Techlog is a Schlumberger owned Windows based software platform intended to aggregate all the wellbore information. It allows the user to interpret any log and core data. It addresses the need for a single platform able to support all the wellbore data and interpretation integration workflows, reducing the need for a multitude of highly specialized tools. By bringing the whole workflow into a single platform risk and uncertainty can be assessed throughout the life of the wellbore.


History of Techlog

Techlog software was developed in Montpellier (South of France) by a company called Techsia. Techsia were formed in 2000. The first version of Techlog was commercially available in 2002. Techlog was developed to have a familiar modern interface providing easy visualization and interaction of all the data, with a pre-arranged workflow that enabled less experienced users to follow, Techsia made the multi-well interpretation more accessible to all technical experts. In 2009, Schlumberger acquired Techsia and the Techlog platform and they currently support and market Techlog. Techlog offers new functionality in each new release, not only in petrophysical and geological interpretation but also geomechanics interpretation, uncertainty and links to the industry standard platform like Petrel. Techlog also has the new acoustics module which will add much more functionality into the application.
