Scanned West Virginia Wireline Logs Available

Example: Portion of a Scanned Log

What is available?

Scanned images of selected West Virginia wireline logs are available online. The images are TIFF files, named by API number, and downloadable directly from the Survey's web server or through the Survey's well-based data systems, "pipeline-plus" and "pipeline." To date, logs have been scanned for over 25,000 wells. The West Virginia Geological and Economic Survey (WVGES) gratefully acknowledges that its primary funding for this project came through the US Department of Energy's (DOE) Office of Fossil Energy through the National Energy Technology Laboratory (NETL), contract number: DE-FC26-05NT42661. WVGES also appreciates assistance from various oil and gas companies.

How do I get the images?

You can download any of the logs that the Survey currently has scanneddirectly from the Survey's web server or through "pipeline"--either of which can be accessed using a Web browser. Files are available directly from the web server at downloads.wvgs.wvnet.edu/welllogs; these files are organized within county-based folders. Files are available through "pipeline" at wvgs.wvnet.edu/oginfo/pipeline/pipeline2_intro.asp by selecting the "Logs" option; these files are organized by county code/permit number and can be accessed one well at a time. All images are TIFF, tag image file format, files (.tif) and named using the convention described below¹. The images have been scanned at 200 dpi generally using a black and white or grayscale setting although a few files have been scanned in color. Files sizes range from about 15 KB to more than 50 MB with size dependent on log content and scan settings.

Can I look at the image before downloading it?

We recommend you save the log image file to your machine for faster viewing. A log image file (.tif) may be viewed using various software including AlternaTIFF. Please be aware that not all image software will open our log image files because of the large image sizes. AlternaTiff is available from http://www.alternatiff.com.

How do I get help?

Please call the Survey at 304-594-2331 if you need help. If you encounter difficulty downloading files, please ask to speak with John Saucer. If you have questions about the logs themselves, please contact Philip Dinterman.

How else can I get these logs?

If you are interested in obtaining log images on CD, for a fee, please get in touch with Philip Dinterman at 304-594-2331.

¹ Scanned Log File Naming Convention

File names are undergoing modification currently to meet the Survey's file-naming convention shown below. Although many of the file names have been standardized, not all have. File names are being updated on a daily basis.

abbreviated API number = 10-digit number in which digits 1 through 2 are the state code (47), digits 3 through 5 are the county code, and digits 6 through 10 are the permit number with both the county code and the permit number padded with leading zeroes as necessary;
plus a one-letter designation for each curve² starting with the curves listed on the log header followed by any additional curve(s) shown on the log but not listed in the header with an "o" for "other" curves listed last;
plus a number, if necessary, to distinguish files with names otherwise the same (such as from different depth ranges, different time period, etc.);
plus "_a" for "Log Analysis", if included;
plus "h" for reduced-scale (usually to 50%) logs that have been scanned.
