Testimonials

“I’ve had the pleasure of working closely with Serkan since 2018, starting with full five-day in-house support (before the home office era) and continuing through numerous workshops, trainings, and remote sessions over the years. His deep technical expertise and straightforward, solution-oriented approach have been invaluable – he quickly identifies the root of any issue and adapts effortlessly to different colleagues and communication styles.

Thanks to his support, we were able to implement advanced features in our models, such as wettability-altering surfactants in gas-condensate systems, and build our first fully integrated surface and subsurface network models. Most recently, Serkan ran a workshop at our Hamburg office, where he demonstrated the wide-ranging capabilities of the Model Designer – something we were able to immediately apply to our current well planning and drilling activities.

Serkan is always approachable, even outside regular hours, and consistently reliable. His contribution has been key in unlocking the full potential of the tNavigator software for our workflows, enabling faster, more comprehensive decision-making across our teams in Harbour Energy.”

“I found the course to be very instructive, highly useful and well supported. Given the limited time available, a considerable amount of information was imparted, which did give it the feel of drinking from the fire hydrant of, rather than the well of, knowledge. However, that was to be expected.
All presenters were engaging and welcoming of discussion and questions. I came away with a much sounder grasp of geostatistical techniques, how to use these to interrogate my data, which are better in which situation, and how to do so in tNav. Finally, I would like to thank RFD for organising this course. Having access to world-class knowledge is a luxury and a real benefit. Along with the Tech Summit, it was a fascinating week of what can be done in tNav”.

RFD’s tNavigator is, without exaggeration, the most comprehensive one-stop-shop solution for reservoir evaluation, simulation, and management. Its capabilities go far beyond traditional modelling. Just recently, the Assisted History Matching (AHM) module enabled me to successfully tune and match an exceptionally complex, overpressured compositional model in the Caspian Sea, involving 270 equilibration regions and 24 distinct compositional models.
Beyond that, we’ve also implemented phase permeability hysteresis for gas storage using tNavigator’s flexible functionality, and we’ve based an entire integrated modelling research project for coal seam gas on this platform.
I first met the RFD team over a decade ago—back when they were already wunderkinds, outpacing the competition with raw brilliance. Since then, they’ve taken all the Herculean steps necessary to evolve from a leading simulation tool into a world-class, fully integrated reservoir management solution. And now? They’re breaking new ground in the mining sector, delivering innovative, non-standard approaches with the same elegance and efficiency that have become their trademark.
What I value most, however, is the exceptional support provided by their technical team. Every team member is brilliant—but the responsiveness and depth of knowledge shown by Andres Bracho and Zakhar Lanetc consistently exceed all expectations.

“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.”

“I have been using tNavigator since 2013 and it has completely changed the way I do dynamic modelling. The amazing GUI makes switching between 3D and 2D maps seamless. Faster simulation run times sets this tool apart form any other in the industry. I am currently using the AHM module for a green field development sensitivity analysis, and found it very user friendly. The reduced run times help me test several scenarios with a range of different uncertainty parameters.

I would specially like to touch base  on the ARITHMETICS, which I believe is the unsung hero of tNavigator. ARITHMETICS, in my opinion is a revolutionary tool within tNavigator which gives limitless capabilities to do stuff on the fly. It greatly reduces engineer’s dependency on other disciplines to come up with additional information to support the evaluation.

Please keep doing the good stuff and hope we continue to benefit from the tNavigator suite in future.”

“The workshop conducted by Mark Lakos from RFD on the usage of tNavigator software was truly remarkable, especially for the Master’s students working on their group projects. In the first session, we delved into the fundamental steps of building geological models and running simulations. The second session was even more engaging, as we discussed specific points from our group project topics, while also gaining insights into additional tools like the PVT Designer, which includes advanced compositional models, the Well Designer, and more. These two sessions led by Mark were incredibly beneficial, serving as invaluable resources for us to design and model advanced projects across various fields such as oil and gas production, carbon capture and storage (CCS), geothermal applications, and hydrogen storage. This knowledge will not only aid us in our group projects but also significantly enhance our skills for our future careers in the real world. We sincerely hope to have more of these informative sessions for future students!”

