Possible formation pressure = be prepared.

Drilling into a pressured formation without a contingency plan is madness.

It could be gas. It could be water. It could be a bit of both. ⚠️

Keithy from our team puts it simply.

Say a driller hits artesian flow and water is pushing out of the collar or casing.

First job is working out how much pressure is driving that water out of the hole.

That number tells you how much weight your fluid needs to hold the formation back.

This is called drilling overbalanced. Your fluid column pushes harder on the formation than the formation pushes on the hole.

Throwback to some clips from Dave's archive.

A little bit back in the day in the muds game.

Tujuh Bukit, Java.

Deep in the jungle.

No roads. Just a beaten path and some exploration drilling.

These were captured on an old camera and they're a ripper reminder of how far the drilling industry has come.

Then again, some sites out there still look a lot like this aroun the globe.

Either way, it's pretty cool to step back and see where things have started

Thanks for dusting these off, Dave.

Air Drilling with swelling clays?

Michael Kokins breaks down one of the ways to combat this in the clip.

Clay only reacts once. It gets attracted to water, attaches to it and swells. Once that starts, there's no going back.

Air drillers work hard to keep the hole dry. But the deeper you go, the more the hole naturally produces humidity. If the clay is reactive enough, that humidity is all it needs.

The fix is simple. Get something onto the clay before the water does.

That's where KCL (potassium chloride) comes in. It's easy to get and easy to mix.

If you know you're heading into swelling clay, lace your water with KCL. Drill the section dry, then pull back and spray the formation with the KCL water. Let it soak in and it switches the clay off, so it won't swell after that.

The catch is that you have to commit to it. It's a small step in an air drilling program that can save a lot of headaches down the track.

Not every oil belongs down a hammer.

Dave Williams and John Mellor from Mincon to talk about something that gets overlooked on site.

Mincon builds to incredibly tight tolerances. The right oil is what keeps those tolerances intact for the life of the tool.

Pouring in whatever is on hand might save a few dollars today. It usually costs a lot more down the track.

The full conversation is in the video.

Cheers Heinrich Hoops for shooting this one.

Your drilling fluid is meant to come back up the hole.
Lost circulation is what happens when it decides not to.

This one is a rapid fire hot seat question for Peter Quinn giving us a straight forward run down.

Why does fluid go missing?
Open zones in the formation. Fractures, cavities, voids.

Fluid likes the path of least resistance. In a firm, perfect world hole… that means up the annulus and out.
In a loss zone, the fluid instead makes its way into the formation, partially, or totally.

What that looks like on the rig:

You lose the support of a full fluid column, so torque is harder to keep down.
Rod chatter shows up.
Mud costs climb because you cannot recirculate.
And you are left guessing what is actually coming out of the hole.

So how do you stop it?

There is no single size or type of lost circulation material that works every time.

A good rule of thumb is to run a blend.
Multiple types of material.
Multiple sizes of material.

That gives you a better chance of bridging the different sized openings you cannot see.

Dave's bags are packed and he's off to the Egypt Mining Forum.

Not a bad part of the world to be heading to for work

It'll be a good chance to catch up with some of our clients out that way and get a proper look at what's happening in the region. Mining activity, drilling challenges, where things are headed.

Always good to see it firsthand rather than just hear about it secondhand.

We reckon there's a fair bit of opportunity in that part of the world and we're keen to understand how Mudex can support drilling operations out there, whether that's our fluids, technical support or just having a proper conversation about what teams on the ground actually need.

If you're going to be at the forum and want to grab a coffee and say gday, flick him a message. Dave's always up for a chat.

Spotted these two out in the field on a WA site this week.

VIS PAC R and Poly Vis Liquid, doing exactly what they're meant to do on a water well job.

No fuss, no drama, just steady performance day in and day out.

It's easy to talk about drilling fluids in a lab or on a spec sheet.

It's another thing entirely to see them holding up hole, keeping viscosity where it needs to be, and making life easier for the crew running the rig.

Together they're doing the quiet, unglamorous work that keeps a project on track.

That's the bit we love seeing. Not the marketing shot, the actual product out in the wild, doing the job it was built for.

Happy Wednesday from the Mudex team. If your rig is running one of ours right now, we'd love to hear how it's performing.

Adelaide, mark your calendars for tomorrow!

Keith Arnett and Peter Quinn are packing their bags for DRILL26, hosted by ADIA at the Adelaide Convention Centre, 22-24 September.

This year's theme is Mission Critical, which feels about right. Drilling keeps the resources, energy and infrastructure sectors moving, and events like this are where some real chats go down.

Not the polished pitch conversations either. The ones about what is actually working on your rigs right now, what is giving you grief, and what you wish someone would just fix already.

If you are heading to DRILL26, come find Keith and Peter. Grab a coffee, talk shop. That is genuinely what they are there for.

No pitch decks required. Just two blokes who know their muds and like talking to the people using them.

See you in Adelaide.

We threw a rapid-fire question at John about Geo Bond 2.0.

Here's what he said.

John has worked across a few different companies and used a lot of products over his time in the drilling industry.

His take on Geo Bond 2.0?

"It's one of the best all-in-one sort of products I've ever used."

What actually makes it stand out is the microparticles and micro polymers inside it.

They form a latticework, not just around the core like a lot of competing products claim to do, but around the borehole wall itself as well.

That means you're getting viscosity AND hole stabilisation from a single product.

Other products out there will tick one of those boxes.

Geo Bond 2.0 ticks both. And it also helps manage lost circulation on top of that.

It's not marketed as an all-in-one.

But out in the field, that's exactly what it acts like.

If you're carrying multiple products to do what one could handle, it might be worth a conversation.

Reach out to the Mudex team and ask about Geo Bond 2.0. 👇

If your mud stinks, That's bacteria. And it's eating your mud.

Here's what's actually happening.

PAC aka polyanionic cellulose..... is a polysaccharide. Essentially a sugar-based polymer. And bacteria love a bit of sugar.

So the more PAC you're running, the more food you're handing to any bacterial contamination in your system.

The two classic signs to watch for:

1. The mud smells off. That rotten, swampy odour is a red flag.
2. Your viscosity starts dropping for no obvious reason. That's the bacteria consuming your polymer chain.

And here's where it gets tricky.

It's not just sitting in your pit. Bacterial contamination gets into the borehole, into fractures, into zones downhole that are very hard to flush out once it takes hold.

Some people reach for chlorine. It will kill the bacteria — but it'll also burn out every polymer in your system at the same time. Not a trade-off worth making.

Biocide is the better call. Targeted, effective, and won't wreck everything else you've built into the mud.

so this is a little snippet grabbed out of a much wider chat but you get the gist!
