The Evolution of a Career: From the Hand to the Palm

There was a time when automation meant you could hear it working. Pneumatic controllers had a rhythm to them. Clicks, hisses, the steady pulse of air moving through valves and diaphragms. You walked up to a piece of equipment and it told you how it was doing before you ever looked at a gauge. You could feel it.

When Eric Fidler sat down with us on Wisdom at the Wellhead, one of the things that stuck with me was how naturally he moved through that history. He started his career wiring gas turbines for Baker in 1979. Back then, the controls were a mix of pneumatics, hydraulics, and whatever early electronics were available. The computing power that ran an entire university lab filled a building. Eric helped step data through three separate computers just to get it into Georgia Tech's mainframe.

Kevin made the point during our conversation that what used to fill a room now fits in the palm of your hand. And that's true. But I think the more important point is what hasn't changed. The objective is still the same. We're still trying to produce energy safely, efficiently, and with the best information available. The tools got smaller. The mission didn't.

What the Old Tools Taught Us

Here's what I've seen over the years. The people who came up through the pneumatic era understand something that's hard to teach from a screen. They understand the physical reality of what's happening inside the equipment. When a controller failed in those days, you couldn't restart a program. You had to understand the spring tension, the air supply, the mechanical relationship between the input signal and the valve position. You had to know the asset.

Eric talked about being given opportunities early in his career to tune processes that weren't working. Things other people were struggling with. And because he was curious, because he didn't just wire what was on the drawing but actually took things apart to understand how they worked, he built a deep knowledge of how production processes interact with one another. That foundation carried him through a career that spans over a hundred countries.

That kind of knowledge doesn't come from a dashboard. It comes from years of putting your hands on the equipment and learning what it sounds like when it's right and what it sounds like when it's not.

What the New Tools Make Possible

Now look at what sits at the wellhead today. An edge controller that combines real-time compute power with traditional programmable control. It can run analytics on live production data, detect problems as they develop, and let an operator respond in the moment instead of after the fact. Eric showed us one during the episode. It's compact, it's powerful, and it can do in seconds what used to take a full day of walking lines and reading gauges by hand.

Kevin pointed out that automation used to mean big panels and a lot of equipment. Now it gets smaller and more capable every year. That's not just a technology story. It's an access story. The kind of computing power that used to belong only to the supermajors is now within reach for mid-market operators who are watching their budgets carefully and need every dollar to prove its worth.

That's the part that matters most to me. Not that the hardware is impressive, but that it puts real capability in the hands of the people who need it most and can least afford to waste time and money on tools that don't deliver.

The Bridge Between Generations

One thing I know. If you're running a team right now, you've probably got people on both sides of this evolution. You've got experienced hands who grew up tuning equipment by feel. And you've got younger engineers who are comfortable with screens and data but may never have traced a pressure problem through a physical system with their own hands.

Both of those skill sets are valuable. Neither one is complete on its own. The veteran who dismisses the edge controller because "we've always done it this way" is leaving performance on the table. But the younger engineer who trusts the screen without understanding the physics behind it is building on sand.

Eric made this point when he talked about AI and automation in the field. The technology is only as good as the knowledge behind it. Without understanding what you're automating, the data is just noise. And noise doesn't make you money. It costs you money, because it gives you false confidence in decisions that aren't grounded in how the asset actually behaves.

Eric Fidler's Advice for Leaders Managing This Transition

Eric has lived this evolution from beginning to end. He wired turbines, tuned pneumatic controllers, led global automation teams, and now works at the edge of what's possible with Sensia. Here's what he'd pass along to anyone managing a team through this shift.

Don't let your people skip the fundamentals. Before anyone automates a process, they need to understand how it works mechanically. If they can't explain what the valve does without the computer, they're not ready to put a computer on it.

Use the new tools to extend field knowledge, not replace it. Edge computing and real-time analytics should be confirming what experienced operators already suspect and catching what they can't physically be present to observe. The technology serves the expertise. Not the other way around.

Close the gap between your veterans and your digital team. Put them together on projects. Let the veteran explain why the equipment behaves the way it does. Let the younger engineer show what the data reveals that you can't see with your eyes. That exchange is where the real value lives.

Remember that the objective hasn't changed. The tools went from pneumatics to edge controllers. The panels went from filling a wall to fitting in your hand. But the job is still the same: produce energy safely, efficiently, and with the best information you can get. Don't let the technology distract you from the mission.

Final Thought

I sat across from Eric during that conversation and thought about how much ground his career covers. From wiring gas turbines as a college kid in 1979 to advising global operators on edge-to-enterprise automation today. The tools changed completely. The curiosity that made him good at this work never did.

That's the real lesson in the evolution from the hand to the palm. The technology will always keep moving. The question is whether the people using it still understand what they're managing. Because the smartest controller in the world is worthless if the person reading the screen doesn't know what the well is trying to tell them.

Respect the history. Use the tools. But never stop understanding the asset. That's what separates an operator from someone who just watches numbers move.

If this hit home, you'll want to hear the full conversation.
