Hydrate Equilibrium Predictions

Presently, there are significant error margins built into deployment of thermodynamic inhibition systems. In some cases this can lead to a doubling of estimates for the required amount of MEG for full inhibition. Part of this comes from uncertainty surrounding hydrate equilibrium conditions – with secondary safety factors built in on top of these. As part of this project we are initially compiling all hydrate equilibrium data relevant to the subsea oil & gas industry, allowing us to compare, contrast, and identify reliable data sets. This is being incorporated into a tool which engineers can use to generate heuristics and quantify the uncertainty in hydrate equilibrium predictions for their system. Overall, this is expected to add confidence in the design stage, allowing for a reduction in unnecessary over-dosing and resulting in cost savings.
