This paper reviews previous work done on mathematical modeling of the chemical reactions between sandstone and mud acid, which is a mixture of HF and HCl acids. These models are lumped-parameter model, two-parameter model, four-parameter model, and detailed chemistry models. The models are compared with the experimental data at different flow rates. The lumped-parameter model simplifies the chemistry of the dissolution of sandstone minerals with mud acid. The two-parameter model predicts lab experiments at high flow rates only. Predictions based on the four-parameter model agreed with the experimental data over a wide range of flow rates. Detailed chemistry models have no advantage in predicting experimental data over the four-parameter model. In addition, detailed chemistry models fail to predict coreflood experiments at low acid injection flow rates.
