Mind the Gap: Managing Geological Uncertainty with tNavigator
Enhancing Potential of Geothermal Projects Using Integrated Production Modelling Approach
“tNav’s geosteering module was instrumental in the success of a CBM project in Mongolia, offering an easy-to-learn, integrated platform for planning, executing, and updating well trajectories. It enabled efficient training of new geologists, reduced data transfer time, and improved geological understanding with real-time model updates and seismic integration. The software is flexible, supporting both basic and advanced workflows (including Python scripting), and is compatible with various data input methods. Customer support was responsive and adaptable. Overall, the software is highly recommended.”
