Katherine Roe, CEO at Wentworth Resources talks through the Ruvuma gas development in Tanzania. Watch the full video here.
Probably a stupid question as different tools will have different diameters..plus logging tools were run to karoo
Anyway Q series was design by boart longyear, in 1953 the company applied for a patent on the first wireline core retrieval system–the Q™ Wireline System
https://app.boartlongyear.com/brochures/Reference%202018_2(Web).pdf
After setting conductor casing they drilled to 400m PQ(5" hole), cased.
So HQ(4") next to TD I guess..
Then sidetracked and cased, so I would guess NQ 3" to bottom??...
Until tonight I thought Q series wireline rods were related to wireline logging tools, so logging as you go. ultra slim logging tools.. Mmmm, not sure now, so if the bore hole is too small???
Does anybody know the minimum hole size for logging tools ?
I dont think thats quite how it works, there seems to be relationship width to depth..
DM did say it could drill an 8 1/2" hole to 2500m, I believe 7" casing fits in that size hole...
From that I got the idea 7" casing to 2500m???
But I read a paper saying the rig could only run 9 5/8" production casing to 1100m,
After you run your 9 5/8" casing, you drill the 8 1/2" hole, then run your 7" casing.
I doubt it will be to 2500m but I dont really know
@AP, have you seen what casings can be run to what depth ?
The rig has been designed for drilling the top section of holes, which are then completed by another rig.
It can also complete shallow wells, can drill a hole to 2400m, can run casing X to ? and casing Y to?
@AP, I get the impression from this article, Top hole Drilling, 427m hole drilling time 13 hours, drill 1 day move the next... page 7

Drilling in India, 400m in 18hrs article
https://magazines.miningandconstruction.com/sites/magazines.miningandconstruction.com/files/magazine/2017-01/dhd15-1.pdf
@AP, MMMMmmm How about the other extreme 400m in 18hrs.......
It was a tough drill, so was just showing how it outperformed a 2000HP Tower..

I calculated 16hrs/day from some other numbers..
So 400m in 18hrs article to get you excited from Deep Hole Driller Magazine, Epiroc

Some drilling stats,, Predator 950hp v Tower 2000hp
I Assume same pad...
Tower, MW08 378 m in 27 days (Average rate of penetration of 14 m/day)
Predator, MW08A 360 m in 17 days (Average rate of penetration of 21.18 m/day);
Cluffs Predator was contracted to drill 20 wells in Kenya for $41m.
Cluffs drilling partner was Great Rift Drilling, looks like these were the drilling contractors,
Drilling stopped due unpaid invoices, so thats why only 8 holes were drilled
Drilling stopped in 2015...
DD, no other dodgy shares but have a couple in my watch list, with transformational assets, and issues like money, access and hygiene, dusters I believe...
@Heliumbull,
Now, a research group from Oxford and Durham universities, working with Norway-headquartered helium exploration company Helium One

https://physicsworld.com/a/on-the-hunt-for-helium/
@DD13, here is a wild card for you..
Cluff like green energy, Geothermal stuff.. Exploration to Development
A Helium Pure Play project would look nice in their portfolio, ?
Maybe it will be them who puts the pieces together for this years drill
@DD13, lol, Now DM said Rig X could drill a hole 8 1/2" to 2500m, he did'nt say without washing out ;)
Could be thats not our rig
Anyway who needs EU funding, the Chinese love Africa and Drilling thats why Noble have a Chinese Geo company.. ;)
Epiroc Predator Kenya
Could it have be taken by Epiroc operators contracted to Cluff
https://epiroc.scene7.com/is/image/epiroc/Predator+in+Kenya?$landscape400$
I also read a comment which said Cluff owned the rig, but that was'nt from cluff..
Cluff(2020) are in the planning phase of 150mw Geo Project in Fantale but I cant find depths of wells and production casings to see if they are beyond the abilities of the rig. (reason for sale)
The limited use in Kenya, just 8 holes out of 42,..
One article said it was a top holing rig, preparing anchor casing, so wonder why only 8 holes.
Top holing because I believe limited by its ability to drill depth and run required production casing to depth...
Another said it was used to drill the shallower wells in the caldera, the other wells to deep...
But I read the big drills struggled, lots of down time due to stuck bits..
Looks like that rig was used for top holing the Geothermal wells in Menengai from about 2013.
Drilling down 400-500m to run the anchor casing.
The only top holing rig
The anchor supports the BOP, so doubt the rig comes with BOP
A 2022 article suggested 43 wells had been drilled,
so it was a busy rig if it top holed all but with just 5000hours, doubt it
Cluff
Their website has single photo showing a predator rig sitting at a volcanoes caldera, but their current Geothermal prospecting area is outside of Awash National Park, Mount Fantale Volcano, so I believe its a photo from elsewhere, maybe the Menengai Caldera in Kenya, back from 2014/15..Another of their projects..
http://www.travelinggeologist.com/2015/01/menengai-caldera-in-kenya-with-helen-robinson/
Unlike the Jeff Weber listed rig for sale, interestingly this rig(same hours as on JW) for sale uses the same photo, and a couple more that look from the same site, so not from a brochure..
https://www.drillingsupplieseurope.com/product/atlas-copco-predator/
looks like Cluff offer lots of services,
"Hotspur Geothermal has relationships across the geothermal industry globally through academic institutions, drilling contractors, vendors, financial institutions, and government bodies."
Could be Cluff are that 3rd party, or arranged.
If too many Post like they have lost hope the sp will be rotten, and johnny will be picking up cheap shares for the next news, pump or hopefully the drill..
If your going to cut your loses you will get a little more if people think its worth a punt..
So is i t a world class asset waiting to be proven, with a team at identified rig , rig preparations likely to be in hand, money in the bank ready to sign contracts, and a drilling window into November possibly early December .
Or Its unproven world class asset , we have no drill, money is slowly running out, and its going to rain for Christmas..
Either way, drill or no drill, one will keep a better price than the other..
Liberum’s ‘buy’ note contained a 19p price target. The price target incorporates the broker’s belief that Helium One has a 35% chance of geological success, it said, but was not afraid to suggest 54p would be attainable if success was certain.
Anyone seen the note, to see how they come to 54p, ?
