Abstract
A system and a method for determining a zeta potential of a core plug. The system has a first fluid and a second fluid that is less conductive than and immiscible with the first fluid. A core holder holds the core plug. An upstream reservoir, an upstream trap, and an upstream external electrode cell are fluidly coupled to each other and one end of the core holder. A downstream reservoir, a downstream trap, and a downstream external electrode are fluidly coupled to each other and another end of the core holder. A controller determines the zeta potential of the core plug based on the core plug differential pressure and voltage. Each of the upstream reservoir, the downstream reservoir, the upstream trap, and the downstream trap contain some of the second fluid. The first fluid fills the core holder and separates the second fluid from the core holder.
