Paper Number: SPE-206080-MS
... was evaluated by recording production data from unsteady-state coreflood experiments. The injection of the chemical with equilibrated gas resulted in condensate saturation to decrease from 19.6% to 6.5%. This decrease was not instantaneous and took some time to occur indicating that the chemical needs time...

... For evaluating the developed AI framework we developed a synthetic reservoir box model ( Figure 2 ) in order to retrieve the injection and production data over a time horizon of 4.5 years. The reservoir is inclined, and has four injector wells in the central part of the reservoir and four producer wells...
