Analyses of Natural Gases, 1969.
NTIS: PB 198 252 :134 pages
This publication contains routine analyses and related source data for 390 natural gas samples from 22 states and five foreign countries. Of this total, 385 samples were collected during calendar year 1969. The remaining five analyses are of samples collected during previous years, but releases granting permission to publish the results were not received until 1969. All samples were collected 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 in this report were made by mass spectrometer and a special helium analysis apparatus which are described in Bureau of Mines bulletins 486 and 576. Eleven previous publications have presented the results of 8,660 gas analyses made by the Bureau of Mines Helium Activity prior to 1969. (Out of print.)
