Petal Gas Expansion Gets FERC Nod

FERC last week gave Petal Gas Storage the go-ahead to double the certificated capacity of its storage facilities in Mississippi to 10.4 Bcf. Petal Gas would accomplish this by drilling, leaching and developing a second underground salt dome storage cavern identical to its existing cavern. The proposed storage cavern would have the same certificated capacity as the existing cavern (5.2 Bcf), and both would have a combined actual working gas capacity of 5.8 Bcf.

Gas could be injected into the combined storage facilities at an average rate of 160 MMcf/d, allowing shippers to fill the working gas capacity in 40 days. And it could be withdrawn from the two caverns at an average rate of 640 MMcf/d, enabling shippers to pull out their gas completely in 10 days.
