You can use Latitude and longitude to find a well or location.  You can also get the latitude and longitude for any place in Michigan. 

If you know one or more of the well attributes (Permit Number, API Number, Well Name, Company, Field etc.) you can use that information to find a well and its records and data.  You can use a partial name which you can redefine if you get too many responses.

Ever want to make your own geologic map?  Here are instructions on how to do just that.  The example is a starting point.  You can easily change what is displayed and the area covered to suite your needs.

The GeoWebFace provides web and FTP access to over 150 GB of digital files and information from the OOGM Oil and Gas database.

System Requirements

In order to use the GeoWebFace you need access to the Internet.  The GeoWebFace was designed and tested using Microsoft Internet Explorer 8.  Other contemporary web browsers can be used.  However, some screens may look differently and some procedures may need to be modified.  The speed at which maps are drawn or refreshed is in part a function of the speed of your internet connection and the computer equipment you are using.  Some selections, like a number of oil and gas wells, may take a moment or two to gather the data and display it.  The speed of FTP transfers is likewise a function of system resources and configuration as well as the number of users accessing the server.
