Permian petroleum system of Lena-Anabar trough - lithological-geochemical studies (at an example of well Ust’-olenek 2370)

Abstract

Lithofacies of different genesis were determined within the Permian sequence, basing on analysis of core descriptions. The best reservoirs are associated with deltaic sand bodies. Permian source rocks with marine organic matter were distinguished. Initial organic matter parameters were estimated, initial good-excellent petroleum potential was suggested. Lithological-geochemical study results for core samples from one of the northern wells of Laptev Sea coast are published for the first time.
