To enlarge the resource base of the oil and gas industry of Russia and provide the ESPO pipeline with hydrocarbons, it is necessary to explore new oil and gas potential lands for the purpose of identification of pay zones. On the basis of analyzed evidence from deep drilling and thematic researches, the authors consider structural features of petroleum complexes in the areas of junction of the Anabar and Syugdzher petroleum regions, possibilities of oil-and-gas traps being formed in Vendian and Lower Cambrian carbonate deposits and in areas of Middle Cambrian reef massifs. Areas of probable development of reservoirs and fluid caprocks are forecast. Oil and gas accumulation zones which can be of high priority in carrying out geological studies in the south of the Anabar petroleum region are identified. It is proposed that seismic studies for the purpose of localizing prospects and choosing a prospect drilling site should be performed.

Keywords: Siberian Platform, Anabar and Syugdzher petroleum regions, petroleum complexes, Vendian, Cambrian, facies regions, reef massifs, zones promising for oil-and-gas accumulation.
