Study of the possibility of using geochemical methods for oil production allocation during commingled production from two reservoirs in a field in Western Siberia

Commingled production from several reservoirs significantly complicates the control and regulation of field development, largely due to the need to allocate total oil production among all reservoirs perforated in a well. Currently, there is no widely accepted and satisfactory solution to this issue. The oil and gas industry increasingly employs geochemical methods as one approach to address oil production allocation. This study aims to evaluate the applicability and adaptation of geochemical methods of oil production allocation in the conditions of commingled production from two reservoirs at a field in Western Siberia. The study results confirm the applicability of geochemical methods in this field. The authors conducted oil production allocation for two wells with commingled production. The results align with the geological and physical characteristics of the reservoirs, as well as being supported by inflow profile measurements. The practical significance of this work consists in further dissemination of successful experience of oil production allocation using geochemical methods in the conditions of commingled production.
