Trace Viewer PDF Print E-mail


Background information

Trace Viewer was created by Xstract to provide fast, simple and lightweight visualisation of numerical downhole data. In addition to featuring standard visualisation functions, Trace Viewer allows users to interactively pick intervals of interest from downhole variables (e.g. geophysics, geochemistry) based on cut-off values. Users can dynamically change cut-off values and other parameters with the results being displayed live on screen. These intervals can be exported as text encompassing From, To and Length fields ready to be copied into other applications. Trace Viewer works with LAS version 2.0 data as well as ASCII comma delimited (e.g. CSV) files, and runs on Microsoft Windows. Xstract is pleased to release the core features of this technology to the wider community.


Trace Viewer works with Windows 7 and Windows 8, 32-bit and 64-bit versions.  It requires the Microsoft .net4 environment. The installer includes a check for .net4, and will prompt you to download and install .net4 if required.


Please contact Xstract if you wish to purchase a copy of Trace Viewer. If you have not used Trace Viewer before, a trial version can be requested.
