Abstract

The paper reviews the history of studies of the crystalline basement in Tatarstan, and the progress of the ultra-deep drilling program. The paper offers scientific rationale of produced oil and gas fields’ replenishment at the cost of hydrocarbons’ deep inflow through oil-bearing channels connecting the deepseated hydrocarbon source with the deposits in the sedimentary mantle. From a standpoint of the search for hydrocarbon reserves, the crystalline basement is a promising target, however its role as a transiter for replenishment of deposits in the sedimentary mantle with hydrocarbons in the process of continued degassing of the Earth is far more important and justified. A principally new approach to building of geologic and geologic-dynamic models with consideration of fundamental geological concepts concerning forming and re-forming of oil and gas fields and deep degassing processes is offered. Prospects of development of “old” fields that have been produced for a long time, methods of oil recovery factor estimation considering oil migration into a deposit from the entrails of the Earth, necessity to modify methods of reserves auditing and in-place reserves’ estimation, change of material balance equations are justified; theoretical and practical suggestions regarding consideration of fundamental concepts of subsurface reservoir geology are provided. Waterflooding methods have not yet exhausted their potential, on the contrary, in the light of the discovered processes of replenishment of deposits with hydrocarbons and reforming of oil and gas fields at the late stage of development their importance will only increase.

Key words:

forming and re-forming of oil and gas fields, degassing of Earth, crystalline basement, oil-bearing channels, North-Tatarian and South-Tatarian Arches, abnormal and normal wells, carbon, hydrogen, hydrocarbons, oil replenishment, replacement of hydrocarbons, geologic and geologic-dynamic models, water-flooded development, innovative development projects, unconventional hydrocarbons.
