Ever looked at a massive 18-wheeler hauling specialized gear through the Texas scrub and wondered what the name on the side actually does? If you've lived in Houston or the Permian Basin, you’ve seen the red logo. Honestly, most people think Halliburton Company is just a "drilling company." Or maybe they remember the political headlines from twenty years ago.
But if you ask anyone actually working the rigs in 2026, they’ll tell you something different. Halliburton doesn’t usually own the oil. They don't own the gas. They are the high-tech pit crew for the world’s biggest energy giants. Basically, they provide the "brains and brawn" to get the stuff out of the ground.
What Halliburton Company Does (The Big Picture)
At its core, Halliburton is an oilfield services company. Think of them as the ultimate contractor. If ExxonMobil or a national oil company like Saudi Aramco wants to find oil, they call Halliburton. When they need to drill a five-mile-deep hole and then turn it sideways with pinpoint accuracy, Halliburton’s tech is usually what’s making it happen.
They’ve split their massive empire into two main buckets. It's kinda technical, but it helps to see where the money comes from.
1. Completion and Production (The "Brawn")
This is their biggest moneymaker. In early 2025, this segment alone was pulling in over $3 billion a quarter. It’s the heavy-lifting side of the business.

- Cementing: This sounds boring, but it’s actually life-or-death. They pump special cement down into the well to seal it off. It keeps the oil in the pipe and the groundwater safe. Erle P. Halliburton actually started the company back in 1919 doing exactly this.
- Fracking: You’ve heard the term. Halliburton is a titan here. They use massive pumps (like their Zeus IQ platform) to crack open rock and let the gas flow.
- Artificial Lift: Eventually, a well loses its natural pressure. Halliburton installs pumps—some of them are giant electric ones deep underground—to keep the oil flowing when it doesn't want to come up on its own.
2. Drilling and Evaluation (The "Brains")
This side is all about data. They use sensors and software to "see" through miles of solid rock.
- Logging while drilling: They have tools that send back real-time data while the bit is turning. It tells the operator exactly what kind of rock they’re hitting.
- Digital Twins: They’ve gone all-in on software. They create 3D digital versions of the reservoir to predict how it will behave over the next twenty years.
- Drilling Fluids: They don’t just use water. They use complex chemical "muds" (managed by their Baroid brand) to keep the drill bit cool and prevent the well from collapsing.
The 2026 Reality: Digital and Green?
You might be surprised to learn that Halliburton is currently trying to be a tech company. No, really.
By the start of 2026, they’ve started talking less about iron and more about "closed-loop automation." Their LOGIX system basically lets a computer steer the drill bit. It makes decisions thousands of times per second. A human just can't keep up with that.
They’re also quietly moving into things that aren't oil. They’ve recently signed deals to provide modular natural gas power for data centers. Why? Because AI needs a ton of power, and Halliburton knows how to manage gas power systems better than almost anyone. Plus, they’re working on Carbon Capture (CCS) and even Direct Lithium Extraction. If you want batteries for your EV, you need lithium, and the process of getting it looks a lot like... well, an oil well.
Why Do They Stay in the Headlines?
Halliburton is a lightning rod. Because they work for national governments and handle massive infrastructure, they get caught in the middle of geopolitics. In 2026, everyone is watching their moves in places like Venezuela and the Middle East.
They’re also facing a "higher-for-longer" interest rate environment. This means they’ve had to get really disciplined with their cash. In fact, for 2026, they’ve planned to slash their capital spending by about 30% to roughly $1 billion. They’d rather give that money back to shareholders than build a bunch of new equipment they might not need if oil prices dip.
What Most People Get Wrong
The biggest misconception is that Halliburton is a "driller." They usually don't own the drilling rigs. Companies like Nabors or Helmerich & Payne own the big metal towers. Halliburton provides the services that go down the hole.

Another one? That they’re "stuck in the past."
Actually, they’re one of the largest industrial software companies you’ve never heard of. Their Landmark division creates the software that most of the industry uses to map out the earth's crust. Without that code, the industry would basically be guessing where to poke holes.
Actionable Insights: How to Track Them
If you're looking at Halliburton as an investor or just an industry observer, here’s what actually matters right now:

- The "FCF" Number: Watch their Free Cash Flow. That’s the metric CEO Jeff Miller is obsessed with lately. If that’s high, the stock usually does well.
- International vs. North America: They are leaning hard into international markets (like Brazil and Saudi Arabia) because the U.S. shale market is getting a bit crowded and flat.
- The Tech Pivot: Look for mentions of "SmartWell" or "ZEUS IQ." This is high-margin stuff. The more they sell software and automation, the less they have to worry about the price of steel and trucks.
Keep an eye on their quarterly earnings reports, specifically the "Drilling and Evaluation" margins. When those go up, it means their high-tech bets are paying off. If you’re following the energy transition, watch their "Halliburton Labs" initiatives—that's where they hide the cool startup tech they're testing for the future.
