Production Chemistry and Fluid Characterisation

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
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.