“During the summer months 2023 I was working on a project simulating the effect of active zonal control by multiple ICV’s along producers and injectors. Even though I have been using tNavigator simulator for almost 10 years now, I never used Model Designer (MD) and/or Well Designer (WD). I started using MD and WD in June, two weeks before going on summer vacation, I was away for three weeks and picked up the modelling again in July. So, effectively, the first part of the work was done in a two-month period, getting accustomed to the software, setting up the models, and running a large number of scenarios. And yes, I got a lot of support from Oksana and Alexey, but from a software point of view, pretty effective I would say!”

“I had the pleasure of working with Angela and Alexey from RFD on a project to build a reservoir simulation model, which included network design to evaluate potential pipeline debottlenecking and infill wells for a gas field. Both Angela and Alexey demonstrated exceptional expertise and professionalism throughout the process, and I am thoroughly impressed with their contributions.

Angela’s deep understanding of reservoir dynamics was evident as she carefully guided the development of the simulation model. Her attention to detail and ability to address all my questions within a short time frame was fantastic. She communicated technical concepts clearly and was always willing to discuss and refine any aspects of the model to meet project goals.

Alexey’s strength in building the vertical lift performance curves and surface network was invaluable in assessing the potential for debottlenecking and impacts of infill wells on the overall production of the field.

Together, Angela and Alexey’s teamwork and expertise has helped to create a robust and reliable simulation model that provided us with clear insights for decision-making. Their responsiveness and problem-solving skills were much appreciated by our team.”

“I have been using tNavigator as the main reservoir simulator for a while now. Over the last half year, I’ve also moved integrated production modelling to tNavigator, and have together with good support from Rock Flow Dynamics built an integrated model that has the necessary amount of detail and includes two reservoir models. I’m therefore able to give realistic production profiles taking into consideration the behaviour of both reservoirs as well as their interaction and combined effects when flowing through the same surface facilities. Although there have been a few setbacks along the way while setting up the project, the support team has really made a great effort into solving the issues with high focus and the necessary people involved, and has even developed an additional update of the software to implement options required to overcome any challenges. All in all, I’m very satisfied with both running simulations in tNavigator due to its flexibility and performance, but also integrated modelling due to the ease of results post-processing of traditionally separate domains within the same interface.”

“As a heavy user of tNavigator Material Balance Analyser & Network Designer, the integrated software has improved the efficiency of evaluating multiple development scenarios. Over time, the software has continuously evolved, with new features and improvements being introduced based on real client feedback. The outstanding support team continues to provide excellent customer service which allows me to rely on tNavigator for all my Dynamic modelling needs.”

“We find tNavigator a very useful reservoir simulation tool through usage of the integrated modules that help us keep the projects in a single software solution which inevitably leads to reduced software spendings without sacrificing the quality. RFD has a great and responsive support team which provides excellent and swift services to our reservoir engineers.”

“tNavigator is a very well-rounded and powerful simulator. Its post-processor is intuitive. The customer tech support I’ve got from tNav, especially from Alex is the best that I’ve ever had. During the video support session, Alex answered all my questions and lots of questions that were out of the range of this video session agenda. Very impressive professional support!”

“We were one of the first teams in ONGC offshore group to start with the evaluation of tNavigator which helps ONGC with the procurement. Since a year and half, we have migrated most of our projects to tNavigator as it provides users with the flexibility, easy to use features like creation of restart files, quick forecast, bubble maps and significance reduction in the run time of the models.”

“On behalf of the Benin Secondees at Lime Petroleum, I would like to say thank you to Rock Flow Dynamics for making the industry this powerful software, tNavigator. Through the two-week training, I figured out how much faster and easier I can perform reservoir static and dynamic modelling as well as reservoir simulation and all other studies related to hydrocarbon reservoirs comparatively to competitive tools on the market. For our trainers – Jordan, Oksana, Elias, Sorin and Mark, I will never end celebrating you for your experience and the way you share your knowledge. We really appreciate your insightful training.”

