Wellbore and Reservoir Thermodynamic Appraisal in Acid Gas Injection for EOR Operations

This study provides insights into the experience gained from investigating thermodynamic behavior of well and reservoir fluids during acid gas injection (AGI) in a hydrocarbon field to enhance oil recovery (EOR) reduce greenhouse emissions. Unlike conventional water natural injection, AGI involves complicated phase changes physical property variations at various pressure-temperature (P-T) conditions compositions, both constitute crucial parts EOR chain. A workflow is developed deal with fluid thermodynamics, which key requirement for successful design operation. The focuses firstly on development models (EoS) simulate injected their integration dynamic models. Subsequently, proposes simulation fluids’ interaction determine Minimum Miscibility Pressure (MMP), yielding evolution miscibility that may appear within reservoir. Flow assurance transportation lines wellbore also considered by estimating hydrate formation conditions.
