NXT Energy Solutions is a Calgary-based technology company that provides airborne survey services to oil and gas exploration clients using its proprietary SFD (Stress Field Detector) system. NXT flies a jet aircraft over a defined area, and onboard sensors detect subsurface stress and density anomalies that indicate where hydrocarbons may be trapped underground. After the survey, NXT delivers a report ranking areas by exploration potential, helping clients decide where to focus seismic programs and drilling activity. NXT positions the SFD system as a fast, cost-effective pre-screening tool — a single survey can cover thousands of square kilometers, allowing clients to target expensive seismic programs rather than casting a wide net. NXT's clients are primarily oil and gas exploration companies and national oil companies, with recent focus on Africa and Asia. NXT earns revenue on a fee-for-service basis, charging clients for surveys over defined areas. Revenue is highly lumpy and project-driven, with only a handful of contracts executed per year. The business is asset-light — NXT does not invest in exploration wells or take equity stakes in prospects, limiting capital requirements. NXT sells directly in most markets and uses commissioned independent sales representatives internationally, keeping fixed costs low. Beyond survey fees, NXT can negotiate royalties tied to production from areas it recommends, though this has not been a material revenue source. NXT also holds rights to apply SFD to geothermal exploration and, following a December 2025 acquisition, now holds full SFD rights across all applications, including potential mineral exploration.
