Fluid Flow Properties of WAG Injection Processes

D13 FLUID FLOW PROPERTIES OF WAG INJECTION PROCESSES Abstract 1 Immiscible water-alternating-gas (IWAG) experiments performed on equilibrated fluids are summarised together with the corresponding two-phase gas-oil and water-oil displacements. Experimental studies at reservoir condition and also mechanistic experiments over many years have shown accelerated oil production and higher core flood oil recovery as a result of three-phase flow. The three-phase effects that are included and analysed are; trapped gas and mobility for secondary processes (ex. water after gas injection). The oil recovery from the different oil recovery processes represented by; gas water and WAG core displacements are also compared. The
