Keep your hydrocarbon flowing smoothly – thereby maximising your profit.
Flow assurance means effectively handling various solid deposits such as gas hydrates, wax deposition, scale, asphaltene and naphthenates. When your stream is interrupted, blocked or squeezed, it can cost your company money in decreased output and possibly in damaged assets.
Our Flow Assurance Software and services help you avoid those problems. They help you with early assessment of potential problems from solid deposition and guide you to the best remediation strategy or most efficient maintenance schedule. With more than 100 man-years of experience, our experts know how to keep the flow going strong.
KBC offers several Flow Assurance Software models to help with flow assurance:
Flow Assurance: Flow Assurance can be critical to upstream oil and gas projects and FEESA’s consultants & associates are recognised as amongst the best in the world. FEESA supports operators’ and contractors’ design teams with relevant and understandable flow assurance studies that greatly improve the work-flow of a project. Because Maximus was built with consultancy in mind, it often takes a central role in our studies; however FEESA consultants can use a range of other tools, such as OLGA for transient simulations, Multiflash for PVT analysis, CFD or bespoke modelling. The range of tools at our disposal allows for fit for purpose solutions, tailored to the problems / time available and, therefore, to the clients’ needs. Our consultants are highly qualified with the necessary project experience to enable them to take the most appropriate route to efficiently solve a Flow Assurance problem whilst integrating with, and supporting, a range of other engineering disciplines.
Field Development Planning: FEESA-FDP is a niche, independent consultancy serving the exploration and production sector of the oil and gas industry. We work in close co-operation with our clients, who have included small, medium and large IOCs, other engineering consultancies and contractors, providers of specialist intelligence to the oil and gas industry and training companies. Our goal is to assist them to achieve an optimum development plan for their hydrocarbon discoveries. Our specialists provide expertise in planning and execution services to support key stages of client’s decision making process.
Benefits of Combining Flow Assurance and Field Development Planning: FEESA consultants have added great benefits to projects by carrying out combined Flow Assurance and Production Forecasting studies using Maximus. On some projects we are working for the Forecasting group on the project, but in fact most of our Flow Assurance studies include a production profile forecasting element, even if we are not in the main production forecasting team on the project. As discussed in the following document, such studies generally lead to better surface facilities solutions, be it the investigation of a hi-tech solution (subsea separation and compression) or proving the feasibility of a cheaper conventional solution by the removal of unnecessary design margins.
FloWax is a powerful multiphase pipeline simulator with wax deposition modelling capabilities for flow assurance and production applications.
Through the unique blend of Multiflash’ advanced wax thermodynamics and a robust implementation of multiphase flows model in pipeline, FloWax allows Flow Assurance and Production engineers to predict the evolution profiles of:
Based on the predicted wax thickness profiles and the criteria required for wax management in production pipelines, the pigging frequency can easily be evaluated.
The built-in pipeline design tool allows including in the model, the pipelines’ geometry, building material, presence of thermal insulation as well the environment in which the pipeline is set. Temperature and Pressure profile from third parties simulators such as Olga can also be imported and matched.
FloWax embeds Multiflash thermodynamic modelling and petroleum fluid characterisation capabilities, however, model files generated with Multiflash standalone can also be used to model the fluid and solve flash calculations.
The multiphase flow model takes into account for different flow regimes as well as the heat transfer between the pipeline and the environment and models the deposition of wax along the pipeline walls, based on mass transfer method. The shear removal model developed with large flow-loop experimental data can also be included for highly turbulent regimes.
In FloWax the effect of entrained solid waxes on oil rheology is also taken into account to provide reliable predictions on oil viscosity. The model can handle the coexistence of wax sediment, hydrocarbon liquid, aqueous phase and gas. However, the number of phases actually present along the pipeline is determined by the full solution of the phase equilibrium calculation with the built-in Multiflash engine.
