The authors present the results the results of geochemical studies of Organic Matter in Jurassic-Cretaceous sedimantary rocks within the Arkticheskoe and Neitinskoe oil and gas condensate fields situated on the Yamal Peninsula. It is shown that low organic matter content (average Total Organic Carbon content of 1.26 % per rock) of predominantly terrestrial (continental) origin and low present-day generation potential is typical of all studied Lower Cretaceous (Tanopcha, Akh) and Middle Jurassic (Malyshev, Leontyev) formations. According to molecular bituminological data, the fossilization of Organic Matter in the studied rocks occurred under mildly reducing conditions in a basin with terreginous sedimentation and normal water salinity. At the same time, the Middle Jurassic section contains some intervals with relatively elevated concentrations of terrestrial Organic Matter (TOC content reaches 2.22 % per rock) at a high catagenesis level (at the MK32 stage), which have partially realized their hydrocarbon generation potential. The values of molecular geochemical parameters indicate a predominantly aquatic (marine) genesis of Organic Matter found in a sample from the lower part of the Akh Fm (Arkticheskaya‑16 well, K1b, 3015 m). However, given the limited distribution of these rocks, their low Total Organic Carbon content (0.87 %) and low Hydrogen Index values (13 mg HC/g TOC), the Akh Fm cannot be regarded as a significant oil source interval in the study area.
