Comprehensive interpretation of geochemical, physicochemical studies and PVT parameters for verification of phase zonation of reservoirs (a case study of the Eastern Urikhtau field)

Background: Correct identification of the fluid phase state (oil or gas condensate) at the Eastern Urikhtau field is critically important for reliable reserve estimation and the selection of an appropriate development strategy. Anomalously highgas-oil ratio values in wells EU-6 and EU-7 (up to 1000 m³/m³) as well asdiscrepancies between the hypsometric levels of the presumed gas-oil contact and…
