XTO ENERGY ACQUIRES PRODUCING PROPERTIES IN

THE EAST TEXAS, ARKOMA AND SAN JUAN BASINS

FORT WORTH, TX (October 15, 2003)—XTO Energy Inc. (NYSE-XTO) announced today that it has completed property transactions which increase its positions in Texas, Arkansas, New Mexico and Colorado for a total cost of $100 million. The purchases have been funded by existing credit facilities. XTO Energy’s internal engineers estimate proved reserves to be 83 billion cubic feet of gas (Bcf) of which 60% are proved developed. The acquired properties will contribute about 12.7 million cubic feet per day (MMcfd) of gas production during the fourth quarter.

“Our acquisition efforts continue to yield tactical assets for XTO’s long-term strategy,” says Bob R. Simpson, Chairman and Chief Executive Officer. “We are adding high-quality properties, long-lived with strong margins and low-risk upsides, in our key operating areas. When combined with the largest development inventory in the Company’s history, the result is an outlook for steady growth.”

Steffen E. Palko, Vice Chairman and President continued, “This package of properties reflects our acute focus on acquiring the right properties for the Company. In East Texas, we are adding 11,000 gross or 8,000 net acres of development potential to our prolific Freestone Trend. The purchase in the Arkoma Basin increases our ownership in growth assets and the San Juan Basin interests build on our stronghold of producing properties in both conventional and coalbed-methane gas production. Altogether, these acquisitions provide attractive economics, production decline management and new inventory to drill.”

In East Texas, XTO purchased 42 Bcfe of reserves (38% proved developed) in Freestone and Limestone counties. Gas sales from these properties currently total 4.0 MMcfd (net). The 11,000 gross acres acquired also includes a processing plant with 35 MMcfd in gas processing capacity. The transaction was effective October 1, 2003.

In the Arkoma Basin, the Company acquired 19 Bcfe of reserves (88% proved developed) in Franklin,

Logan, Pope and Sebastian counties. The interests produce about 4.3 MMcfd (net) of natural gas with the majority focus in Aetna Field. The transaction was also effective October 1, 2003.

In the San Juan Basin, XTO added another 22 Bcfe of reserves (78% proved developed) in New Mexico and Colorado. Effective July 15, 2003, the interests contribute 4.4 MMcfd (net) of gas production, with about 70% attributable to the prolific Fruitland Coal formation.
