The latest Investing Matters Podcast episode featuring Jeremy Skillington, CEO of Poolbeg Pharma has just been released. Listen here.
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 !!
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
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
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
