ABSTRACT
The South Caspian Basin comprises a unique set of geologic parameters that rank
it among the most prolific hydrocarbon regions of the world. Surrounded by compressional
orogens, the basin has accu-mulated up to 25 km of sediment, with more than 10
km of this fill deposited in the last 6 m.y. This recent, rapid burial has resulted
in such low temperature gradients that hydrocarbons are still being actively generated
at depths between 8 and 12+ km. The anticlinal structures in the basin are large,
and interpreted to be buckle folds overlying a regional detachment based on the
analysis of regional 2-D seismic data. The combination of a prolific hydrocarbon
system, large undrilled structures, and a favorable political climate for foreign
investment has focused consider-able industry attention on the potential of this
basin.
