Edit, interpret and model logs in a single interface.

The Geolog™ Geosteer™ add-on module enables the geosteering expert to effectively edit and interpret logs in highly deviated wells, and model the Logging while Drilling (LWD) tool response. Geosteer works in collaboration with Sysdrill™ Well Planning and Drilling Engineering applications. This provides a powerful log-scale interpretation capability that integrates petrophysical, geological, geophysical and drilling workflows.


This integrated application group provides a well planning environment in which complex well paths may be designed and engineered for optimal placement in the reservoir, based on a combination of seismic, geological or reservoir data. Real-time WITSML data can be entered into an integrated database for visualization using the SeisEarth™ 3D Canvas.

Geosteering benefits

  • Geolog Geosteer gives users the independent ability to model, monitor and interactively modify a well in real time, independently of the LWD supplier.
  • Geosteer increases productivity, reduces drilling risk and optimizes wellbore positioning in the reservoir.
  • Geosteer is performed within the familiar Geolog user interface, and runs on Windows® and Linux® platforms.
  • Geosteer offers an effective way of interpreting log data in highly deviated wells.
  • Geosteering can be done at rigsite or at the office.
  • Support for WITSML real-time drilling data transmission using OpsLink™.
  • The Epos™ interoperability integration framework provides smooth workflows between drilling, petrophysics and geology/geophysics.
