Patterns of hydrocarbon trap filling in Nozhovsky salient territory of Perm krai

Subject of the research are local hydrocarbon traps in Nozhovsky Salient territory of Perm Krai. Urgency of the research stems from the need for hydrocarbon reserves replacement and production compensation. The aim of the study is to establish patterns of hydrocarbon trap filling in order to improve the reliability of resource prediction on promising uplifts, as well as to find targets for further exploration of hydrocarbon fields, which are already under development. The results of geological and geophysical data statistical analysis allowed identifying oil and gas occurrence features and level of trap filling. Based on the identified patterns, methodologies of zonal prediction have been developed for factors of hydrocarbon trap filling within the Nozhovsky Salient. Re-appraisal of exploration target resources and prediction of factor of trap filling for the pools having uncertain fluid contact and reserves not listed in the State Register of Reserves were carried out during the course of practical approval of the methodologies developed
