[Next Question]

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 Celartem (was LizardTech) to see the records. DjVu uses MrSID technology to provide efficient compression and the ability to collect well record images into a single, multiple page document. When you download the 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). It is recommended that you use the manual download and install (Download Option 2).

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 Celartem (was LizardTech) 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.

DjVu works with current versions of all popular browsers: Internet Explorer 7 and 8, Firefox 3.x. It is recommended that you use the manual download and install version of DjVu; see the DjVu download page to update. If you download and install any new browser, you should download the latest version of DjVu and install it after installing the browser.

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 "Layout" from the pop-up menu and enable the Thumbnails choice.

How do I print a record?

Right click on the image and select File | Print or click either printer icon on the DjVu or web browser toolbars. To print only the record you are viewing, set the Print Range (from and to) to the current page number. To make the entire record fit on a single page, set Page Scaling to "Fit Page." To print that part of the image displayed at the current zoom level, set Page Scaling to Current Zoom. After making your selections, click OK.

To print a specific section of a document (a selected portion of a wireline log for example), you must first make a selection. Right click on the image and choose Selection from the pop-up menu. Click and drag and drop a box to highlight the portion of the record you want to print.

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

Newer versions of the DjVu plug-in have corrected this problem.

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. To print a specific section of a document (a selected portion of a wireline log for example), you must first make a selection. Right click on the image and choose Selection from the pop-up menu. Click and drag and drop a box to highlight the portion of the record you want to print.

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. To export the current DjVu image, right click on the image and select File | 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. To download a continuous image of the complete wireline log, click the Image/File Download link available for each of the oil and gas record search results.
  5. Contact the Public Information Center to request a continuous paper copy of the log. To build a request for specific logs, the Image/File Download link for each well includes a Request Printing service. You can also request a selection of wireline log images to CD-ROM or DVD. There are fees for these services; contact the Public Information Center for pricing information.

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?

Yes, tagged image format (tiff) images are available of the complete elog. To download a continuous image of the complete wireline log, click the Image/File Download link available for each of the oil and gas record search results. If you want a large number of log images, contact the Public Information Center to request a selection of wireline log images on CD-ROM or DVD. 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. The oil and gas well search results page will display a check box; click to request the scan. For more information, see KGS Policy for Customer Scanning Requests for more information.

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.

How do I download the records?

Right click on the image. To download a compressed DjVu version of the records, right click on the image and choose File | Save Page As... to save only the current page or File | 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 File | 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 or DVD and send it to you. Contact the Public Information Center to make a records request or to get more information. There is a fee for this service.

For very large numbers of wells, contact the Public Information Center to request assistance you in obtaining and submiting a mass storage device (a "snap" server, USB drive, 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 downloaded to any external 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.
