Of the total samples, 381 were collected during calendar years 2002 through 2004. The analyses were done using gas chromatography. None of the analyses have been published previously in other analyses reports. All samples were obtained and analyzed as part of the United States Department of the Interior’s Bureau of Land Management investigations of the occurrences of helium in natural gases of countries with freemarket economies. The results of these investigations are published periodically to make the information available to members of the helium and petroleum industries and to the general public. Introduction periodically by information circulars and technical notes (4–17, 19–24, 26–30, 32– 36, 38–43) containing 11,151 analyses of samples collected since 1960. Bureau of Land Management Technical Note 418, Analyses of Natural Gases, 2002– 2004, contains analyses and related source data for 451 natural gas samples from 15 States. Of the total samples, 381 were collected during calendar years 2002 through 2004. The remaining 70 were collected earlier, but releases granting permission to publish them were received at a later date. None of these analyses have been published previously in other analyses reports. In 1976, a compilation of the analyses made prior to 1975 was prepared by the United States Bureau of Mines (USBM) and published by the National Technical Information Service of the United States Department of Commerce (18). The 1976 compilation contains 10,562 analyses of gas samples from gas and oil wells and natural gas pipelines in 37 States and 23 foreign countries. The analyses were done using gas chromatography. All samples were obtained and analyzed as part of the Bureau of Land Management investigations of the occurrences of helium in natural gases of countries with free-market economies. This helium survey program has been conducted since 1917. The results are published periodically to make the information available to members of the helium and petroleum industries and to the general public. Three other compilations of analyses have been published (25, 31, 37) by the USBM. The first of these was published in 1982 and contained analyses performed prior to 1981. The 1982 publication contains 12,554 analyses of gas samples from gas and oil wells and natural gas pipelines in 39 States and 24 foreign countries and includes the analyses from the 1976 publi cation (25). The second of these compila tions was published in 1987 and contains 14,242 analyses performed prior to 1986. The samples were taken from gas and oil wells and natural gas pipelines in 40 States and 24 foreign countries (31). In 1991, a compilation of analyses was completed as a supplement to the 1987 publication and contains all analyses published from 1986 through 1990. The 1991 publication Forty-three publications have presented the results of 16,369 gas analyses performed through 2001. These publications are refer enced at the end of this report in the sec tion “Previous Publications in the Helium Survey Series.” The first three bulletins (1–3)1 contain analyses and related source data on 5,218 gas samples collected from 1917 through 1960. These bulletins have been supplemented 1The numbers in parentheses refer to items in the list of previous publications at the end of this report. Analyses of Natural Gases, 2002–2004 contains 920 samples from gas and oil wells and natural gas pipelines in 26 States and 2 foreign countries (37). Technical Note 418 for purchase around the time this report is published. The helium survey program is conducted by soliciting natural gas samples from throughout the United States and other countries with free-market economies. The helium survey, in its present scope, would not be possible without the assistance of the helium and petroleum industries, State and Federal agencies, and the many indi viduals engaged in oil and gas exploration and production. In addition to appearing in the publica tions, all analyses and related information published through 2001 are available on CD-ROM from the National Technical Information Service (NTIS) in Springfield, Virginia (1-800-553-NTIS). Orders should refer to Bureau of Land Management CD-ROM PB2004-500040. The update to this CD-ROM, which will include the 2002–2004 analyses, should be available Ta b l e s Tables 1 and 2—the main focus of this technical note—include the results of analyses and related source data from the gas samples. This information is divided into two groups. Table 1 contains information on samples from gas and oil wells in the United States. Table 2 contains information on samples from natural gas pipelines in the United States. The following chart Source Number of Samples indicates the sources of the samples listed in these tables. All components of the analyses in the tables are reported to the nearest 0.1 percent, except helium, which is reported to the nearest 0.01 percent. The word “trace” is used to denote quantities of helium of less than 0.005 percent and quantities of other components of less than 0.05 percent.

Because not all of the provinces shown are gas-producing areas, many of the codes are not used in this publi cation. In addition, since State or Federal ownership is not always known in offshore areas, only one code is used for each State. Due to the lack of information on the loca tion of wells in Alaska, only one code (972) is used for all wells. Tables 1 and 2 also include geologic province codes so each sample source can be located within a specific geologic province as defined by the Committee on Statistics of Drilling of the American Association of Petroleum Geologists. The provinces and their associated codes are provided in the list that follows and are also illustrated in Figure 1.2 They are 2 The list and Figure 1 are taken from the article cited as: Meyer, R.F. 1970.
