Hydrate Management - New understanding of hydrate phenomena in oil systems to enable safe operation within the hydrate zone

For the O&G industry, risk-based hydrate management can be a viable strategy for significantly widening the operational window. The traditional approach has been to avoid entering the hydrate region (high pressure and low temperature) altogether by temperature control (insulation and heating), chemicals (methanol and glycols) and pressure control. Although ensuring safe operations these remedies are costly for longer and colder transport conditions and not necessarily environmentally sound. This project will help meet demands of marginal field developments by advancing the new fundamental knowledge of gas hydrate properties and develop methods for risk assessment, minimize environmental impact and cost-effective hydrate management.

From field experience, it is known that some oil pipelines are easily plugged by gas hydrates while others are transportable. This is commonly accepted to be due to naturally occurring polar components in the crude oils. A main goal is to combine the increased resolution of mass spectrometry and advanced multivariate data analysis, block chain and machine learning to identify the hydrate-active components in crude oils.

Hydrate properties in terms of plugging risk and transport properties will be measured for a number of crude oil systems, and extraction of hydrates for analysis will be done at SINTEF Multiphase Flow Laboratory. Prediction tools will be developed, relating the structure of possible hydrate active components to the hydrate properties
