Working with Raster Images

The TIFF images used by NeuraLog may be produced with practically any scanner.  The following sections provide information about TIFF images, as well as suggestions for scanners and scanning.

Image Resolution:  Dots Per Inch

Neuralog recommends a scanning resolution of 200 dots per inch (dpi).  Lower resolutions (say 72 dpi) may cause the automatic digitizing speed to suffer, and you may not be able to read all information on the log image as well.  Resolutions greater than 200 dpi may be used, but the results are larger files that increase space requirements.

Image Compression

All Neuralog products work with BMP, JPEG, and both compressed and uncompressed TIFF images, however compressed formats are recommended.  (B/W – Group 4 compression & Grayscale/Color – LZW compression).   

Color and Grayscale Images

NeuraLog will load both color and grayscale images.  Color may be added to images from within NeuraSection by picking tops and filling zones of interest.  NeuraView may be used to convert color or grayscale images to black and white.  Visit our web site, www.neuralog.com, or contact us for more information.

Large or Long Images

The size of images readable by NeuraLog is limited only by the available disk space.  NeuraLog only loads the needed portion of an image at any time.  This allows Neuralog imaging to work very quickly and to work with very large images.

Recommended Scanners

Neuralog offers the NeuraScanner, a high-end performance continuous log scanner designed specifically for well logs.  In addition, Contex wide format scanners are available that can scan multiple well logs at once, as well as maps usable in NeuraMap.

Cropping Images with NeuraView

If your images are oversized, that is, they contain too much white space, you may choose to crop them using NeuraView.  With NeuraView you can select any rectangular sub portion of an image and save out that sub image or splice sections from multiple images into one.  This allows you to have smaller images, resulting in less storage space.  You can also 'virtually' crop and de-skew images within NeuraSection.  This approach only affects the presentation of the image in the cross section so that the original TIFF image is preserved.  Though they can be printed as TIFF or JPEG files for use in NeuraLog.  For more information about NeuraView and NeuraSection, please contact Neuralog or visit www.neuralog.com.
