As of June, 2009, the Office of Geological Survey has converted 57,810 paper wire-line logs to digital files. These geophysical logs are one of the tools commonly used in the interpretation of subsurface information in the exploration for oil and gas and, more recently, carbon sequestration activities. The resulting digital files are called RasterLogs (digital Raster files of the geophysical Logs). The digital files are in an ‘industry standard' TIF format.
Even though this is one of the most complete sets of these records for Michigan , we know it is not complete. For a variety of reasons some records were not available for conversion. If you have any records that will add to this collection and are willing to share them, the OGS will scan the files and return the source documents and the associated digital files.
In a collection of this size and complexity there are inadvertent errors and omissions. Please report problems or discrepancies you encounter. Your help is appreciated. Your feedback will help improve the quality of the collection.
Individual well files. If we have digital raster logs for a particular permit, we can email them to you. Email us with your request. We will send you one email for each permit you request. If we don't have a digital copy but the log that has to be copied by hand, you can get it with a Freedom of Information Act (FOIA) request and you will be billed.
To get a complete set of Raster Logs
send an external USB 2.0 hard disk with at least 80 GB of available space and the requisite cables. When hard disk is received a set of PWF will be copied and the hard drive will be return to the address provided.
Please send an email or include a business card with an email address so you can be added to the
PWF
/ RasterLogs email update notification list.
Return shipping
(UPS, FedEx, etc) is the responsibility of the party sending the disk drive. If return shipping is not provided, the unit is sent by US Mail. US Mail does not provide tracking and can take weeks to arrive. There are no other costs or fees associated with acquiring these files.
The USB hard disk drive should be sent to:
