National Fuel Gas Supply Corporation Submits Semi-Annual Report for Beech Hill Storage Field

The National Fuel Gas Supply Corporation has submitted a semi-annual report to the Federal Energy Regulatory Commission (FERC) for the period of January 1, 2025, to June 30, 2025. The report covers the operations of the Beech Hill Storage Field in Allegany County, New York, and addresses the containment of storage gas within the reservoir. The corporation has continued to implement its containment plan, including limiting gas injections, managing withdrawals, and monitoring containment through data from observation wells.

Key Takeaways:

• The corporation has continued to limit gas injections into the wells closest to the Beech Hill Annex, with injected gas volumes totaling 1.50 Bcf during the reporting period.
• National Fuel has managed withdrawals from the Beech Hill Annex, with 348,293 MCF withdrawn during the reporting period.
• The corporation has monitored containment through data from observation wells, with 12 of the 14 Oriskany observation wells within the buffer exhibiting pressures under 150 psig.
• The formation fluids in the structural low help keep the storage gas contained within the Beech Hill Complex.
• East Independence well EC432 has increased in pressure from 639 to 690 psig during the reporting period, indicating the slow accumulation of native gas as it comes out of solution.
• Withdrawal from Beech Hill well 7451 was discontinued in May of 2023, and National Fuel monitors Shongo pool pressures at this well.
• The corporation will continue to review data from the Greenwood storage field and update the plan as needed.

Statistics:

• 1.50 Bcf: injected gas volumes into the wells closest to the Beech Hill Annex during the reporting period.
