It has been for years in applying hydrocarbon’s micro-seepage to prospecting for oil and gas. There are a lot of indirect evidence which are pertinent to hydrocarbon’s microrseepage including anomalies of geomorphology

geochemistry and mineral

and recently known abno-mals of soil chemistry

and vegetation physiology. As a matter of fact

these alteration haloes can be divided into following classes: redbeds bleaching haloes

clay enrichment haloes

car-bonatite enrichment haloes

radiation haloes

heat anomaly haloes

geobotanical anomaly haloes

magnetic anomaly haloes

and haze haloes.All of these haloes might exist in overlain beds of reservior in different scales and types. These phenomena can be used as direct and/or indirect indexes to detect oil and gas information with remote sensing means.According to spectral survey on these alteration haloes

it is shown that every one has its own spectral features obviously in the visible

near-IR

and thermal-IR wavebands. So it is available to look for oil and igas with remote sensing means directly. Finaly

our aim is to select the best wavebands for oil and gas.
