Analyses of Natural Gases, 1975.
NTIS: PB 259 351 :82 pages
This publication contains analyses and related data for 234 natural gas samples from wells and pipelines in 21 states and 1 foreign country. All of the samples were obtained and analyzed during calendar year 1975 as a part of Bureau of Mines investigations of the occurrences of helium in natural gases of countries with free market economies. 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. The results of the investigation of the occurrences of helium are published annually to make the information available as soon as possible to the gas industry and the public in general. Seventeen previous publications have presented the results of 10,831 gas analyses prior to 1975.
