The drilling of the first well of the United Downs Deep Geothermal Project is progressing well having reached depth of 1,645m and has indicated that due to the current performance, it will be the production well for the planned geothermal plant.
The United Downs Deep Geothermal Project in Cornwall, UK is progressing well on the drilling of its first well. After now having reviewed the drilling performance to date, and the geological information from cuttings, the developer has decided that the first well will now be the production well.
The drilling has reached a depth of 1,645 metres, as reported today. The target depth is around 4,500m.
According to the statement on its website, this first well is the more important well of the two as it will provide crucial information about the geology and temperature at our target depth, and it is imperative that we complete it as soon as possible.
The group will continue drilling UD-1 at a diameter of 12 ¼” to a depth of about 4,000m and then run the last of the three casing strings. Then the well will be finished at a diameter of 8 ½” before running geophysical logs and carrying out a short period of testing. This should be completed by the end of March, after that it is expected to skid the rig and begin drilling the second well UD-2.
