FAQ: How do I use the online Kentucky oil and gas well records?

Kentucky oil and gas well record data is now available online. Several questions concerning its use often arise.

Why can't I see any images?

You need the DjVu Web browser plug-in available from Cuminas to see the records. DjVu provides efficient compression and the ability to collect well record images into a single, multiple page document. Select the version that is compatible with your system (32 or 64-bit Windows). NOTE: the DjVu plug-in is NO LONGER available for Mac OSX. The only workaround for this is to use a Windows machine. Click "NEXT" and then click "Download" on the End User License Agreement popup to download.

When you download the plug-in installation file, make sure you save it somewhere where you can find it easily. Recommended locations include: the Desktop or the temporary folder on your local hard drive (usually c:\temp). Install the plug-in by double-clicking on the downloaded .msi file.

Will installing DjVu mess up my computer?

The short answer is we don't know and cannot be held responsible if you have problems. Neither the Survey nor Cuminas have any idea what software or other plug-ins you might have installed. It is up to you to download and install the correct version of DjVu. On the systems we have tested, no problems were encountered.

I have down loaded the plug-in and I can't see any records.

You must execute the plug-in distribution file to actually install the plug-in. Find the executable file and double click on it to start the installation process.

I have installed the plug-in and I still can't see any records.

Over the past several years, DjVu has become a decreasingly popular document compression standard, and support for viewing DjVu on multiple platforms has decreased. Currently, you can only view the KGS documents on a Windows operating system with the Firefox, Internet Explorer, and Google Chrome (version 44 and lower) browsers. Stand-alone DjVu applications will NOT work, and you cannot view these documents on Mac OSX operating systems or mobile devices. A helpful FAQ about accessing DjVu files is provided here by the University of Georgia..

That's really too bad about DjVu, what's going to happen?

KGS is now in the process of converting all the current oil and gas documents to PDF format. PDF documents are larger than DjVu documents, but are more widely used, are available for viewing in most modern browsers without a plugin, can be viewed on mobile devices, and can be downloaded and viewed in stand-alone applications.

Both the DjVu and PDF formats will be provided for existing documents, and future documents (after the conversion process is complete) will be provided in PDF only. KGS expects this conversion process to be complete by early 2016 (Jan/Feb).

Why are the records available free of charge?

The Kentucky Geological Survey has maintained libraries of oil and gas well record data in Henderson and Lexington that are free and open to the public. When the decision was made to archive these files as digital images, the Survey made a commitment to provide the same level of data access as was provided in the file rooms. This means, you can look at the records at no charge.

What do all the buttons on the toolbar do?

Point to each of the buttons and wait a bit. A description of the button will be displayed.

How do I select the next record?

The first page of each record file is a page that provides instructions on using DjVu to view the records. Use the select page dialog box, navigation arrows on the right end of the tool bar, or double click on a thumbnail image to see the selected record.

I don't see any thumbnail images.

If the thumbnail images are not displayed in a column to the left, right click anywhere within the boundaries of the displayed image. Select "Show Thumbnails" from the pop-up menu. Newer versions of DjVu display a choice for "Navigation Pane" in the pop-up menu. Click that choice then click the Thumbnails choice to display the thumbnail images.

How do I print a record?

Right click on the image and select Print or click the printer icon on the DjVu toolbar. To print only the record you are viewing, set the Print Range to Selection. To make the entire record fit on a single page, select Reduce to Fit. To print that part of the image displayed at the current zoom level, select Current Zoom. After making your selections, click OK.

If you choose to print by using the printer icon on the toolbar, be sure to use the icon button on the DjVu tool bar. The icon button on the browser toolbar will print a blank page.

When I print, all I get is a box on an otherwise blank page. What's wrong?

Using File | Print or the print icon on the web browser tool bar will not usually print the document. Click the printer icon on the DjVu toolbar at the top of the image window (by default) or right click on the image and select Print from the pop up menu. See "How do I print a record?" above.

No matter what I do, only the top part of the electric log prints, or it prints too small to see anything. What do I do?

Use the zoom and pan tools to display the part of the electric log you want printed. Click the printer icon on the DjVu toolbar, set the print range to Selection, and select Current Zoom. Click OK.

How do I print a continuous electric log?

