Reduce CAPEX Costs
Problem Definition
Gas hydrates are one of the major flow assurance challenges for the industry and are expected wherever gas meets water at high pressure and low temperature. Operators typically mitigate the risk of hydrates by continuous injection of chemical inhibitors (methanol or MEG) or by investing in heated pipelines for large fields. These strategies are based on worst-case scenarios projected over life of field and are expensive to deploy requiring huge upfront CAPEX spend.
“Chemicals contaminate the production, which reduces the value of hydrocarbons produced. Because of this, operators spend a lot of money on removing inhibitors. You need infrastructure for the supply of inhibitor chemicals to the platform, which means increased CAPEX cost”

How We Solve It
Blue Gentoo has technology which can optimise the use of chemical inhibitors for hydrate mitigation or avoidance. This results in a significant reduction in the quantity of chemicals required to be injected and hence reduces the quantities required to be shipped, stored and recycled/regenerated. As a result the capital infrastructure needed on the facility can be smaller because of the lower volumes of chemicals required to be injected and treated.
Benefits
This will typically lead to a reduction in chemical inhibitor use of between 20% and 50% and so provides the potential for lower capital spend at the outset, because lower quantities of chemicals are required to be received, injected and recycled/regenerated over the life of the field.
