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.
Fluids characterisation and production chemistry at Genesis encompasses a wide range of simulation and modelling techniques, which aim to replicate 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.
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 behaviour prediction;
- Characterisation of heavy oils, unconventional fluids and heavily mud contaminated fluid samples;
- Accurate characterisation of multiple, dissimilar fluid samples and minimisation of computational burden;
- Precipitation of waxes, asphaltenes and other solids;
- Hydrate management, including the use of thermodynamic inhibitors, such as MEG, methanol and kinetic inhibitors and interactions with dissolved solids and production salts;
- 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.
