Background

  • Exxon argues the LaBarge Field wellhead meters are custody transfer meters, determining Exxon’s point of valuation for its gas production.
  • Wyoming Amoco decisions define custody transfer meter and guide valuation Point; Amoco (2004) clarifies meter transfer concepts.
  • Board held the meters are not custody transfer meters for Exxon, since Exxon retains custody before and after measurement at the meters.
  • Board held the meters are custody transfer meters for Howell and Yates because their gas is transferred to Exxon for processing at the meters.
  • Howell and Yates were not parties to the action and did not appeal the Department’s valuation; issues regarding their gas were not properly before the Board.
  • Court ultimately affirms the Board on Exxon’s gas but reverses on Howell and Yates due to lack of party status and proper Board authority.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Are the wellhead meters custody transfer meters for Exxon’s gas? Exxon contends meters transfer custody and control at the meters. Board held meters are not custody transfer meters for Exxon. Meters are not Exxon custody transfer meters.
Did the Board have authority to decide the valuation point for Howell and Yates' gas? Board can determine valuation points for all gas in LaBarge. Howell and Yates were not parties and issues were not properly before Board. Board authority over non-parties was lacking; Howell and Yates issues reversed.
Was Howell and Yates' gas properly before the Board as aggrieved parties? Howell and Yates should be considered for their gas valuation. Howell and Yates were not aggrieved parties appealing; Board lacked jurisdiction over them. Howell and Yates were not aggrieved parties; issues not properly before Board.
