Greenhouse Geopower used Well Engineering Partners’ geothermal well design and project management services for its geothermal doublet in the greenhouse area Koekoekspolder in IJselmuiden, the Netherlands. Koekoekspolder is a greenhouse area containing modern greenhouses which are focused on environmentally friendly production of vegetables, e.g. tomatoes, cucumbers and paprika’s. The total area of the greenhouses together is approximately 100 ha. The two deviated wells, with a vertical depth of 1975m and 1823m, are used for generating safe, sustainable and environmentally friendly energy for heating these greenhouses. The joint venture of IF technology and well engineering partners (IF-WEP) provided the independent drilling management for Greenhouse Geopower. This joint venture was also responsible for the QHSE on the drilling site and verifying the work of the drilling contractor. The drilling went successful, and good temperatures of max 73°C were recorded during the welltest.
