M91FG108.JPG|{{figure number|5}}The barrier bar-shoreface interval of the Brent Group reservoir in the Thistle field, UK North Sea, shows an upward-increasing permeability profile. This pattern is favorable to a high sweep efficiency (from Williams and Milne, 1991). Reprinted with permission from the Geological Society.
