Measurement of Cl : Br Ratios in the Porewater of Clay-Rich Rocks—A Comparison of the Crush-and-Leach and the Paper-Absorption Methods

Figure 5

(a) A pore-scale conceptual model of the different porewater fractions found in a low-permeability clay-rich sedimentary rock. (b) The paper-absorption method extracts porewater from the largest interconnected pores. In this example, partially drained pore spaces are assumed to be connected in the third dimension.
