Technical Note 418 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 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.

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. 

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. 

Forty-three publications have presented the 

results of 16,369 gas analyses performed 

through 2001. These publications are referenced at the end of this report in the section “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 

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. 

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. 

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 publication (25). The second of these compilations 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 

I n t r o d u c t i o n

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 Technical Note 418



contains 920 samples from gas and oil 

wells and natural gas pipelines in 26 States 

and 2 foreign countries (37). 

In addition to appearing in the publications, 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 

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 individuals engaged in oil and gas exploration 

and production. 


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 

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.

2The list and Figure 1 are taken from the article cited as: Meyer, R.F. 1970. Geologic provinces code map 

for computer use: American Association of Petroleum Geologists Bulletin, v. 54, n. 7, p.1301-1305.

Geologic Provinces of the United 

States 

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 

delineated by political boundaries for convenience and for accommodation of the data 

processing equipment. Because not all of the 

provinces shown are gas-producing areas, 

many of the codes are not used in this publication. 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 location of wells in Alaska, only one code (972) 

is used for all wells.
