The company reported first-quarter 2011 production of 24,775-barrel oil equivalent per day, increasing 19%, due to better-than-expected well performance at its Glacier property. Lower natural gas prices reduced operating cash flows to $40 million from $49 million in the same quarter the prior year. Capital expenditure during the first quarter of 2011 amounted to $77 million and the majority of capital spending was made at Glacier. The phase 3 development program at Glacier was ahead of schedule, which augurs well for future drill inventory. Management estimates production at around 23,500 boe/d for the second quarter of 2011. The stock has 43% upside over the next year with 67% analysts recommending a buy, as per a Bloomberg consensus.
