NTIS: PB 225 977 :104 pages
This publication contains routine analyses and related source data for 299 natural gas samples from 22 states and three foreign countries. All of the samples were collected during calendar year 1972 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 published herein were made by mass spectrometer and a special helium analysis apparatus, which are described in Bureau of Mines Bulletins 486 and 576.
