Prospect for Natural Bitumen Alternative Production Methods and Comprehensive Application of Bitumen-Bearing Rocks in the Republic of Tatarstan

摘要

At present about 450 deposits of natural bitumen have been identified in Tatarstan. They possess a wide range of geological characteristics of the productive formation occurrence, mineral-petrographical and physical-chemical properties of the natural bitumens, permeability and porosity. Yet, in situ combustion and cyclic steam stimulation have not been proven in the pilot-field operations. To data these technologies are not profitable and are not desirable for natural bitumen deposits developed based on the application criteria.
