For the first in the 1968 year the oil and gas field of middle Miocene sediments have been discovered by drilling the South Andreev Well and then other Wells in the north portion of the West Kuban depression. The objective of the current study was the analysis and interpretation of all information about dispersed organic matter distribution in the karagan-konka-sarmatian sediments of West Fore-Caucasus. The reviews of variation and peculiarities of distribution of scattered organic matter in the karagan-konka-sarmatian sediments of middle Miocene are very important because these rocks are in the central, most intensively sinking portion of the West Kuban depression that corresponds to maximum temperatures in their sediments or zone of the oil generation. The accumulation of these deposits occurs in different conditions. The big quantity of geochemical date about concentration of organic matter in the litologo-stratigrafical complexs of the the karagan-konka-sarmatian deposits show that the accumulation and distribution of the organic matter had been influenced by the sedimentary transgressive-regressive cycles. The paleontological studies of flora microfossils defined the complexes of fitoplankton - basic source of organic matter of middle Miocene sediments.
