This document summarizes an NMR technique for identifying hydrocarbon deposits from the surface to depths of 5 km without drilling or interpretation. It detects the presence of hydrocarbons directly by transmitting signals tuned to their resonance frequencies and detecting the re-radiated signals. Surveys can map deposits over tens of thousands of square km and determine depth, thickness, and pressure of horizons with over 90% accuracy. The technique exceeds seismic in precision and can reduce exploration costs.
