The rationale behind the selection of objects for physical modeling based on geological and statistical data

   The intricate structure of the oil rim of oil and gas deposits is a determining factor in the peculiarities of its development. The exploitation of productive formations results in the depletion of oil reserves due to the uncontrolled withdrawal of gas. The application of an unbalanced oil withdrawal and waterflooding process results in a reduction in the oil recovery factor. The article considers the issue of enhancing the efficiency of oil rims exploitation technology, with a particular focus on the research conducted into the displacement process of oil by gas agents. The authors of the article present the applicability criteria of enhanced oil recovery technologies, which serve as a basis for selecting the method of stimulation of the reservoir based on its geological and physical characteristics. Additionally, the results of the technology efficiency assessment for each reservoir are presented, along with a justification for the application of enhanced oil recovery methods. Finally, the article justifies the choice of research objects based on the application of enhanced oil recovery methods for different fields. The results of the ranking led to the identification of the criteria that justified the sites for water-gas impact testing. The following sites were identified as suitable for water-gas impact testing: BU11 2 (Urengoy oil and gas condensate field), BT11 0, BT11 (Zapolyarnoye oil and gas condensate field), BU8-9 3 (Yen-Yakhinskoye oil and gas condensate field), BU9 2 (Pestsovoye oil and gas condensate field), PK1 (Tazovskoye oil and gas condensate field), ACh3 0, ACh3, ACh4, ACh5 (Yamburg oil and gas condensate field).
