... using a 2D visual Hele-Shaw cell, to visualize production mechanisms during the chemical flooding process. The 2D nature of the system allows for an understanding of whether chemicals sweep incremental oil from along the same channels as the pre-formed water or if new displacement channels are formed...

..., these displacement tests showed damage due to asphaltenes between 18% and 27%. The numerical model was developed using Simulink tool, from MATLAB. This model was validated with the experimental results, obtaining a satisfactory agreement, with relative errors between this data less than 5%. Different regimes...

...%. The paper discusses the mechanism responsible for the oil displacement for each injection strategy and presents how the core-flood tests can be used to model gas injection for a sector of the heavy oil reservoirs of Suriname. enhanced recovery Upstream Oil & Gas primary drainage Modeling...

..., include: extended periods of oil production at very high water cuts; and, much higher recovery factors than could be predicted from conventional theory. Mechanisms that have been proposed include: pressure support; unstable displacement and creation of water channels; water imbibition from those channels...
