CALGARY, Sept. 13 /CNW/ - EnCana Corporation (TSX, NYSE: ECA) has reached
an agreement to sell all of its shares in subsidiaries which have oil and
pipeline interests in Ecuador to Andes Petroleum Company, a joint venture of
Chinese petroleum companies, for approximately US$1.42 billion cash. The sale
will have an effective date of July 1, 2005 and is expected to close before
year-end. It is subject to prior approval by the Government of Ecuador, normal
closing conditions and regulatory approvals.
"This planned sale marks essentially the final step in sharpening the
focus on our unparalleled portfolio of unconventional natural gas and oil
resources in North America. It is also about concentrating our efforts and
investment where we have clear competitive advantage. Since EnCana was formed
in early 2002, we have reached agreements to divest of more than $10 billion
in non-core assets. We are proud of what our Ecuador team has accomplished
since entering the country in 1999 - substantially expanding production while
setting new higher standards in protecting the sensitive rainforest
environment. EnCana has also sponsored numerous environmental, health and
sustainable farming initiatives aimed at helping local communities," said
Gwyn Morgan, EnCana's President & Chief Executive Officer.
The net book value of EnCana's investment in Ecuador is approximately
$1.4 billion. Proceeds from the sale are expected to be directed to debt
reduction and the continuation of EnCana's share purchase program pursuant to
EnCana's current Normal Course Issuer Bid.

Harrison Lovegrove & Co. Limited has advised EnCana on the entire
divestiture transaction. Merrill Lynch acted as a strategic financial advisor

EnCana Corporation
With an enterprise value of approximately US$50 billion, EnCana is one of
North America's leading natural gas producers, is among the largest holders of
gas and oil resource lands onshore North America and is a technical and cost
leader in the in-situ recovery of oilsands bitumen. EnCana delivers
predictable, reliable, profitable growth from its portfolio of long-life
resource plays situated in Canada and the United States. Contained in
unconventional reservoirs, resource plays are large contiguous accumulations
of hydrocarbons, located in thick or areally extensive deposits, that
typically have low geological and commercial development risk, low average
decline rates and very long producing lives. The application of technology to
unlock the huge resource potential of these plays typically results in
continuous increases in production and reserves and decreases in costs over
multiple decades of resource play life. EnCana common shares trade on the
Toronto and New York stock exchanges under the symbol ECA.

ADVISORY REGARDING RESERVES DATA AND OTHER OIL AND GAS INFORMATION -
EnCana's disclosure of reserves data and other oil and gas information is made
in reliance on an exemption granted to EnCana by Canadian securities
regulatory authorities which permits it to provide such disclosure in
accordance with U.S. disclosure requirements. The information provided by
EnCana may differ from the corresponding information prepared in accordance
with Canadian disclosure standards under National Instrument 51-101        
(NI 51-101). EnCana's reserves quantities represent net proved reserves
calculated using the standards contained in Regulation S-X of the U.S.
Securities and Exchange Commission. Further information about the differences
between the U.S. requirements and the NI 51-101 requirements is set forth
under the heading "Note Regarding Reserves Data and Other Oil and Gas
Information" in EnCana's Annual Information Form.
In this news release, certain crude oil and NGLs volumes have been
converted to cubic feet equivalent (cfe) on the basis of one barrel (bbl) to
six thousand cubic feet (Mcf). Also, certain natural gas volumes have been
converted to barrels of oil equivalent (BOE) on the same basis. BOE and cfe
may be misleading, particularly if used in isolation. A conversion ratio of
one bbl to six Mcf is based on an energy equivalency conversion method
primarily applicable at the burner tip and does not necessarily represent
value equivalency at the well head.