“I have used many different dynamic reservoir simulators during my professional career as a Reservoir Engineer. In 2021, we decided to test tNavigator based on the many favourable recommendations from other colleagues. The many functionalities and easy to follow user interface caught our attention right away. I was running several models within the day we installed the software. We ran several benchmarks with the simulator we had previously and tNavigator came on top with flying colors. What has impressed even more about tNavigator and RFD is the impeccable technical support. It is done timely and RFD’s technical experts (Alexandra Kidd) are ready to engage either through e-mails or Zoom meeting to solve any issue we may have. Very happy to have taken the decision to go with tNavigator as our reservoir simulator.”

“tNavigator’s GPU acceleration is a game-changer, dramatically reducing calculation times. Additionally, the customer support is exceptional—responsive, knowledgeable, and always ready to assist with technical needs. tNavigator combines top-notch technology with dedicated support, making it a highly valuable tool in the industry.”

“The decision to purchase tNavigator was made six years ago due to the promising possibilities of very efficient hardware usage and parallel processing capabilities in the area of reservoir simulation. The customer experience has been outstanding and the support covers quickly any upcoming questions or challenges, furthermore customer requests can be implemented into the software within a very reasonable timeframe. tNavigator is easy to implement in any IT environment and during the last years all modules have been further developed to a very good and balanced software package which covers geo, well, fluid and surface network modelling in a practical and integrated way. These improvements convinced us to move completely and migrate all projects and models to use tNavigator as the main modelling and simulation platform.”

“I’ve had the pleasure of working with Alexey from Rock Flow Dynamics on several projects over the past year, where he provided outstanding technical support for tNavigator. His expertise and proactive approach made learning and applying the software a great experience. One of Rock Flow Dynamics’ biggest strengths is its people, and Alexey exemplifies this with his dedication and attention to detail, which played a key role in our projects success. Overall, I’ve had a very positive experience with both tNavigator software and the support team.”

“I have been using tNavigator since 2012, and the functionalities of the software have improved and developed through years in order to capture and ease geological and dynamical modelling workflows. By implementing fully integrated workflows in tNavigator pre-processor, we had opportunities to explore the range of possibilities and outcomes of an optimisation scenario in a shorter time, allowing the team to have more reliable and consistent simulation results. On a different project, the use of tNavigator during the appraisal stage was key for assessing the reservoir risks with a more objective approach, when compared to the classical exploration method. The integrated environment allowed us to carry out a quick, reliable study and make confident decisions. Following the results of this project, we have since adopted this approach in other prospects

I  would be very happy to recommend tNavigator as software package, as I am very satisfied with solution and the level of  support provided by the team.”

“Impressive performance of the software, easy to use, strong simulation capabilities. I liked the GUI and workflow of the post-processor.
RFD support team were very helpful in giving us advice on setting up the models and using the software. And also the RFD team helped us greatly by running the final simulations for us on their hardware, both so that we could report favourable performance results, and to ensure we met the deadlines for the project.”

“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.”

“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.”

“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.”

“It was my company’s first time to use cloud computing services for the reservoir simulation. RFD cloud configuration made the experience seamless. There were some simulation problems arising – mostly due to the fact that my experience with tNavigator is fairly new and we are running large and complex DPDP models – RFD would always be available with excellent helpdesk support. In fact this level of professional support stands out among simulation software vendors.”

“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.”

“We have been very impressed by the quality of the help desk support from the RFD office in Aberdeen. The staff are knowledgeable, helpful and friendly, and while the software is intuitive, I have no doubt that their assistance has saved us time. The software ‘does what it says on the tin’ and does it very well. On top that, RFD are very receptive to suggestions for new and improved features.”

“tNavigator has been a necessity in enabling our team to plan and successfully drill 6 horizontal wells in the past 6 months. It’s versatility and speed has allowed a fast but detailed progression of well placement and planning for effective reservoir development which would not have been possible on our previous software within the same timeframe. On top of this the technical and commercial staff at RFD have been more than helpful from day one – thank you.”

“AGR have been testing tNavigator on a recent full field modelling study. Our client and their partners requested the workflow for the reservoir model to be created in an alternative software package, but were willing to test tNavigator as much as possible during the modelling work. Due to the flexibility of tNavigator we were able to integrate the tNavigator ‘Simulation’ module into our workflow in a very efficient way and managed to cut down on simulation time during the course of the project. This saved us many weeks of ‘waiting on simulation results’-time and allowed us to conclude the project successfully.

