About Us

---

Oasis Emission Consultants, Inc. was founded in 1999 by Christopher Knott and Gregory Hunter with the vision of delivering an automated, real-time testing system designed to meet the stringent standards of EPA Reference Method testing—specifically for natural gas-fired engines. From the beginning, our mission has been to offer clients a dependable and cost-effective service that goes beyond testing. We also provide strategic guidance on achieving compliance through tailored control equipment solutions and operational best practices.

Today, we remain committed to serving our clients in North Dakota, Montana, Wyoming, Utah, Colorado, New Mexico, Texas and Western Canada with innovation, flexible scheduling, reliable service, and deep industry expertise.
