Abstract

Iktissanov V.A. and Zakirov S.N. in their paper “Characteristics of sustained-production stage of long-life oil fields” justify the 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, etc. In this paper, we offer our comments to the paper of these authors and provide some theoretical and practical suggestions regarding consideration of fundamental concepts of subsurface reservoir geology and the most recent proven phenomena of reforming of oil fields and replenishment by oil from the Earth's deep interior while reserves’ estimation and field development planning. Scientific, operational, and logistical problems are discussed, as well as possible ways to deal with the challenges.

Key words:

crystalline basement, reserves estimation, oil replenishment, synthesis, field development planning, oil-bearing channels, geologic models, oil recovery factor, hydrocarbons, geologic prospecting, in-place potential resources.
