A Novel CO2 Flooding Based EOR for Sandstone Reservoirs
MetadataShow full item record
In an attempt to contribute to the development of CO2-EOR, this project proposes a novel Chemical-Alternating-Foam (CAF) flooding which couples chemical (surfactant and polymer) flooding with the conventional CO2 foam flooding. A new foaming formulation is first developed, and then through systematic and thorough investigations, it is discovered that CAF flooding that applied the developed foaming formulation could be a viable and promising CO2-EOR method for sandstones reservoirs.

Evaluation and Optimization Study on a Hybrid EOR Technique Named as Chemical-Alternating-Foam FloodsXu, X.; Saeedi, Ali (2017)A novel EOR method called Chemical-Alternating-Foam (CAF) floods was developed to overcome the drawbacks of the conventional foam flooding, e.g., insufficient amount of in-situ foams and severe foam collapse and surfactant ...
An experimental study of combined foam/surfactant polymer (SP) flooding for carbone dioxide-enhanced oil recovery (CO2-EOR)Xu, X.; Saeedi, Ali; Liu, K. (2015)To better address the issue of viscous fingering and gravity segregation confronted in CO2 flooding, a novel EOR method which coupled the SP flooding with the CO2 foam flooding was presented. Its displacement performance ...
Xu, X.; Saeedi, Ali; Rezaee, M. Reza; Liu, K. (2015)CO2 foam flooding has been widely researched due to its outstanding capacity to mitigate viscous fingering, gravity override and unfavourable injectivity profile, which enables CO2 flooding to be more applicable and ...
