Over the past decade, lithological traps associated with turbidite sedimentation have been increasingly identified in petroleum geology. On the Sakhalin Island shelf, in the studies by L.S. Margulis, V.V. Kharahinov, V.I. Shegai, A.L. Volkonskaya and co-authors the probability of the existence of these Miocene traps is substantiated, and their main criteria are presented. This hypothesis is proven by data of deep exploratory wells drilled on the Sakhalin Island shelf. Based on an integration of geological, geophysical, and well data from the north-eastern shelf of Sakhalin Island, the authors discuss the prospects for identifying and mapping non-structural stratigraphic turbidite-type traps in Miocene deposits. A comparative analysis of probable genetic and morphological analogues with Cretaceous-Paleogene stratigraphic turbidite-type traps at the passive Atlantic margin of Gayana and Surinam (north-east of the South American continent) is presented. Stratigraphic traps of this type include linear feeder channels cutting through the basin’s paleoshelf and paleoslope, as well as discharge areas of clastic material in the neighbouring deep-water part of the abyssal slope. A comparative analysis of publicly available data from two regions of the world’s continental shelf (the north-eastern Sakhalin shelf and the shelves of Guyana and Suriname) allowed identifying the typical structural features and depositional environments of non-structural (stratigraphic) hydrocarbon traps. The study substantiates promising hydrocarbon-saturated exploration targets on the north-eastern Sakhalin shelf that are structurally similar to oil and gas fields on the deep-water shelves of Guyana and Suriname.
