Abstract
A method for testing solid acid hydrolysis in a formation. The method includes introducing a test sample into a test cell, where the test sample includes an upper structure, a lower structure, and a solid acid disposed between the upper and lower structures. The pressure and temperature of the test cell are increased to simulate downhole conditions. A velocity of an acoustic p-wave and/or acoustic s-wave is through the test sample is measured while the temperature is increasing from an initial temperature to a final temperature. A temperature of onset of solid acid hydrolysis based on the measured velocity is determined.