Throughout the project RFD have been extremely supportive and able to help us through the few obstacles we encountered. I have been especially impressed with the turnaround regarding a little bug in the ‘Batch Jobs’ module, which was fixed and released within a matter of days.”

“Excellent! Thanks! Years have passed, and still, coming back to tNavigator I realize what simulator is the best of the best! There have been so much useful stuff added to it since 2012-2013!”

“I have been using tNavigator for several projects and it has made my work much more efficient.  From my experience tNav is not only fast but really easy to use and I have found the technical support second to none.  Quite simply I think tNavigator is best in class.  A real game changer.”

I have had a chance to test the tNavigator program for several years. tNavigator has grown from a simple fast dynamic simulator to a full package; covering seismic, static & dynamic modelling, PVT, well and network modelling. We decided to purchase a license and haven’t regretted it. tNavigator has good documentation, fantastic support, flexible options for modelling and is fast, thus we can spend more time analyzing results.

“The RFD team is always responsive and provides an excellent service. The compatibility of tNavigator with other industry standards is highly advantageous and the software itself performs very well with improved run times that help make smart work of sensitivity analysis.”

“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.”

“tNavigator is a powerful simulator which supports third party data input formats. The user interface is friendly which makes it efficient and easy to use. It is the best value for money on the market today.”

“I have been working with tNav and the RFD team for four years.

When I first started using tNav on a trial basis, I ended up using it exclusively as I realised it produced the same results as our existing software but much faster, allowing me to meet an important deadline which I would have struggled to otherwise meet.

The interface was basic but had the essential features a reservoir engineer needs. It is now much more sophisticated, feeling like a fully integrated package, having been continuously developed over the past four years.

The help desk are technically excellent and very helpful. From day one I had hands on help in the office despite only being on a trial license at the time. Covid-19 has almost improved this experience as it has become more acceptable to schedule a helpdesk video conference, often at a moment’s notice.

Dealing with RFD feels honest and direct. They are there to help us perform better in every way. Pricing is transparent and you don’t feel you have to review PO’s under a microscope for any catches.”

“I have been using tNavigator as my go to simulator for both my history matching and forecasting exercises on our complex 3-phase dual-porosity carbonate field. Thanks to the robustness of the methodology tNav implements for numerical convergence, tNav allows the user to take advantage of having large degrees of freedom for optimizing their simulation run time without jeopardizing the stability of their models. I highly recommend tNavigator for any Reservoir Engineer actively involved in day to day simulation.”

“Our team has been using tNavigator for the last 2 years, for a wide range of reservoir simulation projects in oil and gas, CO2 Storage, and geothermal projects. The technical support and the training delivered by RFD always meet highest standards of quality and our experience with the software was fully compliant with our expectations and needs. We are very satisfied with the provided services and solutions.”

I used tNavigator for several projects and was really impressed with the accuracy of results and the speed of calculations. My last project was a complex oil field to history match, with several producers as well as gas and water injectors. The run time using a third-party simulator was 36 hrs with single core and 1 hour with 20 cores (parallel). With tNavigator, the run time was reduced to ½ hour! (using GPU). Results were rigorously identical.

“I’ve used the tNavigator for a while now for our polymer study, but also other simulations since it’s so fast and it fits nicely into our Petrel workflow. It’s so intuitive that none of us had to attend any training course.”

“As a new user of tNavigator, I was very impressed by the solution provided by Rock Flow Dynamics. The abundance of self-help manual/tutorials, the optimal use of modern hardware, the relatively simple User Interface are all notably improvements on other industry software available. I have just finished building a history matched model on our Kraken field within a tight 3 month window and the speed of tNavigator running on our Cluster helped a great deal. Furthermore, I was able to rapidly create a range of forecasts, and to derive P10/P5/P90 cases, using tNavigator’s Assisted History Match functionality.”

“This year, we decided to change our simulation platform and build new static and dynamic models for our FDP course delivery. RFD tNavigator software platform and the amazing technical support team made this journey seamless. We were privileged to have access to the cloud-based licensing which was deployed for every student and academic usage. RFD team also worked very closely with us not only in building and configuring the models but also in providing excellent training sessions for the Master’s students. The graphical user interface is powerful, the software is robust, efficient and compatible with multiple simulator platforms. It executes numerical computation tasks with speed. Thank you for all your support. It is very much appreciated.”

