Abstract:
A method includes determining reservoir rock and fluid characteristics of a reservoir rock and, based on the reservoir rock and fluid characteristics of the reservoir rock, selecting a core. The method also includes selecting a first surfactant and selecting a second surfactant. In addition, the method includes performing a water block mitigation test using the selected core, the first surfactant and the second surfactant and performing a proppant phase trapping mitigation test using the selected core, the first surfactant and the second surfactant.
