Seal thickness is not an independent variable. Thin seals have a higher probability of being laterally discontinuous, of being fractured completely, or of having local variations in fracture intensity or pore throat diameter that provide a leakage pathway. Similarly, thick seals have a higher probability of being laterally continuous, having fractures terminate within the seal, and having at least one shale lamina with a high displacement pressure.
