Ezhik, showing the drill pipes might be a clue that they are preparing to run the wiper trip. If so, the casing is probably already in place after one week since the rig was up. Anyway, 7-10 days they said.

Don't forget they have to do a number of tests on the cement job, including logging, formation tests and pressure tests.

Things can change very fast here. There will be news about two drill rigs available again soon, maybe drilling Ingomar and Rudyard at the same time.

I would imagine the rig booked for Rudyard will be available again soon too.

The surface casing is already in place and cemented probably down to about 1000ft or so using 9" and 8" casing. They will need to put the drill bit in again and add 7" casing to below the unstable shale section to block it off. Sounds simple, but hopefully the lower sections are ok.

NewboF, so the plan was to send the rig off once drilled to TD. The next task was supposed to be to drop the wire line logger down and gather the data, but they couldn't do that after the cave in happened.

Tiburn, your summary is not quite correct. Bo said in an recent interview the first rig used at Ingomar would be doing 2 jobs elsewhere before returning to Rudyard. So, probably in 6 - 8 weeks from now .

Of course he is going to say that. But casing off unstable sections is never a simple matter whatever he says, and if I had a £1 for every time I heard this from a respected CEO and or Chairman I would be very wealthy. Let's hope they get lucky.

There are plenty of risks when reentering a well bore to add casing strings down to 2500 m and cementing them in place. Until the production casing is securely in place many things can go wrong. This shale collapse happened when they pulled the drill bit out, which means they didn't get the chance to add more casing strings and cement them. Will it happen again? It could.

The cost saving in days is from all work involved, but the drill rig charges are per depth drilled as far as I know. So maybe they saved 17 days operational costs.

Djm1, What? A second drill rig costs extra money. About £1,000,000. They do have enough cash to cover Rudyard too though.

Steve, take into account they are already over the original budget. It comes down to money.

I know. I'm just saying the reason for continuing down the hole with the drill bit is to clear it, not to extend it. I agree it would be an opportunity to extend the hole, but I don't think that's the plan. In any event casing off unstable ground and clearing the well bore isn't as simple as it sounds no matter what anyone says.

From the latest interview, it looks like after the shallow Mowry shale is cased off the drill will continue down the hole to clear it, so they can get the wire line logger down. Production casing comes after logging I believe.

No, the bigger rig is to deal with the casing. The way I understood Bo was they just need to block off the shale cave in. They already drilled past the flathead and I believe they want to log the 4 zones already drilled.

Who said "The bigger rig will allow them to find the full depth of the Cambrian pay zone also."? I think they are just going to put the drill bit in and drop a 7" casing down hoping not too much material drops down the well bore.

On 3 July 2023 China suddenly imposed restrictions on the exports of germanium (and gallium), ratcheting up trade tensions with Western allies. Invoking "national security interests," the Chinese Ministry of Commerce informed that companies that intend to sell products containing germanium would need an export licence. The products/compounds targeted are: germanium dioxide, germanium epitaxial growth substrate, germanium ingot, germanium metal, germanium tetrachloride and zinc germanium phosphide. It sees such products as "dual-use" items that may have military purposes and therefore warrant an extra layer of oversight.

NewboF, you don't need to be a helium expert to work out how oil and gas work.
