Abstract
Developing fields with a large gas cap and a volumetric oil rim requires continuous improvement of oil displacement technologies. This necessity arises from the heterogeneity of reservoir properties and, in some cases, unfavorable phase mobility ratios within the reservoir. Without timely adjustments in reservoir management strategies, there is a considerable risk of reduced sweep efficiency and displacement, which can lead to failure to achieve the design levels of inventory production. In addition to managing oil recovery in gas-supported reservoirs, the effective financial and technological utilization of associated petroleum gas is also critical. Choosing technologies that simultaneously increase oil recovery and ensure the planned use of APG is currently a priority for oil and gas companies.This paper reviews gas and gas-chemical methods for enchancig oil recovery and assesses the potential effectiveness of these methods in the context of the Novoportovsky oil and gas condensate field.
