Locations - Oil & Gas wells - download database

  The following database has well locations including lat/longs (which are not in the on-line database) for wells in Michigan. 
  The download is a zipped file of a Microsoft Access 2000 database.

How coordinates are determined:
  In the Well Coordinates table is there a Source_Loc field for both the surface and bottom hole locations.  The code represents how the lat/longs were determined.
  The codes are:
   C = Calculated by computer using the footages from the section lines.
   G = GPSed by field staff. 
   M = Manually taken by plotting on a map.  In these cases the computer couldn't calculate and there was no GPS reading. 

The coordinate systems used:
X-Y data is in NAD 1983 Michigan GeoRef meters
Lat-long is NAD 1983

Abbreviations and explanation
Wh_ = well head -prefix used in column headings for surface locations
BH_ = bottom hole - prefix used on column headings for bottom of the hole
Slant = can be V (vertical), D (directional), or H (Horizontal)
     for Vertical wells, the surface and bottom hole locations should be the same
Twpn = Township Number
Twpd = Township Direction - combine with Twpn to get the Town as 27N
RngN = Range Number
RngD = Range Direction - combine with RngN to get the Range as 6W

What's NOT included.
This download doesn't include well locations for permitted oil and gas wells that are confidential or wells with permits after the last update. 

Formation codes

Well Location download  
About 4 MB, check the date in the file name to find when it was last updated.  This zipped (compressed) file must be saved to your own computer (it will not open from the server) and unzipped before it can be opened with Microsoft Access.  (If you do not have Microsoft Access, use the online database.)  . 
The download is on an ftp server at: ftp://ftp.deq.state.mi.us/deq-outgoing/ 
Copy and paste the Username and password if you need to log in:
Username= deq-public-ftp
password= Jumbl355#
Look in the Well_Locations folder.

If you can't connect, either a pop-up blocker or a company firewall is stopping it, contact your IT person to fix this, or take a laptop to a nearby wi-fi hot spot and you'll be able to connect.

After two weeks, the file may be deleted automatically.  Contact us to have it restored..

(Important:  Copy the file to your own computer before trying to open it.  It will not open from the ftp server.)

County maps with wells plotted
These maps are in .pdf format.  To see the well information (permit number etc.) use the zoom in tool in Adobe Acrobat.  The maps are updated weekly.

Drilling Unit maps
Maps in .pdf format are available for most of the northern lower Michigan counties and three southern Michigan counties.  This ongoing project will eventually provide maps for all of lower Michigan.
