NXT Energy Solutions

Stress Field Detection (SFD®) is a geophysical survey technology developed by NXT Energy Solutions Inc., headquartered in Calgary, Canada. SFD® uses a reservoir-scale gravitational detection method to rapidly identify and rank prospect-level leads in order to focus exploration efforts. SFD® is becoming recognized as the only airborne geophysical tool which provides information on areas conducive to fluid entrapment in sedimentary basins. The SFD® method has proven highly effective at identifying potential hydrocarbon traps in a wide variety of geological settings onshore and offshore, including thrust-fold belts, foreland basins, sub/pre-salt plays, and extensional regimes. SFD® surveys have been executed worldwide, including Canada, U.S.A., Mexico, Colombia, Argentina, Guatemala, Belize, Pakistan and Syria. Integrated G&G case studies and technical publications are available attesting to the efficacy of the SFD® technology. In 2013, NXT published two joint papers with the NOCs of Mexico and Pakistan, which can be found at www.nxtenergy.com. In petroleum exploration, the five major criteria assessed are source, migration, trap, reservoir, and seal. SFD® responds to the anomalous density and stress conditions produced by the combined presence of trap, reservoir and seal. In effect, SFD® provides an independent assessment of trapped fluid potential for prospect de-risking.
