XTO Energy Inc. has recently acquired 24,000 net acres in the Barnett Shale from multiple parties for approximately $550 million. XTO Energy's internal engineers estimate proved reserves to be in excess of 200 billion cubic feet of gas equivalent.

The acquisitions will initially add about 25 million cubic feet of natural gas equivalent per day to the Company's growing production base. The Company has identified an additional 300-350 drilling locations on the properties for future development, which offer the potential to more than double reserves.

"Over the past three years, we have grown our Barnett production at better than a 50% compounded rate which continues to drive our ambitions to build-out XTO's footprint in the region," stated Keith A. Hutton, President. "This group of acquisitions is the ideal bolt-on investment, focusing in areas of our strongest well performance. The related drilling inventory and upside potential extends our double-digit growth profile in the area. Our position in the Barnett Shale play now includes about 240,000 net acres, with approximately 50% situated in the prolific core area, where the geology of the shale offers the best productivity potential. We intend to operate about 20 drilling rigs to consistently and continuously develop our shale acreage. This year, we have invested over $300 million in compression, processing and pipeline infrastructure to establish a dominant position in the play which will grow for years to come. These properties immediately add to our production and we are now targeting 17% growth in 2008 for the Company."
