Fluid Analysis and Simulation Environment

Overview

RF-DAP FASE is a fluid analysis and simulation environment that predicts the phase equilibria and estimates physical, thermodynamic, and transport properties of complex hydrocarbon and aqueous mixtures.

Our tool allows you to perform fluid characterization based on equations of state modeling, and also to match fluid properties with experimental data through robust regression algorithms.

This application is directly linked with a central database, so fluid composition and other experimental data can be directly read from it and simulation results stored back, all a transparent and streamlined process.

Equations of State (EoS)

 Estimate phase equilibrium through accurate cubic EoS.

  •   Peng-Robinson 78
  •   Soave-Redlich-Kwong

Heavier Components Characterization

Characterize your fluid with accurate models, extending C7+ fractions up to C80 or C200. Later, lump it into pseudo fractions in a way that optimizes your results.

Regression Module with PVT Experimental Data

To better represent your fluid, match the simulation model with your experimental data from the following typical PVT experiments:

  • Constant composition expansion
  • Differential liberation
  • Multi-stage separator tests

Phase Envelope

P-T phase diagrams based on the saturation points of the fluid.

Phase Equilibrium

  • Flash calculations up to 3 hydrocarbon phases
  • Phase equilibrium with aqueous phase
  • Huron-Vidal mixing rule to predict equilibrium with polar components
  • Isothermal and isobaric curve plot of phase properties

Phase Properties

Estimate the following volumetric, thermodynamic, and transport properties of each phase present in your system:

  •       Molar and mass fractions

Flow Assurance

Pipelines are subjected to several conditions of pressure and temperature along the way from the reservoir through to the surface. Along this process, the volume and properties of each phase in the system change, directly impacting the flow of these fluids within the pipelines.


Reservoir Characterization

Understanding how fluid behaves under reservoir conditions and through the pressure depletion process until the fluid reaches the surface is fundamental for predicting oil production volumes and timeframes. In this sense, the PVT analysis also provides insight into reservoir exploitation and recovery strategies, which can have a significant impact on a project’s cash flow and economic assessment.


Process Optimization

Design and optimization of processing facilities requires the knowledge of phase equilibrium and properties to maximize flow and mitigate the risk of flow assurance issues through the network.
