                      an interstate sale for resale or transportation service
                      or the facilities used to render those services.

	Definition:   The estimated productive capacity at any given point in
                      time, carrying forward for future use any productive
                      capacity resulting from an earlier excess of productive
                      capacity over production.
Affiliated Marketer
	Synonym:
	Definition:   Marketing company owned either by an interstate pipeline
                      or by a parent corporation that also owns an interstate

                      a pipeline pays to a producer affiliated with a pipeline
                      exceeds that paid to non-affiliated producers.
Agent
	Synonym:      Seller, Buyer or Shipper Representative
	Definition:   A legal representative of buyers, sellers or shippers of
                      natural gas in negotiation or operations of contractual

Allocation, Capacity
	Synonym:      Nomination Allocation
	Definition:   A process by which capacity available in a pipeline is
                      distributed to parties in the event requests for volume
                      (i.e., nominations and service contract requests) are in
                      excess of the available capacity.  Typical allocations
                      are based on criteria such as service type, contract
                      type, cost of service and date of first deliveries, all
                      as specified in the pipeline's tariff.
Allocation Formula
	Synonym:
	Definition:   The method used to allocate the total estimated or
                      actual flow at a custody transfer point.  The method
                      should be determined prior to gas flow.  Methods
                      include:  prorata to all shippers based on confirmed
                      nominations; utilize a swing contract for all over and
                      under volumes; record all production in excess of
                      confirmed nominations in a suspense account for future
                      nomination with the operator; use a balancing agreement
                      to record all volumes over and under the confirmed
                      nomination at the point of custody transfer.
Allocation, Measurement
	Synonym:
	Definition:   The assignment of a total measured quantity of gas at a
                      point to the various contracts active at that point
                      during a specific period of time.
Allocation Methods
	Synonym:
	Definition:   Balancing Agreement - A method whereby all shippers are
                      guaranteed confirmed nominations at the meter and any
                      variance between the aggregate confirmed nominations and
                      measured volumes held between the interconnecting
                      parties.
		      Entitlement - This method utilizes production ownership
                                    as the basis for allocation at production
                                    points with multiple ownership and/or
                                    property specific contract commitments.
		      Prorata - A method that involves the allocation of
                                actual pipeline receipts to all shippers
                                strictly on the basis of confirmed
                                nominations, with all shippers receiving a
                                prorata share of any over or under volumes
                                measured through the meter.
		      Suspense - The suspense method provides for the
                                 allocation of measured volumes only in excess
                                 of confirmed nominations.  Shippers are
                                 allocated exactly the confirmed nomination
                                 and the excess production is held in a
                                 suspense account for future resolution.
		      Swing - A designated party(ies) is identified to take
                              the "swing" at a meter point; that is, any
                              variance between the aggregate confirmed
                              nominations and measured volume.  A swing method
                              differs from a balancing method in that the
                              imbalance is assigned to the pipeline and
                              shipper(s) as opposed to interconnecting
                              parties.
Allocation of Costs
	Synonym:
	Definition:   Cost Allocation is the process of allocating the
                      Functionalized/Classified Costs to each customer service
                      provided by the pipeline using allocation units or
                      factors such as demand volume, throughput and distance.
Allocation, Sales
	Synonym:      Curtailment
	Definition:   The process by which a seller assigns supplies to
                      purchasers when total sales requests exceed the seller's
                      total supply.  Priorities typically based on contract
                      type and price.
Allocation Units/Factors

	Definition:   Factors used in the Toll Design Calculation to allocate
                      costs to various services (e.g., demand volume

                      wells that is allowed by a particular state or governing

                      various states or governing bodies.

	Synonym:      AQE, Annual Contract Quantity (ACQ)
	Definition:   The quantity of gas a buyer or shipper has nominated to
                      receive on an annual basis from a pipeline.

	Definition:   The coordinating organization for America's federated
                      national standards system.  The ANSI federation consists
                      of nine hundred companies, large and small, and some two
                      hundred trade, technical, professional, labor and

                      maintaining U.S. standards for business-to- business
                      electronic data interchange pertaining to trade
                      transactions, with business-to-business defined broadly
                      to include all organizations, but excluding all
                      individual consumers.
Application
	Synonym:
	Definition:   A formal request made by a utility to change rates or
                      condition of service, which requires hearing before a
                      regulatory body.
Area Rate Clause
	Synonym:      Escalator, Indefinite Price Escalator
	Definition:   A contract provision that allows for increases in the
                      price paid for gas over the term of the agreement if gas
                      rates in the production area escalate.
As-Billed Rates
	Synonym:
	Definition:   A policy allowing pipelines to flow through gas costs to
                      their customers in the same manner as they are billed to
                      the pipeline.  (For example, demand charges paid by the
                      pipeline would be included in demand charges billed to
                      its customer; commodity charges would be flowed through
                      in the same way.)  Currently Canadian suppliers want to
                      flow their charges through to U.S. customers on an
                      "as-billed" basis.  FERC has declared those charges
                      should be billed to U.S. customers using U.S. ratemaking
                      formulas (FERC Opinion 256).  U.S. producers think the
                      "as-billed" treatment gives Canadian gas an unfair
                      competitive advantage by loading up the demand charge
                      and cutting commodity rates, while Canadians argue that
                      the rate is based on contractual agreements worked out
                      years ago - agreements based on the cost of building
                      facilities in Canada to serve the U.S. market.

	Synonym:      Solution Gas
	Definition:   Natural gas found in contact with or dissolved in crude
                      oil in the reservoir.  Can be further categorized as
                      (1)Gas Cap Gas which is free natural gas, which overlies

                      (2) Solution Gas which is natural gas dissolved in crude
                      oil in the reservoir at the prevailing conditions of
                      pressure and temperature.
