Remote sensing can be divided into direct and indirect-detecting types at viewpoint of oil-gas resources exploration. Infrared remote sensing technique

which is of direct-detecting type

is based on the theory of microseepage of hydrocarbon reservior. This approach takes advantage of two-peak absorption on 2.27-2.46 μm spectrum related to hydrocarbon elements anomalies of soil. We have established a series of procedures dealing with airborne remote sensing images and anomalous information extraction methods. The accuracy we derived from the contrast with the known oil-gas fields

is 70 percent

and some remote sensing anomalies in the unknown oil-gas fields have been confirmed by succeeded drillings.
