In north-eastern Bulgaria, within Moesian Platform, one commercial oil and gas field and several smaller semi-commercial gas accumulations, located onshore, have been established. In continuation of this tectonic unit in Western Black Sea Basin there are several more accumulations of hydrocarbons. The object of this research is NE part of Moesian platform in Bulgaria onshore and offshore. The purpose of the present study is clarifying the source rock potential of the sediments by burial history and thermal maturity modelling of the studied area taking into account the influence of all factors for the formation of the potential oil and gas generation sediments. After retrospective analysis of the potential source rocks with Mesozoic and Cenozoic Age, 1D petroleum-system modelling was performed in several tectonic subunits of NE part of Moesian Platform. The 1D models of thermal maturity show that the studied sedimentary sequences are at different stages of thermal maturity of organic matter in them: in the northern part of the study area the sediments with Jurassic and Tertiary Age have not reached the zone of oil generation; in the south-eastern offshore part of the studied area the Tertiary sediments are in immature stage and could generate biogenic gas, but Jurassic sediments have reached the stage of the "oil window".
