There isn't one correct way to buy Halliburton services. I know that's not a satisfying answer, but it's the truth.
I'm the procurement manager at a 140-person independent E&P company. I've managed a well services budget of about $18M per year since 2019, and I've negotiated with more than two dozen vendors across drilling, cementing, fracturing, and completion work. I've also built a cost tracking file that goes back six years, so I've sat through enough budget reviews to know what actually moves the number.
If you're trying to figure out exactly what to do with Halliburton PSLs, the Halliburton Agile Field Development approach, and whether the stock should influence your decision, here's my answer: it depends. This is a scenario-based guide, not a universal recommendation.
First, what are Halliburton PSLs?
A PSL is a Product Service Line. It's the label Halliburton uses for a group of related services: drilling fluids, cementing, fracturing, wireline, completion tools, production optimization, and so on. You don't need to memorize every PSL to be a good buyer. You do need to know that each service line carries its own cost structure, pricing pressure, and operational team.
That matters for one simple reason: a low quote in one PSL doesn't mean the total invoice will be low. The pumpdown price can be great, and then the perforating add-on can erase all of it. This has happened on our invoices more times than I'd like to count. Actually, I can count them—it's happened six times in the last two years.
When you're comparing Halliburton PSLs, compare the complete package per stage, not the individual unit rates. If a vendor knows you're watching total cost per completed stage, you'll get a very different set of numbers.
The Halliburton Agile Field Development Approach, Explained for Budget Owners
Agile field development isn't about skipping planning. It's about planning in smaller loops.
Instead of building one giant development plan and then sticking to it no matter what, the agile approach says: build a reasonable model, drill a small number of wells, feed real results back into the model, and adjust before the next pad. It's less glamorous than a big feasibility study, but it's a lot better at preventing sunk-cost disasters.
In Q2 2024, we ran a three-well pilot using this framework. The original full-field plan called for a certain completion design that would have made every stage look the same. After the first two wells, we had enough data to simplify and downsize the next program. We ended up avoiding about $2.1M in completions spend—without a single safety or production trade-off. That's not a magic trick. That's what happens when you leave room to change your mind.
From a cost controller's seat, the agile approach has one huge benefit: it puts decision points where data exists. You don't have to guess as far ahead. You still have to be disciplined about stopping an experiment that isn't working, but that's a different problem.
Where Monarch Fits, and Where It Doesn't
Monarch is the Halliburton planning platform that often shows up in conversations about agile delivery. On our side, we use Landmark Monarch to keep well plans, actual cost data, and revision history in one place.
What I like about Monarch isn't the interface. It's the audit trail. When a field engineer changes a planned stage count, Monarch keeps the previous version and the new version. There's a date and a name attached. That makes budget conversations less about 'he said, she said' and more about 'why did we add six stages in the middle of the night?' We did have that conversation once. It did not end well for the middle-of-the-night stage count.
But Monarch is a tool, not a strategy. If your team isn't prepared to use the data to change plans, you don't need the tool. The worst case is paying for a very organized way of doing the same thing you've always done.
Three Field Scenarios, Three Different Answers
Scenario 1: You're a large operator with an in-house planning team
If you have several full-time engineers who can model, review, and challenge Halliburton's recommendations, don't pay an extra integration premium for something you already provide. Get detailed PSL pricing and keep decision-making inside your team. You can still use Halliburton's agile field development tools, but you don't need Halliburton to run the workflow for you.
Scenario 2: You're a small operator with one or two technical people
This is where the counterintuitive part comes in. Buy more integration than you think you need, not less.
I've compared the two routes. On a typical four-well pad, the self-managed approach with separate drilling, cementing, and fracturing vendors looked cheaper on paper. But when I added up the coordination hours, the extra project management overhead, and the finger-pointing when a stage went sideways, the integrated package won. The point isn't loyalty to one service company. The point is that your one engineer shouldn't have to be a full-time contract administrator.
Scenario 3: You're new to a basin or new to unconventional development
Use the agile field development approach to buy information early. That's not a budget excuse; it's a budget plan.
The first two wells in a new basin are tuition. Everyone wants to optimize the tenth well before the first one is drilled. That's backwards. If you can keep the first program small and the data quality high, you'll save far more money on wells 4 through 20 than you could ever save on wells 1 through 3. Hire Halliburton's PSLs for what they know, but keep the decision loop short enough that you can act on what you learn.
Scenario 4: You're under pressure to cut costs
Don't compare day rates. Compare total cost per completed stage.
In Q3 2024, we reviewed one of our assets where the 'cheap' vendor had a slightly lower stage price. But their support team was slower, the failures required more redrills, and the cleanup cost ate the savings. The total cost per stage was 11% higher than the integrated option. The cheap quote won the first conversation and lost the only one that mattered.
What About Halliburton Stock?
Halliburton stock—ticker HAL on the NYSE—is a real thing. Monarch is not a stock. People type 'monarch stock' when they mean 'Halliburton stock' or 'Monarch platform.' They're different.
And here's the uncomfortable truth from the procurement side: stock price should rarely change a service buying decision. I don't use daily stock moves to choose a cementing pump. I do use Halliburton's financial strength from its 10-K to screen for counterparty risk. Halliburton's 2023 10-K lists operations in around 70 countries, which tells me they have scale and logistics reach. It doesn't tell me whether their completion design team in my basin understands my reservoir. That's a technical and operational answer, not an investor answer.
If a salesperson starts talking about stock price, they're not talking about your well.
Change the subject back to stage cost, cycle time, and what happens when the job goes wrong.
How to Tell Which Scenario You're In
- If you have four or more engineers who can independently run completions designs, you're in Scenario 1.
- If you have one or two technical people and zero dedicated project admin, you're in Scenario 2.
- If nobody on your team has completed a well in this basin, you're in Scenario 3.
- If somebody just told you to cut your capital program by 20%, you're in Scenario 4.
Bottom Line
No single Halliburton setup is right for everyone. You need a scenario plan, not a slogan. Look at PSLs as a package, use the agile field development approach to keep decision points close to data, use Monarch if you need a reliable audit trail, and keep stock price in the brokerage account where it belongs.
And if you came here through a typo and you're looking up 'how to get hair' as in the stuff on your head, I can't help. But if you want to keep the hair you have during budget season, use total cost, run short decision loops, and don't let stock talk derail the conversation. That's as close to a haircare routine as I'll ever get.