DjVu does not support continuous printing. There are several options:

  1. See "How do I print a log to scale?" below.
  2. Print out overlapping sections of the log and tape them together.
  3. Right click on the image and select Export to File... and save the image as a bitmap (bmp). Open the image you saved with a program that supports banner mode printing, load your printer with continuous paper, and print it.
  4. Contact KGS Publication Information Center or call 859-257-5500 to request a continuous copy of the log from the Kentucky Geological Survey Data Center. There is a fee for this service.

How do I print a log to scale?

Well logs are printed at standard vertical scales like 5 inches equals 100 feet. Printing to scale is a function of the print drivers you have for the output devices installed on your system (and not a function of DjVu). If you need to calculate the page size, black and white log images were scanned at 300 dpi; color images were scanned at 200 dpi. To print:

  1. With images displayed in DjVu, click the print icon on the DjVu toolbar or right click on the image and select print from the popup menu.
  2. Select an output print device that will support continuous images. A sheet feet laser printer won't work. For this example a plotter that supports postscript print drivers is assumed.
  3. In the properties dialog for the printer, set the output page width to 9.25 inches in the custom postscript page size dialog.
  4. Set the page length to a length exceeding the probable output length.
  5. Make sure the print scaling is 100%.
  6. Close the printer properties dialog box.
  7. In the DjVu print dialog, set the print range to the current page ("Pages from: n to: n")
  8. Select the option to print at the original size ("Orig. Size").
  9. Click OK to send the job to the printer.
  10. This can be wasteful of paper if you don't have standard width geophysical log paper.
  11. If you have software designed to print continuous log images, it may be better for you to export the file as a bitmap, convert the bitmap to the image format used by your software (often a tiff image), then import and print the log.

Long electric logs are broken into sections. Can I get a continuous image?

Due to limitations on the size of images supported by DjVu and to speed image access times, many long elogs have been cut into sections that overlap with match lines indicated. You can download and save the individual log sections as bitmaps then compose a continuous image with some image processing programs. Alternately, tagged image format (tiff) images are available of the complete elog. Contact KGS Publication Information Center or call (859)257-3896 to request a continuous image of the log from the Kentucky Geological Survey Data Center. There is a fee for this service.

Some well records have an elog that says "Demo Image" that doesn't belong to the well. How do I get a copy of the actual elog?

Not all of the available elogs have been scanned. To indicate an elog is available but hasn't been scanned, the image for a dummy, place-holder log has been added to the record. If you need a particular elog, you may request that it be scanned and added to the online system. Contact KGS Publication Information Center or call (859)257-3896 to request a log be scanned.

New well logs are being added to the system daily. Logs for new wells are scanned as they are received. Logs for older wells are being processed by county as well records are being reviewed for final archiving. Please confine your request to a few logs that are critical to your particular area of interest. Requests to scan all the logs in Pike County, for example, cannot be processed in a reasonable time. Your patience is appreciated and all the logs will be available as soon as they can be processed. If you need more logs in a time critical situation, we suggest you bring a copier to our offices in Lexington or Henderson and copy what you need. Contact KGS Publication Information Center or call (859)257-3896 to get more information about requesting an appointment to visit the Data Center in Lexington and set up your own copier.

How do I download the records?

Right click on the image. To download a compressed DjVu version of the records, choose Save Page As... to save only the current page or Save Document As... to save the complete set of well record images. When saving the document, be sure to select the Bundled option. To save the image as a bitmap for use in other image processing software, right click on the image and choose Export to File...

How do I get the well record images for a whole bunch of wells or every well in Kentucky?

KGS Staff can download images for well records to a CD-ROM and send it to you. Contact KGS Publication Information Center or call (859)257-3896 to get more information about requesting a CD-ROM of image data. There is a fee for this service.

For large numbers of wells (more data than will fit on a couple of CD's) contact KGS Publication Information Center or call at (859)257-3896. She will assist you in obtaining a network attached mass storage device (a "snap" server or other device). KGS Staff can then download all the images to the storage device you provide. There is a fee for this service.

KGS Staff cannot develop custom database or mapping applications for you to use to access the image data down loaded to the attached storage device. KGS developed the public online oil and gas well record system to provide these capabilities. If you purchase data on a server, you will also have to download or purchase the well identification (or header) data required to provide an index to the images, load the data into a database application, and set up the procedures to query and display requested information. KGS cannot configure the device for you so it will run on your local computer or network.
