Since DME is an expensive solvent, the economics of DME-assisted operations should be considered. To date, technical and economic optimization studies based on various objective functions have been published in the literature for both condensate banking treatment and the water-alternating- https://www.w3.org/1998/Math/MathML" display="inline"> CO 2 /DME process. By optimizing condensate banking treatment, design factors such as slug size, solvent mixture, and injection cycle can be determined to achieve maximum recovery or maximum NPV. For the water-alternating- https://www.w3.org/1998/Math/MathML" display="inline"> CO 2 /DME process, economic evaluation was based on various scenarios considering the recyclability of the injected solvent, oil price, and tax credits. Deriving an optimal injection design method for DME-related processes is crucial for improving the economic feasibility of such projects.
