Reinjection in geothermal field
The Geothermal Institute has carried out a review of experience worldwide of reinjection in geothermal systems and complemented this with a modelling study to test ideas about where it is best to reinject: either infield close to the production wells or far away. The results show that infield reinjection should not be preferred for hot systems like Wairakei but is desirable for hot water systems where pressure support is required.
