NXT Energy Solutions Inc. provides aerial survey service to the oil and natural gas exploration and production industry. The Company's Stress Field Detection (SFD) survey technology is an airborne survey system that is used in the oil and natural gas exploration industry to help in identifying areas with hydrocarbon reservoir potential. The Stress Field Detection (SFD) survey technology is based on detecting subtle changes in earth's gravitational field from an airborne platform. SFD data acquired is analyzed and can be used to find variations in sub-surface geological stress patterns, which are indicators of potential reservoir and trap formations. The Company's aerial SFD surveys provide a method for clients to focus their decisions related to land commitments and the acquisition of seismic data that is used to locate and delineate exploration prospects. SFD is the airborne tool that provides information on areas conducive to fluid entrapment in the sedimentary column.
