Investigation on Wettability Alteration of Reservoir Rock During Adsorption of Organic Component of Crude Oil, M.Sc. Thesis Sharif University of Technology ; Ghotbi, Siroos (Supervisor) ; Jafari Behbahani, Taraneh (Supervisor) ; Baghalha, Morteza (Supervisor)
Abstract
This study investigates the dynamic adsorption of asphaltene-in-toluene solutions on pack of wet calcite. All experiments were performed on mineral packs in sand-pack with mesh sizes between 100 to 140 (105 to 150 micron) and porosities between 40 to 46 percent. A UV–vis spectrophotometer was used to monitor the outlet concentration of asphaltenes. Experiments were performed for seven ionic strength of sodium chloride (6 to 1500 mM), five ionic strength of sodium sulfate (6 to 2400 mM) and four ionic strength of these salts mixture (12 to 3300 mM). In previous experiments the asphaltene concentration is 500 mg/l. Also two experments were performed with asphaltene concentration of 2000...
