Well Log Scanning price is negotiable. - Digital Geophysical Logs LOGDIGI recently initiated a program to digitally scan paper copies of well logs using a scanning device designed specifically for this application. Well logs can be converted to digital form in two basic formats-vector and raster. The most common file format used for vector digital logs is the Log ASCII Standard (LAS). Raster-format digital logs are simply images of the logs from a scanner, usually stored in TIF format.
