Development and Validation of a Sandstone Acidizing Model with a New Permeability Response Model Conference Paper uri icon

abstract

  • A large effort has been devoted over the years to modeling of the sandstone acidizing process. Yet, there has been little laboratory validation of the models that are being used. In fact, most comparisons between theoretical models and experiments are still made with just one set of laboratory results - those of Lindsay conducted with 3 inch Berea cores over twenty-five years ago. In this paper, we implement a rigorous model of the permeability response to a sandstone acidizing simulator. The permeability model includes the effects of changing rock morphology and mineral distribution on permeability prediction. We conduct a series of sandstone acidizing core flood tests, and verify the model by comparing it with new laboratory data. This comparison not only provides a validation of the permeability model, but also of the two-acid, three-mineral model of sandstone acidizing, a commonly used model of the sandstone acidizing process. The applicability of the sandstone acidizing model to field applications is then illustrated by history-matching the actual response during a well treatment with the model.
