{{#category_index:F|fault seal analysis}} Efforts to predict whether a fault represents a barrier to the flow of formation fluids because it juxtaposes impermeable rocks against permeable ones. Generally footwall and hanging-wall fault slices (q.v.) are interpreted as to probable permeability and then they are superimposed. Fault seal analysis may also involve predicting a probability that clay will be smeared out sufficiently along a fault surface to prevent the flow of fluids across the fault (clay-smear potential).
