Analysis of Natural Gases, 1917-74.
NTIS: PB 251 202 :893 pages
This document contains 10,562 analyses of gas samples from oil and gas wells and natural gas pipelines in 37 states and 23 foreign countries. These gas samples were collected in the period 1917-74 as part of the Bureau of Mines survey for helium occurrences. The gas analyses contained in this printout were made by several methods over the period covered. Analytical work on samples collected in the period was done on the orsat apparatus. The one-cut apparatus and four-cut fractional distillation equipment were added later. In 1949, a mass spectrometer was acquired and was used for all gas analyses made after that time. Helium analyses throughout the period covered were made on special helium analytical equipment designed and built by the Bureau of Mines helium laboratory.