“To model completion skins and pressure transients accurately very fine LGRs are required around the well. This has a large computational penalty and therefore a high speed simulator is required. tNavigator reduced my run time from 15 hours to just over 3 hours using a 10 node cluster. This allowed me to complete my project efficiently and incorporating full results from pressure transient analysis”

“I have been using tNavigator on one of the largest field development projects on the Norwegian Continental Shelf since the mid-eighties. The purpose of the simulation study was to investigate future-phase development scenarios and to perform a sensitivity analysis on facilities locations and processing constraints, including production and injection network modeling.

tNavigator turned out to be a major leap forward in terms of computation time, without compromising simulation quality and accuracy. The usage of tNavigator allowed me to run large numbers of simulations simultaneously, be able to QC results the same day, to fine-tune and start new simulations before going home. In this way I was able to almost quadruple the amount of scenarios to investigate.”

“The tNavigator tool has allowed us to streamline our subsurface workflows – we have been able to rapidly identify optimal drilling locations, run sensitivities and sense-check results through an intuitive and user-friendly GUI interface. The RFD team have been very helpful whenever problems arise, and respond quickly to any technical feedback. We hope it keeps getting better!”

“RFD provides a powerful tool ‘t-Navigator’ that every reservoir engineer should have. Using t-Navigator, we have managed to complete geological to dynamic modelling study within few weeks. t-Navigator has a user-friendly interface that helps engineers to build a simple geological sector model which can be fit for purpose for engineering use. And RFD’s support team is great help when we get stuck.”

“AGR have been very impressed with tNavigator. By utilising all of the computing power available in today’s multi-core workstations with a single license we have seen significant reductions in simulation time in a variety of models. This will aid in generating a more comprehensive range of development scenarios for a range of projects. A lot of hurdles that other simulator packages have “because that’s the way it’s always been” have been overcome with tNavigator, such as the ability to pause & step-in and make changes at any timestep. This, coupled with a straightforward GUI and compatibility with multiple simulator decks, makes it a very versatile and efficient tool for ourselves and our clients. With excellent user support from the team here in the UK and development centre in Russia, RFD have shown a willingness to take on board ideas and suggestions to optimise workflows together.”

“I want to thank you for the good qualified support and assistance in using the tNavigator software package and leave you positive feedback on this product. Currently, while work execution, I use tNavigator to create sector models and calculate on their basis a variety of options for uploading ASP to the Salym oilfield. Very friendly interface and high speed of the calculations of this product allow me to perform quite complex calculations with the maximum speed, and also to let to visualize a graphic material in high quality.”

“tNavigator has been a great help for our research and teaching. This year, I had six honours students who used tNav for their theses! I have also used tNav for my latest journal publication and using it for the OLYMPUS Optimization challenge. Thanks for all the support. It is really appreciated.”

“Thank you rfd for creating the tNavigator on Amazon cloud service. This is a revolutionary product that is accessible, scaleable and affordable. I have run simulations via an internet connection while traveling around the world on the AWS clusters. Multiple simulation cases can be run simultaneously, and I can scale up processing power by utilising additional computing nodes. This means my customers get insights faster saving valuable time. The most important benefit is to my bottom line, as I pay only for computing resources used. Whether it is a quick small model or a larger complex reservoir process, tNavigator on Amazon cloud has done it for me and my customers.”

Dear Vasilii,

I’m writing this letter to thank you and RFD Houston team.

We used tNavigator to build a gas reservoir model for one of our consulting projects and were pleasantly surprised with how easy and quick we could do this. We used a new product of RFD – tNavigator Model Designer. In my opinion it is good and efficient product. The interface is very intuitive, the product is very responsive and executes tasks on the fly. After only about half day of working with the help of RFD software support engineer (who was excellent!), we were able to build a grid that takes into account geometry of faults and bed surface, find the right static and dynamic properties of the model and match the model with respect to estimated resources. Also we were able to make the first production simulation run.

