I will now turn the call over to Glenn Darden to review our financial and operating activities in detail.
Glenn M. DardenThanks, John. Good morning. Quicksilver Resources earned $49 million or $0.28 per diluted share in the fourth quarter of 2011. Full year 2011 net income was $115 million or $0.67 per diluted share. This compares to $1.82 and $2.52 per diluted share for the respective periods in 2011. Each year was impacted by special items: in 2011, the sale of the BreitBurn units; and in 2010, the sale of our interest in Quicksilver Gas Services. Phil Cook, our CFO, will break this out in detail in his remarks. Quicksilver grew production 16% in 2011 versus 2010 volumes and replaced 165% of production. As drilling slowed down due to lower gas prices, we allocated capital to 2 grassroots oil projects: adding acreage to our Colorado position, which I'll talk about in a moment; and building new acreage basins in the Permian and Delaware Basins. These areas look very prospective for long-term growth. In Colorado, where we have assembled 210,000 acres in what we have now have established the oil window of the Niobrara, our initial drilling results have looked better with additional production run time. We have drilled and completed 6 wells testing the Niobrara, the last of which is a horizontal well. All of these wells are producing oil. We completed the first 3 vertical wells with oil fracs and the second 3 wells, 2 vertical and the horizontal, with a different style gas frac.
