Not the Biggest. Just the Best

Decades of oilfield chemistry experience, a patented catalyst that outperforms the industry’s giants, and a commitment to solving the toughest H2S problems without overcomplicating the job.

Who We Are

From the Lab to the Field.

Mike Callaway has spent his 5 decade career in oilfield chemistry, helping operators tackle hydrogen sulfide in some of the harshest environments. Over the years, he saw the same pattern: scavenger systems that were overbuilt, messy to maintain, and quick to fail.

Instead of making small tweaks, Mike started over. In 2002, he began developing what would become H2SZero, a patented dry catalyst that reacts instantly, runs 3-5x longer, and cleans out without the sludge or bricking that slows everyone else down.

Today, Mike still answers the phone himself, working directly with operators and engineers to solve problems others can’t touch.

OUR APPROACH

Solve First, Sell Second.

We’re not a sales team. We’re a problem-solving company.
When you reach out, you’ll talk directly to someone who understands your challenge, not someone reading from a script. We’ll help you size your system, evaluate your options, and give you an honest answer, even if we’re not the right fit.

That’s why we’ve earned long-term relationships with producers and engineers who are tired of being sold snake oil. We may not be the biggest name in the industry, but we’re proud to be the most responsive and the most honest.

Problem-Solving First
We don’t push a one-size-fits-all system. We start with your stream, your challenges, and your goals, then build the right solution for you.
We’re small by design, which means you’ll always work directly with the people who built the product and stand behind it.
