Fig. 18. Isopach map from
the base of the Ferry Lake Anhydrite to the base of the
Cotton Valley "B" limestone. Contour interval,
50 ft. Fig. 20. Structure map
(1989) on top of the McFearin/Davis "H"
sandstone with McFearin/Davis producing wells circled.
Contour interval, 100 ft.
Fig. 21. Structure map (1989) on top of
the Cotton Valley Vaughn sandstone. Vaughn sandstone
producing wells are circled. Because there are two
separate Vaughn sandstones, two water levels are shown.
See text for explanation. Contour interval, 50 ft.
Fig. 22. Structure map of the Cotton
Valley Bodcaw sandstone with Bodcaw producing wells
circled. The original and current gas-water contacts are
shown. Contour interval, 50 ft.

Fig. 23. Structure map
(1989) on the base of the Cotton Valley "B"
limestone showing "C" sandstone producing wells
(triangles) and "D" sandstone producing wells
(circles). Updip pinch-outs of the upper, middle, and
lower "D" sandstones are also shown. Contour
interval, 100 ft. Fig. 25.

Fig. 26. Structure map (1989) on top of
the middle Hosston with middle Hosston producing wells
circled. Contour interval, 25 ft.
Fig. 27. Structure map (1989) on top of
the upper Hosston with upper Hosston producing wells
circled. Contour interval, 50 ft.
