Sweet-Spot Zonation-Guided Cyclic Gas Injection for Offshore Buried-Hill Condensate Reservoirs: Integrating Enhanced Recovery with CO2 Storage
Fractured buried-hill condensate reservoirs are often developed under near-dew-point conditions, where retrograde condensation and preferential fracture channeling jointly reduce sweep efficiency and impair deliverability. This study proposes a sweet-spot-guided differentiated cyclic injection workflow that couples m...
