pdf Model of geological structure and petroleum perspective of Neocomian strata belonging to Gydan area (Underpim regional clinoform)
The performed analysis of geological and geophysical data made it possible to refine the regional model of the geological structure of the Berriasian-Lower Aptian strata of the Gydan petroleum bearing area. According to the refined model, the Underpim regional clinoform is fully represented in the central part of the oil and gas area. It is concluded that there are no anticlinal structures capable of accumulating hydrocarbon resources in the Underpim structural-stratigraphic section of the study area, and here the prospects for oil and gas potential of the Neocomian can only be associated with complicated lithological traps. As a result of structural constructions using seismic facies and dynamic features of wave fields, five reservoirs with a zonal distribution were identified in the Underpim clinoform. For each reservoir, the lines of transition of the accumulative slope to the shelf and deep water areas are determined. The analysis of the distribution map of the amplitude characteristics of the seismic record in combination with the structural-geomorphological model of the structure of the Underpim regional clinoform made it possible to identify the most promising reservoirs in terms of oil and gas potential and to identify areas in their composition within which the development of localized sand bodies - traps can be expected.

Keywords: Berriasian-Lower Aptian strata, Underpim regional clinoform, model of the geological structure, promising lithological traps, Gydan petroleum bearing area.
