XTO Energy increases 2007 production target

United States based XTO Energy Inc. has updated operational and financial guidance based on current expectations for production, expenses, and other parameters resulting from ongoing operations and development budget activities. These statements are forward looking, as described in the final paragraph of this release, and actual results may differ materially.

These estimates do not include derivative fair value gains and losses, the effects of other possible future acquisitions or divestitures, or unforeseen events that may occur after this.

The Company is targeting annual production growth of 18% for 2007 and is increasing its production growth target to 17% from 15% for 2008. The Company’s realized natural gas and oil prices are expected to average below the NYMEX prices due to regional differentials.

Realized pricing for natural gas liquids (NGL) is expected to be about 55% to 65% of the average NYMEX oil price.
