Figure 7.1. Comparison of the Upper Almond facies and production map (a) to the Almond-Madison isochron (b). The drainage divide separating the two northeast-trending channel complexes is thought to be a syndepositional feature related to inherited Paleozoic structural features. The SRU Lineament defines the hinge of the paleostructure and Upper Almond drainage divide. The 5-2 Lineament forms the approximate southern boundary of the northern channel complex. Bubbles of cumulative gas production (normalized for the 1st 180 days) are displayed on the facies map.
