Carbonated produced water injection (CPWI) might be considered an efficient alternative to handle the largest waste stream while enhancing oil recovery and storing carbon dioxide (CO2) underground. This study was attempt get a deeper understanding of process through synergy between spontaneous imbibition isothermal titration calorimetry (ITC) experiments. The results from experiments showed 7% ...

[1] Electric field bursts were passively observed when a nonwetting fluid displaced a wetting fluid in a porous material (drainage) as well as during imbibition experiments. A sandbox experiment was conducted to study these electrical disturbances using a network of very sensitive nonpolarizing electrodes located at the top surface of the tank. Drainage exhibited many more electrical bursts, wi...

We present analytical solutions for capillary-controlled displacement in one dimension by use of fractional-flow theory. We show how to construct solutions with a spreadsheet that can be used for the analysis of experiments as well as matrix-block-scale recovery in field settings. The solutions can be understood as the capillary analog to the classical Buckley-Leverett solution (Buckley and Lev...

This study experimentally investigates the effect of green polymeric nanoparticles on interfacial tension (IFT) and wettability carbonate reservoirs to effectively change enhanced oil recovery (EOR) parameters. experimental compares performance xanthan/magnetite/SiO2 nanocomposites (NC) several materials, i.e., eucalyptus plant (ENC) walnut shell ones (WNC) with performing series spontaneous im...

Abstract Spontaneous imbibition is a key mechanism of oil recovery in naturally fractured reservoirs. Many enhanced techniques, such as modified salinity brine injection, have been suggested to improve spontaneous efficiency. To predict by process, scaling equations developed the literature where almost none them include effect two critical aspects. One aspect different ionic composition inject...
