Oil Recovery Factor Assessment Results for Sites of the Sredne-Ugutskoye Field

Oil recovery factor (ORF) assessment for sites of the Sredne-Ugutskoye field was performed applying various methods. For this field, the ORF prognostic assessment applying the existing methodological approaches is very relevant, as well as the selection of the most appropriate and accurate ORF calculation methods, taking into account the specific features of the geological structure of formations and reservoirs. The research objective is to obtain an adequate assessment of the ORF for productive sites of the Sredne-Ugutskoye field. With the help of a whole group of methods (analogy, empirical-analytical and empirical-statistical methods), predictive calculations of the ORF value for a number of Jurassic-age development sites were performed.
