, digital electric log data (LAS format), and other data associated with the individual well (e.g., core and petrophysical analyses). All data can be viewed on-line or downloaded to the vistors computer for additional analysis.
