Hello Lucky,

That's the one. Great if we can get in on that.

Part of a DGD post

" The drilling tool of the RNS in my opinion can only be a mud motor which is a positive displacement tool where the pumped fluid causes the shaft with the drill bit to rotate. The stator of the motor is made with a substantial amount of elastomer which seals against the rotor. Problems happen when the elastomer breaks apart due to overtorque by stalling and heat build up in the lobes. When the elastomer fails, the motor has to be pulled back to surface and changed. With the addition of graphene to the elastomer, it should increase the power capability (faster drilling rate) and probably help the heat dissipate better (more reliable). The deeper the well, the more hostile the environment - the Oil operator will demand the best stator and be willing to pay over the odds to make sure it drills faster and be more reliable. This is a great application and the innovator wants to keep it secret as long as possible while being able to charge a premium before the competition gets wind."

Ta

Should have looked myself but I'm reading through up some graphene enhanced 'stuff' on the web.

Hello Super,

No experience at all.

Like you say, I know somebody on board was an expert.

Maybe do a search for anybody who talked about 'mud motors' or

'oil and gas' or something?

[superg1] 12/1/2020 18:52

Lag

Are you the oil experience guy, I was trying to think who posted. I binned the stator a while back, working through a list and finding some interesting stuff.

Evening John,

Well now I know (roughly) how they drill a 'bent' hole !

As I see it I understand what the stator is now and why making it stonger helps.

Thinking a bit more, I guess friction between the screw like stator and rotor
makes heat (as well as what is down the hole already) so I wonder if nanene
in the mud would help conduct the heat away and maybe lubricate as well allowing extra torque?

All great stuff (black stuff..) hopefully, lots of black stuff !

[superg1] 12/1/2020 18:24

Hmmm

Not very often these days that some post some seriously interesting points.

I had been making progress but hadn’t appreciated the extent.

I’ll say no more for now.

laginaneil, bobsworth and anyone else wondering what the 'downhole drilling tool' is take a look at this.



I am NOT suggesting that Dynadrill is the company involved, this merely illustrates the technology I think this Oil & Gas application is all about.

The ability of the stator elastomer to survive in high temperatures without failing is the issue. The geometry of the stator and rotor determine the speed of the motor for any given flow rate and the torque generated at the bit is, more or less, directly proportional to the differential pressure across the motor power section. High power comes with high torque and high torques places high loads on the stator lobes which break down earlier at high temperatures. Adding graphene would make the stator stronger and conduct heat away faster enabling the motor to be used in more demanding downhole environments.

Hi laginaneil

Yes your right, it looks like graphene has different applications in oil & gas industry. Polymer Seals is big business too especially in USA with all the fracking going on.

Here are some headlines to show the size of this growing market

Oil & Gas Processing Seals Market To Reach USD 6.74 Billion By 2026 | Reports And Data
Oil & Gas Processing Seals Market Size – USD 5.57 Billion in 2018, Market Growth - CAGR of 2.3%, Oil & Gas Processing Seals Industry Trends – The increasing production of shale gas.

Hello Bobsworth,

I think the one they are working on is some kind of polymer seal.

However, I seem to remember some time wayback before the O&G 12Kg deal

an 'anticorrosion' colaboration.

I also find the words in the patent you highlighted before, talking about

analysis of the liquid with graphene in it that comes back up the hole

to tell them things about what goes on down the hole, implies putting it in

some liquid to pump down the hole, as another application.

I think they can see a lot of uses for our 'black gold' !

Roll on baby !!

Got to share this one too, last one, they are bloody huge and what a lovely thing to do.

"Apparently wombats in fire effected areas are not only allowing other animals to take shelter in their deep, fire-resistant burrows but are actively herding fleeing animals into them.

We’re seeing more leadership and empathy from these guys than the entire Federal government."

[1teepee] 12/1/2020 13:53

You feeling ironic recently ? You put out very mixed signals

[hattie1] 12/1/2020 13:37

Well said Lucky we are so blessed to live here in the UK

[luckyorange] 12/1/2020 13:25

Just an o/t on what really matters in the world out there instead of focussing on the pathetic ones on here, look at this

"They know the Iranian regime has just slaughtered 1,500 protesters & they’re protesting. This is courage."




For those that don't use twitter they are chanting

“Soleimani was a murderer, his Leader is also a murderer!”
“Soleimani was a murderer, his Leader is also a murderer!”
“Soleimani was a murderer, his Leader is also a murderer!”
“Soleimani was a murderer, his Leader is also a murderer!”

Bravest people in the world.

✈️ Airbus ✈️

Elmar Bonaccurso, Senior Scientist and Project Manager for Surface Technology at Airbus, says: "Airbus has been following the Graphene Flagship from the beginning. Now, after six years of successful research and development, we are at the right point to step in with a larger project. We expect that, by using graphene as a material for ice protection systems, we can reduce the complexity of these systems to create a system that uses less energy, reduces fuel consumption and allows us to become more environmentally friendly in aviation."🚀

I don't really care Andy about anything he says to be honest and certainly won't pay to see his rubbish, enough of him, that makes him important, he isn't and his views on anything are inconsequential and have no impact anywhere although he would like PI's to think otherwise.

What I am more interested in however is the sudden huge interest in Versarien worldwide, could it be because they produce the best quality graphene out there and others want it or the company?

They are certainly at the top of the list as the Graphene Flagship/Airbus testing has proven , doubt if anyone else in Europe applied for the GICE spec , if they did then they were turned away. That spec seemed to be written for Versarien as they were the only company that could meet the criteria in Europe, haven't seen anyone complaining about them being given the contract anyway?

Seen something else that has VRS written all over it too but from a different angle, keep looking.
