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.
Andrew Moore, Senior Reservoir Engineer, Cabot Energy Plc
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.
Iain M Campbell, Reservoir Manager, I3 Energy
“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!”
Calum Hunter, Petroleum Engineering Manager, Ping Petroleum, United Kingdom
«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».
– Nolwenn Perzo, Staff Reservoir Engineer, OPC, London, United Kingdom
“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.”

“We have been gladly surprised by tNav performance. From our experience tNav is very versatile and fast. The visualization interface for initialization, history match and prediction results is highly user friendly. The optimization in computational resources and processing speed offered by tNav have allowed us to perform in a very reasonable timeframe a variety of scenarios such as: Assisted History Match and uncertainty analysis to identify key variables controlling reservoir performance in black oil aquifer –driven reservoirs. It is relevant to highly the significant and constant efforts made by tNav to improve their software features and compatibility with other reservoir geoscience and engineering softwares available in the market. Last but not least, we are very satisfied with the software technical and commercial support. The speed of quality of these are remarkable.”

«Уважаемый, Василий Георгиевич!
Настоящим письмом хочу поблагодарить Вас и команду РфД в Хьюстоне.
С помощью tNavigator мы построили модель газового месторождения для одного из наших консалтинговых проектов и были приятно удивлены тем, как легко и быстро мы справились с такой задачей, используя новый продукт компании РфД — Дизайнер Моделей. По-моему мнению, это весьма эффективный инструмент с интуитивно-понятным интерфейсом, выполняющим расчеты на лету. Нам потребовалась половина рабочего дня, чтобы построить геологическую сетку, которая учитывает геометрию разломов и поверхностей, верно определить статические и динамические свойства модели, скорректировать модель в соответствии с установленными запасами, запустить модель на гидродинамический расчет. Данный проект нам помогал выполнить инженер технической поддержки компании РфД, который был великолепен!
Стоит отметить, что у нас не было предшествующего опыта работы с tNavigator. Как опытный пользователь с 20-летним стажем геологических и гидродинамических пакетов, я могу сказать, что Дизайнер Моделей имеет уникальную комбинацию инструментов в сочетании с исключительной простотой использования, что позволяет продукту занимать лидирующую позицию среди конкурирующих пакетов моделирования.
Текущее развитие промышленности вступило в новую эпоху конкуренции: делать больше с наименьшими затратами; делать больше гидродинамических расчетов, задействовав при этом минимум финансовых и людских ресурсов. И Ваш продукт абсолютно точно соответствует этому лозунгу.
Желаю Вам и компании РфД, которую Вы возглавляете, всего наилучшего!»

“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!»
— Bruce Stevens, Reservoir Engineering Consultant, EnQuest
“The tNavigator technology represents a game-changer for us compared to other reservoir simulation software in our organization. We not only can tackle far more complex reservoir models with the software, but we are also able to fully exploit the exceptional speed of tNavigator in combination with our assisted history matching software to significantly reduce project cycle times. This in turn has made reservoir simulation a much more valuable tool to our organization.”
— Larry Murray. Manager, Waterflood Modeling, Occidental Oil and Gas California Operations
“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.”
— Steve Flew. Technical Director, Petrofac Malaysia
“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.”
— Peter Roberts, Reservoir Engineer, AGR TRACS International Ltd
«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.»
— Paul Tijink. — Lead Reservoir Engineer
«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.»

“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.”
— Mirta Córdoba de Galacho. Technical Director, MG&A Oil&Gas
“tNavigator is applied to a model of complex multizone gas condensate reservoir. It exhibits parallel acceleration of over 100 times on our 256-core cluster compared to single core runs. This allows our reservoir engineers to try many different production forecast scenarios each day”
— Alexey Yazkov. Deputy Director, NOVATEK Research and Development Center
«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.”
— Arthur Aslanyan. CTO, TGT Oil and Gas Services
“tNavigator makes the reservoir models in our company practical for engineers in the field. They are able to perform a thorough analysis of the reservoir dynamics and make their everyday decisions without years of experience with reservoir modeling software.”

“…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.”
