Enterra Energy Trust Moves U.S. Head Office to Oklahoma City

CALGARY, ALBERTA--(Marketwire - May 20, 2008) - Enterra Energy Trust ("Enterra" or the "Trust") has relocated its U.S. head office to Oklahoma City, Oklahoma. The new office is located at Suite 325, 4801 Gaillardia Parkway in northwest Oklahoma City. The Trust's operational centre will remain in Carney, Oklahoma.

"Our team will benefit in many ways from a head office in the State capital, where the oil and gas industry has a long history and a well-established community," said John Chimahusky, Enterra's Senior Vice President and Chief Operating Officer, U.S. Operations. "The move helps us to more firmly establish Enterra's business presence in the State. With the current pace of drilling and the inventory of prospects available to us in Oklahoma, this new office is well suited to attract and retain high-calibre staff and offers convenient access to technical and financial services."

Operations in Oklahoma have consistently provided more than 40% of Enterra's overall production since the Trust acquired the assets in early 2006. There are approximately 70 drilling locations currently identified on over 48,000 undeveloped acres of land, and the Trust expects to participate in the drilling of up to 30 wells on Enterra's land in the area in 2008.
