“As operator of the Draugen field, OKEA was eager to test an alternative simulation tool on our existing reservoir models. The generosity of RFD with respect to offering a trial license and support in customizing our existing simulation model was much appreciated. Very few modifications of the input deck were necessary. Results from our tests were impressive, both in terms of user friendliness of the GUI, accuracy of the calculations and CPU performance. We’re now a regular customer of RFD and have integrated tNav into our workflows.”


“I am an experienced geomodeller, having previously used many of the well-known software packages available. tNavigator geomodelling (Geology Designer) is new technology whose functionality is improving all the time. Geology Designer is now in a place where I can build all the technically challenging geomodels that I need. The software support from RFD is very good, and the time taken for RFD to implement new functionality in Geology Designer is short. I would be very happy to recommend Geology Designer in tNavigator to anyone looking for an alternative geomodelling software package.”

Senior Geologist, Serica Energy (UK)

“We have been using tNavigator for the last 2 years. It has reduced our simulation run times allowing us to have more detailed models (more cells) and to conduct an important sensitivity analysis that improves our decision-making process in uncertain scenarios.

The Argentina and Colombia RFD team arranged several training sessions that enabled us to make full use of the software’s capabilities. The product has been excellent, and with its professionalism and friendliness, the support team has made a huge difference.”

Senior Reservoir Engineer, GeoPark

“By using tNavigator advance technologies, we had better opportunities to explorer more complex and challenging tasks related to static and dynamic modeling workflows that we were hesitated to apply them in the past due to software’s and hardware’s limitation. Currently we are considering RFD as the key strategic partner who is providing us with great technology and technical support to fulfil our goals and visions in very efficient and practical ways.”

Principal Reservoir Engineer (Simulation), Abu Dhabi National Oil Company

“I found tNavigator really easy to use with extensive functionality and helpful manuals and on-line training. The geological modelling capability in Geology Designer has massively improved over the last few years and provides a fully functioning platform for geomodel building, with the advantage that it is directly coupled to the core simulation elements of tNavigator. The new functionality of Ensemble Modelling AHM within tNavigator has also given us the ability to investigate the impact of key uncertainties (both static and dynamic) across a large numbers models and significantly improve the history match of all cases at the same time. This is really useful when dealing with large or complex fields were a significant number of factors are important, especially key geological uncertainties or variables as we can include these in fully integrated workflows.”
