Over the course of the four-week testing programme, Eden Geothermal will determine the productivity of the project's first drilled well
A four-week well testing programme for well EG-1 has started at the Eden Geothermal Project at Cornwall, UK. The programme will include performing injection and production tests to collect data about the well’s productivity.
Drilling of well EG-1 was completed in November 5, 2021, as we reported. With a vertical depth of 4,871 meters and a total length of 5,277 meters, EG-1 became the longest geothermal well drilled in the UK.
More recently, Eden Geothermal announced that construction of the heat main has started for the biomes, buildings, and greenhouses of the Eden Project. EG-1 will eventually be connected to this heat main, should the well be sufficiently productive.
The testing programme will consist of two phases – injection testing and production testing. These tests will help assess the permeability of the structures intersected by the well, as well as the downhole pressure and temperature of the production zones. The project team also anticipates that their seismic monitoring network will detect low-level seismicity during well testing.
