9.-Maps showing thickness <strong>of</strong> <strong>the</strong> s<strong>and</strong>y parts <strong>of</strong> zones 28, 58, 67, <strong>and</strong> 93 in <strong>the</strong><br />
Atoka Formation. Thickness lines are dashed where projected; interval is 20 feet. Numbers<br />
indicate thickness <strong>of</strong> mapped zone, in feet. (See fig. 11 <strong>and</strong> table 3 for well number <strong>and</strong><br />
location.) Stipple indicates possible reservoir area around well reported as producing or<br />
having a show <strong>of</strong> gas, including areas around wells not identified in this report <strong>and</strong> drilled<br />
before 1936; diameter is arbitrarily shown as 1 mile to agree with well spacing.
