Production Chemistry and Fluid Characterisation

Scroll down for more

Fluids characterisation and production chemistry from Genesis encompasses a wide range of simulation and modelling techniques, which aim to replicate the realistic behaviour of the production fluids. During this process, experimental data is used to tune the physical properties of the fluids and generate corresponding simulated pseudo components. 

To minimise development risk, we must understand the challenges associated with production fluids. Production fluid issues range from characterisation to represent realistic phase behaviour, through to complex production chemistry interactions, such as wax, hydrates, gels and asphaltenes. 

We have extensive experience in a wide range of characterisation and production chemistry assessment techniques, which have been successfully used to address unique and varied challenges, such as: 

  • Equation of state matching and non-linear regression for optimised fluid characterisations and accurate PVT (Pressure Volume Temperature) behaviour prediction 

  • Dense phase equations of state with high accuracy close to the critical point and for derivative properties like speed of sound 

  • Characterisation of heavy oils, unconventional fluids and heavily mud contaminated fluid samples 

  • Numerical mud cleaning 

  • Emulsion modelling   

  • Non-Newtonian flow modelling  

  • Accurate characterisation of multiple, dissimilar fluid samples and minimisation of computational burden 

  • Precipitation of waxes, asphaltenes and other solids 

  • Modelling of Hydrate management, including the use of thermodynamic inhibitors, such as MEG, methanol and kinetic inhibitors and interactions with dissolved solids and production salts 

  • Use of SAFT and CPA equations of state for accurate hydrate modelling in the presence of polar fluids and electrolytes 

  • Hydrate, wax and gel interactions and transient modelling of plug melting kinetics using proprietary in-house techniques 

  • Advanced equation of state modelling and complex hydrocarbon interactions with unconventional injection fluids, such as carbon dioxide and polymers.
