ray-

I've  seen thousands of logs and have spent many long hours in logging units watching logs being obtained and assisting with the quality control process, as well as sweating it out with the logging/drilling crews when the tools were stubborn in going to the bottom of the hole(s).

 

I've also had "tool lost in well" invoices personally land on my desk. The first one for an induction log tool that broke in two in a deep, high pressure Texas Panhandle well in 1984 for $10,000 and the second for $1.7 million for a pressure/fluid sampling tool irretrievably lost in a gas well offshore Trinidad, West Indies in 2008.

 

I'm not sure where you may find well logs online, but many state geological survey websites will only let an operator keep log data confidential for a finite and relatively short period of time. Regardless of where the log data are obtained, to the untrained eye they will appear as a only bunch of squiggly lines.

I have found the folks at the Ohio Geological Survey offices in Columbus to be very helpful with public access to the information they have on file.  Due to the stage at which the Utica play is in, they may not have all the information you are looking for such as the mud logs, but I have occasionally seen this type of data in the files for some wells.  The Division of Oil Gas and Minerals of the Ohio Department of Natural Resources has a well database that is searchable online that would contain the casing and cementing information for wells as well as the formation top elevations.  Copies of well logs are also available for some wells and may be ordered online from the Ohio Geological Survey.
