Abstract
In addition to surface geologic and geophysical investigations, Panchromatic SPOT and Landsat Thematic Mapper (TM) data were merged using an IHS approach to produce a satellite composite image to use as a basis for structural geologic analysis of the oil- and gas-bearing regions of Azerbaijan, including the South Caspian and Kura Basins. With the development of new exploration technology, various nonseismic reconnaissance methods, such as remote sensing, gravity, and magnetics for oil exploration have been substantiated and improved. The Azerbaijan and surrounding mountain ranges are favorable for studying natural hydrocarbon seepages. Most of the seepage occurs in faulted and mud volcano areas onshore of the Caspian Sea in Azerbaijan. Determining the geometry of the fault system from analysis of remote-sensing data allows prediction of (1) vertical oil migration from source rocks into tectonic traps in overlying formations and (2) quantitative volume of oil reservoirs.
