Auger electron spectroscopy (AES) has been used to determine the surface composition of Berea sandstone. Changes in surface composition due to cation exchange and surfactant adsorption have also been observed. The application of AES to nonconducting materials such as sandstones requires special sample preparation and operating conditions to eliminate destructive charging effects. Surface compositions obtained by AES were compared to bulk analyses as well as to X-ray photoelectron spectroscopic (XPS) analysis. Surface compositions of aluminum, iron, sodium and potassium were significantly higher than bulk compositions. After contact with distilled water, AES analysis showed the loss of potassium and sodium from the surface. AES analysis of Berea contacted with MgCl and CaCl solutions showed increased adsorption of chlorine over that contacted with NaCl and KCl solutions. Trends in the adsorption of the surfactants Texas number2 and Triton X-100 were observed by AES.
