Abstract

Summary

In this work the physics of a fluid CO2 – crude oil mixture are explained and correlated to the evaluation of the best performance of a CO2 EOR project. The impact of different factors on the miscibility of the two fluids is described. Based on this knowledge some methods for the determination of the minimum miscibility pressure (MMP) are introduced and their pros and cons are discussed. Additionally, the concept of using miscibility enhancing additives to improve the oil recovery for successful CCUS projects is introduced. At the end a good understanding of the complex CO2 – oil mixture and its influencing parameters is developed. The reasons for good or poor miscibility are understood. An approach to make reservoirs applicable for CO2 EOR which were naturally not is shown by the application of the miscibility enhancing additives in order to improve the economics and to provide a proper justification for CCUS.
