ANNUAL REPORT OF THE ORIGIN OF NATURAL GAS LIQUIDS PRODUCTION
FORM EIA-64A
SURVEY YEAR 2009

GENERAL INSTRUCTIONS
PURPOSE
The collection of basic, verifiable information on the Nation's
reserves and production of natural gas liquids (NGL) is
mandated by the Federal Energy Administration Act of 1974
(FEAA) (Public Law 93-275) and the Department of Energy
(DOE) Organization Act of 1977 (Public Law 95-91). The
data collected on the Energy Information Administration (EIA)
Form EIA-64A includes the annual volumes of natural gas
received, and natural gas liquids extracted at gas processing
plants by areas of origin. It also includes the total gas
shrinkage resulting from the natural gas liquids extracted and
the annual volume of natural gas utilized as fuel at the gas
processing plants.
Gas shrinkage volumes reported by natural gas processing
plant operators on Form EIA-64A are used with natural gas
data collected on a "wet after lease separation" basis on
Form EIA-23, Annual Survey of Domestic Oil and Gas
Reserves, to estimate "dry" natural gas reserves and
production volumes regionally and nationally. The shrinkage
data are also used, along with the plant liquids production
data reported on Form EIA-64A and lease condensate data
reported on Form EIA-23, to estimate regional and national
gas liquids reserves and production volumes. This
information is the only comprehensive source of credible
natural gas liquids data and is required by DOE to assist in
the formulation of national energy policies.
The information collected on Form EIA-64A will be used:
• as key input to the EIA publication entitled U.S. Crude
Oil, Natural Gas and Natural Gas Liquids Reserves;
• to estimate extraction loss volumes contained in the EIA
publication Natural Gas Annual
• as the replacement for the natural gas liquids data which
were published in the past by the American Petroleum
Institute (API) and the American Gas Association (AGA)
in their annual statistical reports entitled, Reserves of
Crude Oil, Natural Gas Liquids, and Natural Gas in the
United States.

WHO MUST SUBMIT
Each operator of one or more domestic natural gas
processing plants is required to file a Form EIA-64A for each
plant operated as of December 31, 2009. If a plant was

operated during any part of survey year 2009, a Form EIA64A must be submitted for that plant. In cases in which two
or more operators during the survey year operated a plant,
the operator as of December 31, 2009 should file a Form
EIA-64A that covers the entire survey year.
If the current operator is unable to obtain from previous
operators the information required to compile accurate data
covering the entire survey year, then each operator should
file a Form EIA-64A covering only that portion of the survey
year during which he operated the plant.
If there is some question whether a plant is a "natural gas
processing plant" or "field separation facility," contact your
company's responsible preparer of Form EIA-23, Annual
Survey of Domestic Oil and Gas Reserves, in order to
internally coordinate your responses. This will ensure that
double reporting or non-reporting of natural gas liquids data
does not occur.

WHAT MUST BE SUBMITTED
Each operator is required to complete a separate Form EIA64A for each gas processing plant. If you had a plant in
operation as of December 31, 2009 and did not receive a
Form EIA-64A for it, a completed form should still be filed for
that plant. Respondents need submit only one copy of the
completed form for each plant. Form EIA-64A solicits annual
data separated by area of origin not required on Form EIA816, Monthly Natural Gas Liquids Report. Form EIA-64A
does not replace or supersede Form EIA-816 that is still
required on a monthly basis.

WHEN AND WHERE TO SUBMIT
Form EIA-64A must be completed and submitted to EIA on
or before April 1, 2010 for the 2009 calendar year.
To facilitate the processing of data, the use of EIA forms is
requested (either hardcopies or Excel spreadsheets).
Additional copies of the EIA-64A form and instructions are
available in PDF or XLS format on the EIA website
http://www.eia.doe.gov/oss/forms.html#eia-64a.
Computer
printouts on other than an exact duplicate of the form
provided are not acceptable. Photocopies of the form may be
used.

DATA STANDARDS
RECORD KEEPING REQUIREMENTS

1. Total Operated Basis

You are required to keep all records necessary to reconstruct
the data reported on this form for a period of three (3) years.

All data are to be reported on a total operated basis
(commonly known as the "gross operated" or "8/8ths" basis)
by the operator of the natural gas processing plant.

SANCTIONS

2. Units of Measurement

The timely submission of Form EIA-64A by those required to
report is mandatory under Section 13 (b) of the Energy
Information Administration Act of 1974 (FEAA) (Public Law
93-275), as amended. Failure to respond may result in a civil
penalty of not more than $2,750 a day for each violation or a
fine of not more than $5,000 a day for each willful violation.
The government may bring a civil action to prohibit reporting
violations that may result in a temporary restraining order or
a preliminary or permanent injunction without bond. In such
civil action, the court may also issue mandatory injunctions
commanding any person to comply with these reporting
requirements.

Natural gas liquid volumes are to be reported in thousands of
barrels (MBbls) of 42 U.S. gallons at 60° Fahrenheit. Natural
gas volumes are to be reported in millions of cubic feet
(MMCF) at 14.73 psia and 60° Fahrenheit.

3. Rounding
Liquid volumes should be rounded to the nearest thousand
barrels. When rounding liquid volumes, round quantities of
500 barrels and above to the next higher MBbl and round
quantities of less than 500 barrels down to the next lower
MBbl. Similarly, when rounding natural gas volumes, round
quantities of 500 MCF and above to the next higher MMCF
and round quantities of less than 500 MCF down to the next
lower MMCF.

