We’re drilling our final 8 ½” section

Having successfully run and cemented casing in the 12¼” section of EG-1, we’re now into the final 8 ½” open hole section. The bits are grinding the granite to powder – as this cuttings sample from 4050m shows. Current depth is 4324m MD and we expect to intersect Great Crosscourse fault soon. The Eden Project […]

Geology helping drilling ahead

We’ve passed another milestone on our journey to the centre of the earth beneath the Eden Project – on Monday we drilled past the 2000m MD mark! As of 6am today, we’ve drilled to 2293m MD. The higher ROP (rate of penetration) achieved recently is due to the geology we’ve encountered: we’ve been able to […]

Project update 21st July 2021: faults, caves and ‘kicking off’

Casing and cementing our 17 ½“ well section went smoothly, and we’re now drilling the longest section of the well – the 12 ¼” diameter section. At 1706m MD, we “kicked off”: that is, we started drilling directionally, steering east on a trajectory designed to intersect with the Great Crosscourse fault. Now we’re in the […]

Groundworks complete and drilling to start soon at Eden Geothermal

After a year of intense activity, deep drilling is soon to commence at the pioneering Eden Geothermal Project near St Austell in Cornwall. Next week, the first lorries carrying a 450-tonne, 55 metre-high drilling rig will arrive on the outer edge of the Eden Project site, the home of the world-famous Rainforest and Mediterranean Biomes.
