Exhibit 99.1

News release via Canada NewsWire, Calgary 403-269-7605

	    Attention Business Editors:
	    Penn West Energy Trust and Canetic Resources Trust announce the closing
	    of their combination and the creation of North America's largest
	    conventional oil and gas energy trust

	    CALGARY, Jan. 11 /CNW/ - (TSX - PWT.UN; NYSE - PWE) Penn West Energy
Trust ("Penn West") and (CNE.UN - TSX; CNE - NYSE) Canetic Resources Trust
("Canetic") are pleased to announce that the acquisition of Canetic by Penn
West pursuant to a plan of arrangement (the "Arrangement") was completed
today.
	    Under the Arrangement, Canetic Unitholders will receive 0.515 of a Penn
West trust unit for each Canetic trust unit exchanged. The exchange is
intended to be completed on a tax-deferred basis for Canadian and U.S. federal
income tax purposes except for those Canetic Unitholders who are subject to
Canadian federal income tax and who have validly elected to have the exchange
completed on a taxable basis. The first distribution that former Canetic
Unitholders will be eligible to receive from Penn West will be the
distribution payable on or about February 15, 2008 to Penn West Unitholders of
record on January 31, 2008. Canetic Unitholders of record at the close of
business on January 10, 2008 will also receive a special one-time distribution
of CDN $0.09 per Canetic trust unit. The special distribution, together with
the distributions payable on the Penn West trust units (assuming no changes to
the current distribution policies of Penn West), will effectively maintain the
equivalent of Canetic's pre-Arrangement monthly cash distributions to Canetic
Unitholders for six months following completion of the Arrangement, taking
into account the trust unit exchange ratio and the pre-Arrangement monthly
distribution levels of Penn West and Canetic. The special distribution will be
paid on or about January 17, 2008. Canetic units are expected to be de-listed
from the Toronto Stock Exchange (TSX) and the New York Stock Exchange (NYSE)
within a few trading days. Penn West trust units will continue to trade on the
TSX under the symbol PWT.UN and on the New York Stock Exchange (NYSE) under
the symbol PWE.
	    Under the Arrangement, Penn West has assumed all of the covenants and
obligations of Canetic in respect of the four separate classes of outstanding
Canetic convertible debentures ("Canetic Debentures"). Holders of Canetic
Debentures will now be entitled to receive 0.515 of a Penn West trust unit in
lieu of each Canetic trust unit that the holder was previously entitled to
receive on conversion. Outlined below are the revised conversion prices for
the Canetic Debentures: (i) Canetic 6.5 percent Debentures issued May 26, 2005
(CNE.DB.B - TSX) - $36.8155 per Penn West trust unit (27.1625 Penn West Units
per $1,000 principal amount); (ii) Canetic 6.5 percent Debentures issued
August 24, 2006 (CNE.DB.E - TSX) - $51.5534 per Penn West Unit (19.3974 Penn
West Units per $1,000 principal amount); (iii) Canetic 8.0 percent Debentures
issued June 15, 2004 (CNE.DB.C) - $30.2136 per Penn West Unit (33.0977 Penn
West Units per $1,000 principal amount); and (iv) Canetic 9.4 percent
Debentures issued July 3, 2003 (CNE.DB.A) - $31.1068 per Penn West Unit
(32.1473 Penn West Units per $1,000 principal amount). The Canetic Debentures
are anticipated to be de-listed within a few trading days and will be
subsequently renamed as Penn West Debentures and begin trading on the TSX as
PWT.DB.A in respect of the 9.4 percent July 2003 series, PWT.DB.B in respect
of the 8.0 percent June 2004 series, PWT.DB.D in respect of the 6.5 percent
May 2005 series and PWT.DB.F in respect of the 6.5 percent August 2006 series.
	    Former Canetic Unitholders who are resident in Canada or the United
States and who are interested in participating in the Penn West distribution
reinvestment plan (the "Penn West DRIP") should, if they are now a registered
Penn West Unitholder, complete and deliver an authorization form to CIBC
Mellon Trust Company (Penn West's registrar and transfer agent), and if they
are now a beneficial Penn West Unitholder, contact their broker, investment
dealer, financial institution or other nominee through which their Penn West
Units are held and provide instructions on how they wish to participate in the
Penn West DRIP. The authorization form for registered Penn West Unitholders
can be obtained at www.pennwest.com.
	    The combination of Penn West and Canetic has created the largest
conventional oil and gas energy trust in North America with an enterprise
value of approximately $14 billion, a significant portfolio of unconventional
opportunities and a dominant position in light oil in Canada. In addition, the
new Penn West has a diversified portfolio of conventional oil and natural gas
assets plus significant resource-play potential in the Peace River oil sands
of Northern Alberta, CO2 enhanced oil recovery in the Pembina, Swan Hills,
Midale and Weyburn light oil pools and coalbed methane producing assets. Penn
West is well positioned to create long-term value for Penn West Unitholders
through its high-quality, long-life asset base, a strong balance sheet, and an
extensive drilling inventory, together with improved access to equity and debt
markets resulting from Penn West's increased size and strength. Penn West
trust units and debentures are listed on the Toronto Stock Exchange under the
symbols PWT.UN, PWT.DB.A, PWT.DB.B, PWT.DB.C, PWT.DB.D, PWT.DB.E and PWT.DB.F
and Penn West trust units are listed on the New York Stock Exchange under the
symbol PWE.
