Abstract

WETTABILITY PLAYS AN IMPORTANT ROLE IN OIL RECOVERY PROCESSES AND RESERVOIR PRODUCTIVITY. WETTABILITY ALTERATION CAN OCCUR AT DIFFERENT STAGES DURING THE PRODUCING LIFE OF A RESERVOIR. OIL RECOVERY FROM OIL-WET RESERVOIRS CAN SIGNIFICANTLY BE INCREASED BY ALTERING ITS WETTABILITY FROM AN OIL-WET TO A WATER-WET CONDITION. CHEMICAL AGENTS LIKE SURFACTANTS ARE KNOWN AS WETTABILITY MODIFIERS IN OIL-WET SYSTEMS. MORE RECENTLY, NANOFLUIDS HAVE BEEN CONSIDERED AS POTENTIAL WETTABILITY MODIFIERS. IN THIS WORK, THE EFFECTIVENESS OF TITANIUM OXIDE NANOFLUIDS WITH LOW CONCENTRATION IN ALTERING THE WETTABILITY OF SANDSTONE CORES WAS EXPERIMENTALLY STUDIED. USING TIO2 ANATASE NANOPARTICLES IMPROVE RECOVERY FACTOR SIGNIFICANTLY. SEM RESULTS SHOWED HOMOGENOUS DEPOSITION OF NANOPARTICLES ONTO CORE PLUG SURFACE. EDS CONFIRMS DIFFUSION OF NANOPARTICLES IN POROUS MEDIA AND UNIFORM DISTRIBUTION. THE EFFECT OF NANOFLUIDS ON WETTABILITY ALTERATION WAS INVESTIGATED BY CONTACT ANGLE MEASUREMENTS ON THE ROCK SURFACE BEFORE AND AFTER TREATMENT WITH THE NANOPARTICLE SOLUTION. CONTACT ANGLE MEASUREMENTS SHOWED THAT THE ROCK WETTABILITY CHANGED FROM OIL-WET TO WATER-WET CONDITION AFTER TREATMENT WITH NANOPARTICLES.
