Evaluation of Domaniс formation unconventional resources in LUKOIL PJSC

UDK: УДК 553.983
Key words: Domanic formation, shale oil, unconventional hydrocarbons resources
Authors: A.V. Gabnasyrov, PhD, N.A. Lyadova, PhD, I.S. Putilov, PhD, S.I. Solovjev (PermNIPIneft Branch of LUKOIL-Engineering LLC in Perm, RF, Perm)
Main purpose of this paper was to evaluate unconventional resources of Domanic shales within Volga-Ural and Timan-Pechora basins. Unconventional resources of Domanic formation are studied very poorly. Well known, shale plays have very complicated geology. Because of that we generalized previous geological reports, revised all existed standard, special and geochemical (including Rock Eval) core studies and well logging. Those studies results were analized. Core-Core and Core-Log plots were made. All the materials mentioned above were used for generation of maps of unconventional exploration features (such as organic matter maturity, lithology variation, total organic carbon content etc.). Parameters of Domanik shales were compared with parameters of unconventional plays of United States and Canada. Geology of Domanic shales was specified. Criteria of ‘sweet spots’ in Domanic formation were determined. Territories for further exploration works were localized. After generalization of all geological materials, such as well logging and core analysis, mentioned data were comparing with some shale projects in USA. Based upon all new information and criteria (new relative to traditional traps) a new program for further exploration of unconventional resources in Domanic shale has been developed.
