Analyses of Natural Gases, 1973.
NTIS: PB 238 125 :96 pages
This publication contains routine analyses and related source data for 278 natural gas samples from 14 states. All of the samples were collected during calendar year 1973 as part of a continuous survey of the free world for occurrences of helium in natural gas. This survey has been conducted in the United States by the Bureau of Mines since 1917. In late 1965, the survey was expanded to include foreign gasfields. The analyses were made by mass spectrometer and a special helium analysis apparatus.
