Project Description

To cope with corrosion issues without injection of corrosion inhibitor a detailed well design making use of corrosion-resistant materials is made. WEP assisted in the procurement of well materials which have all been ordered to date. Tendering for services is currently ongoing and reaching its final phase. Drilling of the two geothermal wells in Tinte in planned to start in December 2019 / January 2020 using the DrillTec Vario Rig.
