This paper presents examples of xanthan core floods visualized by X-ray tomography. Water and aqueous xanthan solutions are distinguished from each other by addition of sodium iodide (NaI) at different concentrations. One reservoir sandstone and one outcrop (Rosbrae) sandstone core samples were used. The reservoir sample was naturally divided into two longitudinal zones differing in permeability by about 20-fold. The Rosbrae sample was homogeneous, with a permeability of 450 md. Miscible xanthan/water displacement tests were performed on both plugs. Immiscible displacement of light refined oil by xanthan was performed on the homogeneous sample.
