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 […]

Community projects benefit from Eden Geothermal grants

Nine groups based near the Eden Project have been awarded grants from the Eden Geothermal Community Fund for projects that benefit local people and improve the environment or community facilities. The £20,000 fund was launched in November last year, with applications received for a wide variety of projects across Treverbyn, Carlyon, St Blaise and Luxulyan […]

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 […]

Great new ‘Fully Charged’ film about Eden Geothermal

We loved meeting Robert Llewellyn (better known to some as ‘Kryten from Red Dwarf’) when he visited Eden Geothermal to make a film for the Fully Charged clean energy channel. A great in-depth look at our project and the potential of geothermal more widely – not to mention an insider’s view of operations on the […]

Drilling of 17 1/2″ section of EG-1 completed at 1510m section TD

Another milestone reached today, as we completed drilling the 17 ½” section of EG-1 at 1510m section TD, and are now preparing to run casing. This week’s geology sample from our wellsite geologists at GeoScience Ltd comes from 1385m MD, where we encountered some interesting mineralogy, including this Jasper specimen. Usually considered as impure chalcedony, […]

Drilling update 30/06/21

This morning, drilling at EG-1, our first well beneath the Eden Project, reached 1266m MD. This week’s geology sample was taken at 1200m MD and shows a typical example of altered granite, with kaolinite and chlorite alteration.

We’ve drilled past 1000m

Today (at 14.24, to be precise) EG-1 reached 1000m MD (measured depth). So we’re as deep as the ‘Queen of Cornish mines’, Dolcoath, near Camborne. At 550 fathoms (3300 feet or 1005m), the Williams shaft was reputedly the deepest mine in the world for a time, and is still the deepest in Cornwall. The shaft […]

EG-1 reaches 823m MD

We continue to make sure and steady progress, and this morning (15th June) EG-1 had been drilled to 823m MD. This sample was taken from 640m MD, just as we entered an interesting zone of fracturing. It shows plenty of accessory minerals, including some stunning tourmalines and free manganese grains. Thank you to our wellsite […]

Update at 500m MD – 08/06/21

Today we’ve reached 500m MD with EG-1, our first well at the Eden Project! Pictured is a sample taken at 170m MD (measured depth) and provided by our wellsite geology friends at GeoScience Ltd. This is one of our favourites from the first well section, and stands out because of its pink/red colour. The colour […]
