The Intake Decides the Exhaust

One of the first completions I ever watched go in was a disaster. Not a blowout, not anything dramatic. Just a rushed job on a zone isolation that needed another eight hours of attention and did not get it. Everybody moved on to the next well. Everybody was proud of how fast we cycled through the pad. And for the next twelve years, that well produced at a fraction of what it should have, because water was getting in from a zone we had failed to seal off properly at the start.

Nobody remembered, twelve years later, whose decision it had been to move on. The driller was at another operator. The company man had retired. Somebody new was running production and trying to figure out why this well was such a headache compared to its offset. And the answer, when you finally went back and looked at it, was that somebody had rushed the intake. Back when it mattered. Back when it was still a decision you could make.

I thought about that well when I was listening to Alex Economides explain oxy-combustion to Kevin and Philip.

What Alex Is Actually Doing

Alex described the technology about as plainly as I have ever heard anyone describe a piece of chemistry. An engine has an intake. It pulls in air and fuel. It burns them. It sends the exhaust out the back. That is the whole picture. Normal air is mostly nitrogen with a little oxygen, plus whatever else happens to be in it. When you burn that in a diesel or natural gas engine, you get carbon dioxide mixed up with nitrogen, water vapor, sulfur compounds, and a bunch of other things you did not want. The CO2 concentration is below ten percent. To capture that CO2, you now have to scrub it out of a messy, diluted stream. That is expensive and it is slow and it costs you your margin.

Alex's company does one thing differently, and it is the one thing that matters. They control the intake. Instead of letting normal atmospheric air into the engine, they feed it pure oxygen and fuel. That is the whole trick. What comes out the back is carbon dioxide and water. Just those two things. Water is easy to separate. CO2 that is already close to pure is easy to sell. His words: they can make close to food-grade CO2 off a dirty diesel or natural gas engine, because they decided what got to go into it.

He said the technology sounds simple, and that it is exactly as simple as it sounds.

What Every Engineer Already Knows

Every engineer I have ever worked with has an instinct for this, even if they have never said it out loud. You cannot fix at the output what you failed to control at the input. You can try. You can build a bigger scrubber. You can put in a second stage of filtration. You can throw people and capital at the problem for the life of the project. But the cost of cleaning up a dirty stream is always higher than the cost of not dirtying it in the first place, and it never stops costing you.

Alex is not inventing that principle. He is applying it to carbon capture, where the rest of the industry has been doing the opposite for twenty years. Direct air capture pulls CO2 out of open atmosphere, which is about as dilute as a stream gets. The best DAC companies are running around a hundred and fifty dollars a ton. Alex is running around forty. Same goal, same credit, wildly different cost structure, because one of them is working against physics and one of them is working with it.

See, the other guy is still trying to clean it up. You already decided not to dirty it. There is a long list of businesses in this industry where that is the whole difference.

The Intake Decisions at Total Stream

Bob Baldwin and I built the first version of Total Stream out of a garage, during a period when I was in and out of a hospital bed three times a week on dialysis. We did not have the luxury of rebuilding anything. Every decision we made in those early months had to be right the first time because we did not have the capital or the time to do it twice.

Some of those decisions we got right. We decided early that the structure underneath the data had to be true. Not pretty, not impressive, not beautiful. True. I told our engineers for years that you can be creative with the data you use to find better solutions, but you cannot be creative with the structure in which that data hits. That is everything for getting the data the way you need it. That decision, made at the intake of the company, is still paying for itself thirty years later.

Some of those decisions we got wrong. I am not going to air the specifics, but I will tell you that the ones we got wrong, we are still living with. Not because we cannot fix them, but because the cost of going back and pulling them out is now higher than the cost of working around them. That is what it means to get the intake wrong. It does not kill you. It just quietly taxes you forever.

I have been guilty, more than once, of watching a problem on the output side of something we built and thinking the answer was a better filter. The answer almost always was to go back and look at what we had let in, and decide we were not going to let it in that way anymore. That is harder than building a filter. It is also cheaper, and it actually works.

The Discipline Is Being Obsessive About the Front End

Alex said one thing in that conversation that I want every founder in this industry to sit with. He pointed out that the technology Occam's is using has been around since World War II. It is not new. What has changed is the market, and what has changed is the discipline of the people using it. The companies that are going to win in carbon capture are not the ones with the fanciest technology. They are the ones who figured out that controlling the intake is worth being obsessive about.

That principle lives everywhere in this business. The driller who takes the extra eight hours on the zone isolation is going to outproduce the one who moves on, for the life of the well. The software company that gets the data structure right in year one is going to outscale the one that built a dozen workarounds for a bad schema. The operator who is picky about which joint venture partners he brings into the company is going to spend less time in lawyers' offices than the one who took every check that showed up.

It is not glamorous work. Nobody throws a parade when the thing you did not let happen did not happen. But the operators I have respected the most over forty years all shared the same trait. They were careful about what they let in. They were patient at the front of the process. And they spent the rest of their careers enjoying the margin that careful intake paid them.

Final Thought

My dad was a carpenter. He built houses on that farm in Montana in between crops, and one of the things he said more than almost anything else was that you cannot fix a foundation once it is poured. You can hang the door differently. You can repaint the walls. You can move the furniture around for the rest of your life. But the foundation is the foundation, and what you got right when you poured it is what you get to live with.

Alex is doing at Occam's what the best operators have always done at the wellhead. He decided at the intake that the output was going to be clean, and he stopped trying to scrub his way to a margin that physics was not going to give him. That is not a technology insight. That is an engineering discipline that reaches all the way back to the first person who ever tried to build something that was going to last.

Control the intake. Everything else gets easier from there.

Alex Economides is a fractional CFO at Occam's Technology and an energy transition advisor to New Tech Global. He holds two US patents on carbon market design. On Wisdom at the Wellhead, Kevin Fischer and Philip Richard sit down with him to walk through the chemistry and economics of oxy-combustion, why controlling the intake changes everything that comes out of an engine, and how Occam's is running close to forty dollars a ton when the rest of the industry is stuck at a hundred and fifty.
