Ostroukhov, S. B., V. A. Bochrarev, V. I. Petrenko, LUKOIL-VolgogradNIPImorneft, Volgograd, Russia

The article focuses on phase-genetic connection of the fluids of the Central Caspian shelf established on the basis of geochemical coefficients K1a, K2a. These coefficients are derived from the law of alkane thermodynamic distribution between gas and liquid phases.
