Project Description
In Pijnacker, the Netherlands, several agricultural companies signed for a collaboration of the development of geothermal energy for heating their greenhouses. After the completion of the wells at Ammerlaan, the rig moved to the neighbor “Tomato nursery Gebr. Duijvestijn”. WEP/PGMi was again responsible for the geological aspects, well design and drilling supervision for this geothermal doublet with deviated wells to a vertical depth of 2300 meters and more than 3000 meters AH. During the test, the geothermal well produced 130 m3 / hour with a temperature of 68 degrees Celsius.
