Ultra Petroleum Provides Production and Capital Budget Guidance for 2008;
Increases 2009 Production and Provides Preliminary 2010 Guidance

HOUSTON, Feb. 19 /PRNewswire-FirstCall/ -- Ultra Petroleum Corp.
(NYSE: UPL) today reported that the company's Board of Directors' approved the
2008 capital budget of $755.0 million, an increase from $714.5 million of
capital spent in 2007.
Domestic production for 2008 is expected to grow approximately 18 - 22
percent to 135.0 - 140.0 Bcfe as compared to 114.4 Bcfe for 2007. All
production growth is generated organically. In 2008, the company is planning a
near doubling, from 2007 levels, of the number of delineation wells it expects
to drill. As part of its five year 120 well delineation drilling plan, 26 will
be drilled in 2008.

At this time, Ultra is increasing its previous 2009 production guidance of
160.0 - 165.0 Bcfe to 170.0 - 175.0 Bcfe, targeting a 25 - 30 percent increase
over 2008 at similar capital expenditures levels. In addition, the company is
providing preliminary production guidance for 2010 of 200.0 - 205.0 Bcfe,
targeting production growth of 18 - 21 percent. With more access anticipated
in 2009, associated with the satisfactory conclusion of the SEIS/ROD process
currently underway, these capital budget and production forecasts will be
increased.

"In 2008, we expect to drill 240 gross (113 net) wells in Wyoming. But,
more importantly, we will accelerate our delineation well drilling plans. It
is extremely important for us to continue defining the Pinedale Field so we
can get our arms around the actual size of the resource. We are planning
2008's drilling program with about 20 percent of our net wells to be devoted
to delineation," commented Michael D. Watford, Chairman, President and Chief
Executive Officer. "These wells cost more to drill and take longer, but are
instrumental to resource expansion and key to value creation. We look forward
to more reserves and more value at year-end 2008," added Watford.
