Gas‐mixing ratios of samples from 1,038 naturalgas wells of the Hugoton/Panhandle fields of West Texas and Kansas are examined, and well‐defined regional systematics are noted. The helium‐nitrogen ratio of all the Texas fields has a nearly constant value (0.077) and a very sharply‐defined upper boundary. In the Kansas fields, a diflerent value is found for that ratio (0.021), but it is also well‐defined over a large region. Theproportion of methane, the principal gas in all the wells, shows a regional dependence within each of the areas. The observed distribution places constraints on the origin of the threegases, and suggests that they all derive from sources deeper than the sedimentary layer .