It is worth noting that we had essentially no prior experience with tNavigator. As a user of various geological and simulation packages with roughly 20 years of experience I can say that tNavigator Model Designer has a unique combination of tools combined with an exceptional ease of use that puts this subsurface software well ahead of the competing static simulation packages.

As our industry is getting into the new age or competition we have to learn to do more with less. your product helps us to do exacly that. Do more reservoir simulation work with less financial and human resources required.

I wish you and the company you are leading all the best.

Thank you!”

“Occasionally someone comes along with a truly new approach. And is usually met with disbelief, because the status quo is always more comfortable. With over 35 years experience in reservoir simulation, I would like to say, that tNavigator have created this Eureka moment and have taken simulation into the 21st century. Superfast processing comes with synchronised GUI for maps, line graphs and well diplays; it allows for immediate timestep by timestep analysis of the history match in progress. Stop/Retrace/Start technology allows for ad hoc intervention during a run, alleviating the need to wait to the last timestep; effectively conducting multiple runs in one. Interogation of the results is so improved, that one now considers whole new data, which were previously left untouched. Truly a game changer!”

“Having been a user of reservoir simulation for over 30 years, I was looking for the next step change in technology that allowed us to do the things we wanted to do, at the resolution we wanted, in an acceptable timeframe and at reasonable cost. RFD achieved this, and I’m sure will achieve a significant part of the reservoir simulation marketplace as others realise that this is a step change in the performance/price value driver.”

“We’ve been mainly using the tNav simulator for heterogeneous petroleum reservoirs of low, to very low, permeability; in primary and secondary recovery.

Our experience so far has been very positive, both, for its main functions and many of its complementary features.

It’s high speed processing has allowed us to simulate models with a great quantity of cells, increasing the model resolution. This way we were able, for example, represent in detail the stratigraphic characteristics that control the dynamic behavior in the reservoirs we are working on.

The simulator Assisted History Matching procedures allowed us to get, in short times, “adjusted reservoir characteristics”.

The use of the Split & Merge Module was very useful, enabling us to achieve the required flexibility in our workflow.

The explicit simulation of the well hydraulic fractures has granted us the possibility to achieve a better History Matching and, as a result, more accurate forecasts in complex low permeability and high heterogeneity reservoirs.

Being a finite difference simulator, tNav has good numerical convergence but also has the ability to express the results in 3D Streamlines. This has enabled us to optimize Secondary Recovery Volumetric Efficiencies. To the above it is added the so-called “Management Waterflooding” that optimizes the flow of water injection in the Secondary Recovery Processes.

Finally we have found in tNAV an excellent tool for the simulation of complex fields, saving time and money in the reservoir management of the field development and exploitation.”

“I would like to express my appreciation for RFD’s outstanding support and thank your development team for adding surfactant modeling capabilities to tNavigator. Use of this feature in our simulation work has advanced our understanding of surfactant flooding potential in the Spraberry oil field in West Texas.”

“tNavigator became a software of choice for reservoir studies carried by TGT Oil & Gas Services company and Sofoil company in 15 countries, including Russia, USA, South-East Asia and Middle East. The multicore-optimised design of tNavigator solver opens the gates to full-field simulations on original geological fine-grid and allows bypassing detrimental upscaling procedures. The simulation time is reduced from weeks to hours.

The time and space resolution of sector modelling has substantially increased and now avails very accurate side-track modelling and production forecast which form the basement for drilling justification.

The enhanced computation speed allows simulating short-term pressure responses with tiny time steps and micro-fine grid, which opens new horizons in cross-well pressure pulse testing and account the actual geology of the area, actually well locations and trajectories, actual production history and interference between wells.

tNavigator is the first software on the market to provide user-friendly calibration facility for the holes where along-hole flux profile has been measured, which allows integration of time-lapse production logging data into a reservoir model and corresponding changes over time.”

“…This study shows that high-resolution fine-scale reservoir simulation can be used to improve modeling and understanding of interactions between the matrix and fracture systems of the Spraberry. The use of a reservoir simulator optimized for processing on multi-thread, multi-core CPUs makes possible reservoir studies using high resolution models that were once impractical due to lengthy run-times.”
