ANNUAL REPORT OF THE ORIGIN OF NATURAL GAS LIQUIDS PRODUCTION

FORM EIA-64A

SURVEY YEAR 2012

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, 2012. If a plant was

operated during any part of survey year 2012, a Form EIA-64A 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, 2012 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 EIA-64A for each gas processing plant. If you had a plant in operation as of December 31, 2012 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 EIA-816, 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 19, 2013 for the 2012 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.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.

Completed forms may be submitted by Secure File Transfer, email, fax, or mail.

DATA STANDARDS

1. Total Operated Basis

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.

2. Units of Measurement

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.

EXAMPLES:

For Liquids: 7,500 barrels as: 8 MBbls

467 barrels as: 0 MBbls

For Gas: 8,500,000 cubic feet or 8,500 MCF as 9 MMCF

10,459,000 cubic feet or 10,459 MCF as 10 MMCF

ORIGIN OF NATURAL GAS RECEIVED
and
NATURAL GAS LIQUIDS PRODUCED

Report the total volume of natural gas received by this natural gas processing plant and the natural gas liquids extracted from this gas during the survey year. These total volumes should further be attributed to the State(s) or State subdivision(s) of origin as accurately as possible.

Lines 4.1 through 4.7 Area of Origin Code, Column (A): Indicate the area of origin as specified in the list of Areas of Origin Codes (page 6) and Subdivision Maps (page 7). Please enter the correct four-letter/number code for each geographic area that contributed gas to be processed during the survey year. If there are more than seven areas of origin involved for the same plant, complete an additional Form EIA-64A schedule and return the two schedules as one filing.

Lines 4.1 through 4.7 Natural Gas Received (MMCF), Column (B): Estimate as accurately as possible the volumes of gas, in millions of standard cubic feet (MMCF), received for processing by area of origin. Report these volumes in Column (B) adjacent to the appropriate Area of Origin Code in Column (A). These estimates should consider all relevant information available to the respondent and should be as precise as possible. Do not include refinery off gases. The total gas processed by the plant during the survey year should be entered on line 4.8. The sum of the volumes that were reported on lines 4.1 through 4.7 should be the same as the total volume reported on line 4.8. (See Natural Gas in the Glossary, page 4).

Lines 4.1 through 4.7 Natural Gas Liquids Production (MBbls), Column (C): Estimate as accurately as possible the gross volume of natural gas liquids in thousands of barrels (MBbls) attributable to the gas volumes reported in Column (B). Enter these amounts on the appropriate line of Column (C). The estimates of natural gas liquids recovered by area of origin should consider, to the fullest extent practical, all information available to the respondent concerning the relative liquid yields of the gas processed. Include only liquids production resulting from on-site gas processing. Include all volumes of plant condensate and scrubber oil recovered from natural gas at the plant.

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)

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.

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).

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 Conversion Factor

(MCF/Bbl or MMCF/MBbls)

Methane* 2.468

Ethane 1.558

Propane 1.499

Isobutane 1.245

Normal Butane 1.288

Isopentane 1.095

Natural Gasoline 0.940

Plant Condensate 0.940

Other Products 0.940

*Not an NGL

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.

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 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

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.

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.

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.

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.

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.

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.

Natural Gas Plant Liquids: Those hydrocarbons in natural gas that are separated as liquids at natural gas processing plants, fractionating and cycling plants, and in some instances, field facilities. Lease condensate is excluded. Products obtained include liquefied petroleum gases (ethane, propane, and butanes), pentanes plus, and isopentane. Component products may be fractionated or mixed.

Production, Natural Gas Liquids: Those hydrocarbons in natural gas that are separated from the gas through the processes of absorption, condensation, adsorption or other methods in gas processing or cycling plants. Generally such liquids consist of propane and heavier hydrocarbons and are commonly referred to as condensate, natural gasoline and liquefied petroleum gases. Where hydrocarbon components lighter than propane are recovered as liquids, these components should also be included with natural gas liquids.
