North (or Pri) Caspian oil fields such as Kashagan and Tengiz are among the largest finds of the last 25 years, making the basin one of the most important regions of Asia for production and exploration for years to come. Upper Palaeozoic carbonate reservoirs form part of an enormously thick succession, deposited over a basement with disputed age and origin. Permian and Mesozoic clastic strata also form reservoirs within the upper part of the basin stratigraphy, in a succession strongly affected by salt tectonics.
