Eastern Ohio well map via Google Earth

Attached map shows well locations and well types for several eastern Ohio counties. The map index allows you to select different counties, townships and well types; you can zoom in and out to change your viewing altitude; you can get well information by positioning you mouse over the well pin; newer wells (after 6/10) are identified with red pins, larger red pins identify likely Utica wells.

 

To view this map you need the latest version Google Earth viewer.  The free viewer can be downloaded at: http://www.google.com/earth  Google limits the number of concurrent data points/well locations - if you open more than three counties at once some data points may disappear.

 

The map shows some interesting patterns.  The high density green pin areas are likely good  areas for Clinton wells... will these be Goldilocks areas for the Utica wells?   Most of the black hole zones are likely due to poor producing wells and most of the current Utica wells are located in these areas...  do the geologist see these areas as good areas or is it simply that they were available for drilling?

 

I’d would be very interested in hearing back what others observe, theorize from the maps or know from experience or hear-say.

Ohio Geological Survey Oil & Gas Interactive web map shows 4 core sample holdings for Morgan County.   Again, why so few?

This is what ODNR site says:

"The cores were drilled by private citizens, company representatives, government officials, and researchers, who then donated the core samples (and often core descriptions) to the Division of Geological Survey"

I guess only 4 samples where donated.  How much information do they give you on the paper map?

Core ID number and DGS ID (4-number) is all the info.

The DGS collection had 845 borings and core descriptions but not all cores.  Publication date 07/2008, but it looks like the map  was compiled in 1989.

Geez...there ought to be a law: "The state (and science) get the core  for every hole drilled".

Look at how many core samples Ohio donated to the Federal Research Center:

The Federal Core Research has 1.7 million feet of core for the country.

I don't think it will help you but I mapped 3 of the 4 core records in Morgan Co.  The forth had no data.  The cores only go down about 900 feet.  But I found them interesting.  You can click on each core record marker and then click on the PDF file of the actual record.

Great job, Philip.  Thank you.

I see that all three wells were drilled by DNR for coal exploration.

This must mean that there is no PUBLIC information on the location of  Marcellus shale for Morgan County.  Of course, I may be jumping to conclusions.

And then, I infer that this is why there is drilling all over Noble County and little or none in Morgan right now.

Any other theories??

There is a great deal of data that only the gas companies have. The drilling is just getting started.  If the Anadarko wells in Noble Co produce.  You will see them move into Morgan.

For you serious geology geeks, here is a Google Earth map layer of the Structure Contour Map On The Precambian Unconformity Surface in Ohio.  The map is based the data from 207 oil and gas wells in Ohio. After you open the file in Google Earth you can click on it's properties to control the opacity and there is a link to the 19 page report that explains the map.

This forum should have a "Like" button ... similar to Facebook's.

Here is a map layer that has the Core Records for Guernsey Co. Most of them are mapping the coal veins. The pink place marker is a  deeper Core Analysis that shows some oil.  You can click on the marker for a link to the report.

You are right, I checked ODNR server http://www.dnr.state.oh.us/Website/Geosurvey/oilgas/viewer.htm and I get the same error message.  The server seems to crash regularly.  Try again tomorrow, maybe they will have rebooted it.  Unless they are on a long holiday weekend.  I have attached the pdf of the core analysis for the pink marker closest to the Anadarko well.  It shows some oil present between 4791' and  4811'.  The Anadarko well is permitted to 6800'.  I wonder if there is a correlation between oil in a higher strata and and oil trapped lower down in the shale layers?

Is there an impervious layer between the lower and higher layer?
