In for 6k worths - as much as my wife will not find as missing. I worked in neighboring Brunei offshore for SHELL many years ago - shed loads of hydrocarbons

My gravestone will read : I always told you I was ill

As per the last RNS, I did expect another one saying TD is reached, rigging up for wireline. The tweet - ápproaching TD' suggests at the most 1-2 days away BWTFDIK

Sandstone can be a pain in the bum to drill - can be unstable

Drilling through any faults can also be very challenging…..

Quartz is a mineral - not a rock

Sand is basically quartz

Sandstone is sand in a cement matrix

There are a number of situations where ROP is deliberately controlled:

- Where there is MWD - measurement while drilling tools in the hole and a controlled ROP gives better data

- Hole cleaning issues - slower ROP will give better hole cleaning and lower ECD - Equivalent Circulating density

- Picking a casing or logging point

- I doubt it is any of the above in this case

I'm with Joe on this one. Drilling is not straight forward with many challenges. Stuck pipe, lost pipe, heavy losses, well instability. Is there an issue - maybe, maybe not. Could just be a delay in reporting while the NOMAD verifies the RNS. But could there be significant issues - for sure !!

Need to wireline it before running casing.

Could well be an old photo. Hard to tell the casing size - could well be the 13-3/8 casing from the previous section. Looks like they are picking it up to the rig floor - if they were drilling they would not and could not do that - so my money is on an old photo. They can only pick it up when there is no string in the hole ie not whilst drilling

I am a mud engineer, and have worked in Africa for the last 8 years. Currently offshore Ivory Coast. I have developed some contacts over this time. I pushed him on Helium shows - but he dodged that question very well ! So not exactly a mind blowing update from me - but I tried

Many reasons it slows down - harder formation at greater depth, potential for a bit trip, MWD failure - need to change out tool. ROP is never at the same rate. Such is the drilling game

Still drilling apparently - cannot reveal source - but I have a contact who is a manager for one of the service companies

Agreed - quick wiper trip to make sure hole is slick, then wireline

Casing is hung off the wellhead - depending on which section, all or a proportion of the casing/wellbore annulus is cemented. If there was no cement it would still be suspended by the wellhead and assisted by the buoyancy of the drilling fluid

Cement has to be mixed relatively quickly - there is a quite a short thickening time, so they cannot be messing around with bulk bags. Mix and pump ASAP or risk cementing up batch mixer

Very unlikely they ship out cement in Bulk Bags. It will come in trucks in the powder form. Mixed on site, most likely in a cement batch mixer and pumped by the cement unit

I am sure your mum never said that to your face......

Regarding storage, best practice on a land job would be to store in a container - all depends if they have enough and have planned it properly. The sacked chemicals, especially polymers and caustic that are hydroscopic should 100% be stored in the dry. Large Bulk bags like salt, will be double wrapped so can be stored outside, but never ideal

Being a mud engineer myself, I would guess those white bulk bags are some form of salt - either KCl, NaCl, CaCl2 - used as inhibiting clay swelling in water based muds. Could also be Calcium Carbonate - used as a bridging agent to add the wellbore integrity and strength - particularly in sandstones. The bulk bags are too big to be barite

Barite is a mineral - yes. But it is used as the primary weighting agent in many water based and oil based muds. Does not add anything to lubricity.

Dai2belts- wells do not always go to plan - so there is no way that they will go from running 13-3/8 casing and miss out the 12-1/4 section. What is they miss it out and there is an issue in the 8-1/2 section and they have to run casing and then drill say a 6 inch section with smaller BHA etc that they probably do not have. Also better to run logs in a bigger wellbore
