NXT Energy Solutions Inc. is a Canada-based technology company. The Company offers a geophysical service to the upstream oil and gas industry using its gravity-based Stress Field Detection (SFD) remote-sensing survey system. Its proprietary airborne SFD survey can be used both onshore and offshore to remotely identify areas conducive to fluid entrapment to recommend areas with commercial hydrocarbon and/or geothermal potential. The SFD survey system enables its clients to focus their exploration decisions concerning land commitments, data acquisition expenditures, and prospect prioritization on areas with the potential. SFD is an airborne tool that provides information on areas conducive to fluid entrapment in the sedimentary column. The SFD survey is complementary to existing geophysical methods, particularly seismic programs. In pre-seismic applications, SFD can generate high-potential prospect leads in large underexplored areas.
