Difficult fluids stretch the capabilities of conventional design practices and have characteristics that make fluid production more challenging than normal. Genesis has tools, models and experience that make it simpler to manage difficult fluids. 

 

As oil and gas developments progress into deeper water and increasingly complex reservoir environments, challenging issues often arise.  

 

These can include combined gas hydrates and solidified oil or gels that form on shutdown, or asphaltene precipitation with produced water leading to stable emulsions and production loss.  

 

Changes in fluid characteristics can bring production loss and downtime, and even present a risk to the entire economics of the development. 

 

In the case of mercury, we possess validated tools to predict the partitioning and distribution of relevant phases, including liquid and solids. These tools can be used with a typical flowsheet simulator. 

 

For dense phase operation, including CO2 mixtures, we have validated equations of state and experience of working with flow assurance models that need to operate close to the mixture critical point during transients. 

 

Our world-class experience in the design and management of difficult fluids can allow clients to recognise where fluids will exhibit challenging behaviours, and how the risks to a project can be reduced. 

 

We combine detailed thermodynamic, flow assurance and process modelling to help clients understand the consequences of multiple and combined fluid challenges, and identify potential solutions. 

 

Our bespoke tools include: 

  • Mercury modelling and phase distribution 

  • Advanced equations of state CPA, SAFT and GERG for complex fluids, solids and dense phase operation. 

  • Hydrate melting models with pressure change and heating.
