The deep drilling work was begun in November 2018 and is now complete with the injection well reach over 2,000m and the production well going to a depth in excess of 5,000m. Both wells intersected the fault at the predicted depth and the temperature at the bottom of the deeper well is around 190C, which is also as expected.

Downhole measurements have confirmed that there are lots of natural fractures and early indications are that the permeability is promising.

Geothermal Engineering Limited is now ready to begin the evaluation stage of the project. During this stage, a series of measurements and hydraulic tests to evaluate the fault structure will be undertaken to make sure the wells are in good condition, and to evaluate the amount of geothermal energy that can be sustainably harnessed.

At the start of September, the first part of this work will begin with the removal of a temporary downhole packer from UD-1. This will allow the onsite team to carry out some more downhole ‘logging' measurements and attempt to collect some sidewall cores.
