Arizona Oil and Gas Well Viewer|
October 3, 2013 | Arizona Geological Survey / Oil and Gas Conservation Commission
The state of Arizona has developed an interactive viewer that allows anyone to obtain information about oil and natural gas wells. The digitizing effort focused on deep wells across northeastern Arizona including wells that penetrated Precambrian basement and wells in the oil and gas fields with the highest cumulative production.
The AZGS developed a user-friendly web application to make the digitized well data available online to facilitate the widest possible access and use of the data. The search and download map includes more than 1100 well folders, 2500 scanned tiff images of well logs, and the newly digitized LAS data. The search and download map is accessed under the Online Data tab on the State of Arizona Oil and Gas Conservation Commission website. A total of 275 logs from 120 wells for a total of about 962 curves were digitized into LAS format through September 30, 2103.

Natural Hazard Viewer for Arizona|
September 24, 2013 | Arizona Geological Survey
The interactive Natural Hazard Viewer focuses on four hazards common to Arizona — geologic faults and earthquakes, earth fissures, floods and wildfire. Each hazard is described in detail and displayed as a layer on a map. Moreover, the natural hazard information is dynamic; site updates will occur as new or revised hazard data becomes available.
Editor’s Comment: Every state geological survey should have one of these!
Mapping the Pirate Fault|
September 17, 2013 | Arizona Geological Survey
“The 25 km accessible trace of the Pirate fault has been mapped to locate and describe those erosionally exhumed remnants of the fault that together provide a basis for structural reconstruction of this nominally Basin-Range tectonic feature. The fault forms the western boundary of the Santa Catalina Mountains in southeastern Arizona, where it separates the uplifted Santa Catalina structural block on the east from the down-dropped, alluvial Cañada del Oro basin on the west.” Quoted from the Arizona Geological Survey publication release.