Line 4.8 Report the total natural gas liquids that were
recovered from the natural gas processed by the plant during
the survey year. The sum of the volumes reported on lines
4.1 through 4.7 should be the same as the total volume on
line 4.8. This total should also equal the sum of the monthly
volumes of "Production During Month" minus the sum of
monthly volumes of "Inputs During Month" reported on Form
EIA-816, Monthly Natural Gas Liquids Report. (See Natural
Gas Liquids in the Glossary, page 4)

other type of fuel, such as electricity, report 0 (zero) and
indicate the reason in Section 7.0, Comments.
Item 7.0 Comments: You may comment on any reported
data item in order to enhance its clarity. If additional space is
needed to continue comments, report them on another sheet
of paper of equal size and attach it to the form.

GLOSSARY

Item 5.0 Gas Shrinkage Resulting from Natural Gas
Liquids Extracted: Estimate the volumes of gas shrinkage
in millions of cubic feet (MMCF) resulting only from the
removal of natural gas liquids from the natural gas received
at the plant. Do not include gas shrinkage attributable to
non-hydrocarbon gases, gas used for fuel, gas which was
vented or flared, or gas which was unaccounted for.

Natural Gas: A gaseous mixture of hydrocarbon
compounds, the primary one being methane. Note: The
Energy Information Administration measures wet natural
gas
and
its
two
sources
of
production,
associated/dissolved natural gas and non-associated
natural gas, and dry natural gas, which is produced from
wet natural gas.

The ratio of the shrinkage volume to the total plant NGL
volume reported in Line 4.8 (Column C) should range
between 1.558 MMCF per thousand barrels and about 0.940
MMCF per thousand barrels. These are the approximate
vapor equivalents for pure ethane and for natural gasolines
and plant condensate, respectively (see table below).

Note: The parameters for measurement are cubic feet at 60
degrees Fahrenheit and 14.73 pounds per square inch
absolute (psia).
Associated-dissolved natural gas: Natural gas that
occurs in crude oil reservoirs either as free gas
(associated) or as gas in solution with crude oil
(casinghead gas). See natural gas.

Calculate the equivalent gas volumes for the natural gas
liquids components by multiplying the specific liquid product
by the appropriate conversion factor listed in the table below.
Component or Product
Methane*
Ethane
Propane
Isobutane
Normal Butane
Isopentane
Natural Gasoline
Plant Condensate
Other Products
*Not an NGL

Dry natural gas: Also known as consumer-grade natural
gas. The natural gas that remains after:
• the liquefiable hydrocarbon portion has been
removed from the gas stream (i.e., gas after lease,
field and/or plant separation)
• any volumes of non-hydrocarbon gases have been
removed where they occur in sufficient quantity to
render the gas unmarketable.

Conversion Factor
(MCF/Bbl or MMCF/MBbls)

1.499
1.245
1.288
1.095
0.940

Non-associated natural gas: Natural gas that is not in
contact with significant quantities of crude oil in the
reservoir.
Wet natural gas: A mixture of hydrocarbon compounds
and small quantities of various non-hydrocarbons existing
in the gaseous phase or in solution with crude oil in
porous rock formations at reservoir conditions. The
principal hydrocarbons normally contained in the mixture
are methane, ethane, propane, butane, and pentane.
Typical non-hydrocarbon gases that may be present in
reservoir natural gas are water vapor, carbon dioxide,
hydrogen sulfide, nitrogen and trace amounts of helium.
Under reservoir conditions, natural gas and its associated
liquefiable portions occur either in a single gaseous
phase in the reservoir or in solution with crude oil and are
not distinguishable at the time as separate substances.
Note: The Securities and Exchange Commission and The
Financial Accounting Standards Board refer to this
product as natural gas.

Conversion factors for other natural gas liquid components
may be obtained from the EIA-64A Coordinator toll-free at
800-879-1470 between 8:00 a.m. and 4:30 p.m. Central
Time.
EXAMPLE: To convert 50,000 barrels of propane to the
equivalent gas volume:
(50,000 barrels) times (1.499) = 74,950 MCF
OR utilizing the correct reporting units:
(50 M Barrels) times (1.499) = 74.95 or 75 MMCF.
After converting each of the individual plant components or
products (i.e., ethane, propane, isobutane, normal butane,
isopentane, natural gasoline, plant condensate, and other
products) to their equivalent gas volume, they should then be
summed to determine the total plant shrinkage volume.

Natural Gas Processing Plant: Facilities designed to
recover natural gas liquids from a stream of natural gas that
may or may not have passed through lease separators
and/or field separation facilities. These facilities also control
the quality of the natural gas stream to be marketed. Cycling
plants are classified as natural gas processing plants.

Item 6.0 Natural Gas Used as Fuel in Processing
(MMCF): Report the volume of natural gas utilized as fuel at
the natural gas processing plant. If fuel use was not metered,
please provide your best estimate. If the plant utilizes some

Operating Company Name: The Company responsible for
the management and day-to-day operation of one or more
natural gas processing plants as of December 31 of the
survey year. The operator is generally a working interest
owner or a company under contract to the working interest
owner(s). Plants shut down during the survey year are also
considered "operated" as of December 31.
