Handle any number of processing facilities, compressors and processes through fully customisable nodes. Model different types of product recovery, compression systems, along with their constraints and easily identify product bottlenecks.

Flexible Pipeline & Transmission Models


Model single and multiphase flow within pipelines with any number of mixing and delivery points. Single phase models like Weymouth and Panhandle and multiphase models like the Beggs and Brill and Hagedorn Brown are all available from within the tool. Find potential flow assurance issues through pipeline temperature profiling and pressure constraint monitoring.



Automatic Event Triggering

Use FlowAssure’s automatic event triggering to determine optimal timing for platform and compression initialization.

Incredibly Fast Model Run Times

Frequently Asked Questions

What makes FlowAssure unique?

FlowAssure is the fastest and only truly integrated market driven solution available today. With this tool planners and engineers can determine exactly what and when to execute changes in the production system to meet the hydrocarbon demands of today and the future.

What’s more FlowAssure allows users to run both fully compositional and black oil models simultaneously and even mix both models to evaluate production forecasts from any type of field available.

Why is FlowAssure so fast? Is there a compromise in results?

FlowAssure is fast because of its unique solver that uses an advanced set of processes crunching through solutions faster than any other simulator. The best part is that, because we are not cutting corners, there is absolutely no compromise in the granularity or precision of the results.

In many instances, in fact, FlowAssure generates more information and gives users more useful results than other conventional tools. Furthermore, a lot of work has been done in calibration and QA so you can rest assured that all results obtained from FlowAssure are accurate and comprehensive.

What is market driven?

Market driven means that the system’s solution is reached based on end product specifications so any changes in market forecasts are incorporated into the final solution. FlowAssure’s solver starts from the market where it calculates the system conditions that are needed to satisfy market requirements and works its way down the model calculating the events and parameters in each node until it reaches the hydrocarbon source. This method of solving the production system ensures that market requirements are met, optimizes production, and maximises company revenue.

Can FlowAssure handle both, three phase and compositional models?

FlowAssure is unique in that it offers users complete flexibility around the type of model they want to work with. Users can build fully compositional models with no restrictions on the number or type of components they want to simulate, or they can build traditional black oil models based on oil, gas and water rates.

What is more, users can create three phase models and connect them to fully compositional models and vice versa allowing them to account for every model type in their system.

Is it fully supported?

FlowAssure is fully supported by our team of dedicated developers and engineers. We love what we do and we take pride on the quality of our software. Problems are usually resolved quickly through contacting any of our friendly team members. For a more comprehensive and full support we also offer ad hoc consulting services.

Is it compatible with other software?

FlowAssure is fully self-contained and can be utilized without any other supporting tools. Nevertheless, reports and results from other O&G tools can be used as input through the easy to use FlowAssure interface. ResAssure reservoir models, for example, can be directly linked into FlowAssure for a more granular view at the fields subsurface system. Regardless of what tools are used, the final outcome is an optimised, resilient distribution system best able to respond to technical changes and market fluctuation.

How fast is it really?

FlowAssure’s state of the art core uses a proprietary solver method that calculates systems of equations in record time. Small hydrocarbon fields (<20 wells) run in a matter of seconds, while medium to big (>20 wells) run in a matter of minutes.

For one of our case studies in 2015, we attempted modelling the supply system of an entire country with over 4000 producing platforms and 11000 individual nodes. Simulations for this model ran in only a couple of hours.

What does full integration mean?

An integrated asset model is the best way to break down knowledge silos that indubitablyexist in every organization. Full integration means that you will be able to view the entire hydrocarbon production system from its initial state in the reservoir up until the point of sale in the product market, all in one single model.

With FlowAssure you will be able to model aquifers, reservoirs, completions, tubing and wellheads, production platforms, compressors, processing facilities, delivery points, and markets all in one tool. What is more, all of these nodes are able to communicate with each other and find a common solution, allowing planners and engineers to evaluate the effects of one parameter on the entire system.

Is it easy to use?

Years of work have been put into FlowAssure’s interphase with user friendliness, usability and accessibility at the core of the improvements. FlowAssure’s model builder has been developed so that anyone, from a graduate to a senior engineer, can build a model in a matter of minutes.

Can I take into account uncertainty in input parameters?

FlowAssure counts with scenario and probabilistic analysis tools that allow engineers to carry fully fledged sensitivity analysis studies and take into account any uncertainty in input data. This is a feature that is a perfect fit for FlowAssure as its unparalleled speeds allow it to run full probabilistic studies in a matter of minutes. Users can generate any number of discrete scenarios using the scenario builder function or construct a sensitivity analysis study applying a variety of probability distribution functions to virtually any input parameter.

What type of reports can I generate?

FlowAssure generates an enormous amount of information and thanks its flexible report generator, the number and type of reports that users can create is almost limitless. FlowAssure comes with a set of popular in-built reports and the functionality to create user generated reports with any structure and results. Reports can be generated in daily, monthly, quarterly, and yearly time steps depending on your projects characteristics. These can also be easily viewed and plotted at the click of a button, or they can be exported to Excel for further analysis.
