ENSTOR Announces Expansions to Two Key Gas Storage Facilities

January 2011 Vol. 238 No. 1

“ENSTOR continues to invest in facility expansion through the addition of interconnects or by increasing capacity in locations where market conditions are favorable,” said Pat DeVille, president of ENSTOR.

The high-deliverability, multi-cycle Caledonia facility has increased its maximum certificated working gas capacity from 16.9 Bcf to 22 Bcf. That pushes maximum daily withdrawal rates to 550,000 Mcf/d and the maximum injection rate to 558,000 Mcf/d.

Caledonia is connected to Tennessee Gas Pipeline on its 500 Leg in Zone 1, and is located in an area traversed by numerous new and existing interstate pipelines which access the prolific Barnett, Woodford and Haynesville shale production areas. Additionally, this pipeline serves markets in the Northeast, Southeast and Ohio Valley regions.

The Grama Ridge facility – which offers low-turn storage suitable for managing seasonal and operational needs in the Permian region – also has expanded by more than 2 Bcf to in excess of 9.5 Bcf of capacity. By year end Grama Ridge completed an additional pipeline interconnect with NGPL with an incremental 35,000 MMBtu/d of access to Permian and MidContinent supply basins, with the potential for expansion to 150,000/d.

Grama Ridge is interconnected with the El Paso pipeline in the Keystone pooling area and with DCP’s Raptor Pipeline.
