Prospects for identifying local petroleum targets in the junction zone of the Laptev Sea shelf and the deep-water Eurasian Basin
Abstract
Junction zone of the shelf structures of the Laptev Sea with the deep-water Eurasian Basin in the Cenozoic sedimentary cover exhibits the areas of development of clinoform complexes and alluvial fans of terrigenous material. Here, a high probability of hydrocarbon accumulation is predicted due to ongoing avalanche sedimentation.
As a result of 2D/3D basin modelling based on seismic data from the Taimyr zone of the Laptev Sea shelf, the most probable models of generation, migration, and accumulation of hydrocarbons were obtained and zones of hydrocarbon saturation (70–90%) were identified in the Middle-Upper Paleogene complex.
