Questar has revised 2008 earnings and production guidance and underlying assumptions to incorporate newly acquired properties, the recent increase in natural gas and crude oil prices, and additional natural gas fixed-price hedges.

Questar E&P has now hedged about 78% of forecast natural gas and oil-equivalent production for the remainder of 2008 with fixed-price swaps. Additionally, the company has hedged about 2% of its forecast natural gas production for the remainder of 2008 with basis-only swaps.

The company estimates that a $1.00 per MMBtu change in the average NYMEX price of natural gas for the remainder of 2008 would result in about a $0.02 change in earnings per diluted share.

A $10.00 per bbl change in the average NYMEX price of oil for the remainder of 2008 would result in about a $0.05 change in earnings per diluted share.

"We're now in a position to grow Questar E&P production 14 to 16% in 2008," said Chuck Stanley, Questar COO and head of the company's exploration and production businesses. "We've also taken advantage of the recent jump in natural gas prices to hedge additional Questar E&P production to lock in attractive returns on invested capital and cash flows, both from the newly acquired properties and from our existing assets." The company has added 11 Bcf of natural gas fixed-price swaps for the remainder of 2008, 28.1 Bcf for 2009, and 28.4 Bcf for 2010 since it last disclosed hedge positions on February 12, 2008.
