$this->bbcode_second_pass_quote('SoothSayer', 'A') few years back the Caspian Sea was going to be "the future Saudia Arabia".
.
It won't. it has sizeable reserves however. it was not much explored by the soviets because it was easier for them to increase production in western siberia.
Kashagan in the Kazzakh sector has about 13 Gb (billion barrels) of reserves, it's one of the largest untapped fields in the world. According to ASPO, whose estimates are pessimistic, Kazakhstan has 50 Gb of original reserves, and only 6 have been used so far. Probably, of all country with dozens of Gb's of reserves, Kazakhstan is the less depleted one.
Azerbaijan is severly depleted as faras onshore areas are concerned, but offshsore production is only starting. Production jumped in recent years and the country will soon export ~1 Mb/d.
The russian side have not been much explored, but a few good finds have been made, including on oshore gas giants. (astrahan) discovered long ago but not exploited.
Turkmenistan have some sizeable fields, exploited for long. Iranian sector is unexplored, nodoby knows whether there is a big potentiel.
Overall, there may be 100 Gb to be produced there.
BUT :
It's very low grade oil, with extremely high sulfur ratio. Tengiz crude in Kazakhstan can only be exported after sulfur have been removed.
Also the fields are very deep (often >3000 meters, while persian fulg fields are less than 1500 m deep), what means high pressure, high temperature.
The climatic conditions are extreme. The area is landlocked, making export difficult and costly.
There are political problems too.
All this explains that exploration is progressing quite slowly, and that many projects are well behind shedule. kashagan is several years late, it should already be onstream.
