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

CALGARY, ALBERTA, May 20 (MARKET WIRE) --
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.
