EnCana closes sale of conventional natural gas assets

Sale generates approximately US$219 million in proceeds

CALGARY, Alberta (August 16, 2004) - EnCana Corporation (TSX, NYSE: ECA) has closed the previously announced sale of its conventional natural gas assets producing approximately 7,250 barrels of oil equivalent per day, after royalties, to a Calgary-based oil and gas producer for approximately US$219 million, which is subject to adjustments. EnCana plans to use the sale proceeds for general corporate purposes, including debt repayment.

EnCana Corporation
With an enterprise value of approximately US$30 billion, EnCana is one of the world's leading independent oil and gas companies and North America's largest independent natural gas producer and gas storage operator. Ninety percent of the company's assets are located in North America. EnCana is the largest producer and landholder in Western Canada and is a key player in Canada's emerging offshore East Coast basins. Through its U.S. subsidiaries, EnCana is one of the largest gas explorers and producers in the Rocky Mountain states and has a strong position in the deep water Gulf of Mexico. International subsidiaries operate two key high potential international growth regions: Ecuador, where it is the largest private sector oil producer, and the U.K., where it is the operator of a large oil discovery. EnCana and its subsidiaries also conduct high upside potential new ventures exploration in other parts of the world. EnCana is driven to be the industry's high performance benchmark in production cost, per-share growth and value creation for shareholders. 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.

Natural gas volumes that have been converted to barrels of oil equivalent (BOEs) have been converted on the basis of six thousand cubic feet (mcf) to one barrel (bbl). BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of six mcf to one bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent equivalency at the well head.

Natural gas volumes are sold based on heat content in British Thermal Units ("Btu's") but physically measured in standard cubic feet ("scf"). The heat content of natural gas varies by formation and therefore by production region. For example, the heat content of EnCana's natural gas production in Alberta is approximately 1,020 Btu/scf and the U.S. Rockies is approximately 1,110 Btu/scf. The average heat content of EnCana's natural gas production in total is approximately 1,040 Btu/scf or 1.04 million British Thermal Units ("MMBtu")/Mcf.

EnCana Corporation resource descriptions
EnCana uses the terms resource play, estimated ultimate recovery and resource potential. Resource play is a term used by EnCana to describe an accumulation of hydrocarbons known to exist over a large areal expanse and/or thick vertical section, which when compared to a conventional play, typically has a lower geological and/or commercial development risk and lower average decline rate. As used by EnCana, estimated ultimate recovery (EUR) has the meaning set out jointly by the Society of Petroleum Engineers and World Petroleum Congress in the year 2000, being those quantities of petroleum which are estimated, on a given date, to be potentially recoverable from an accumulation, plus those quantities already produced therefrom. Resource potential is a term used by EnCana to refer to the estimated quantities of hydrocarbons that may be added to proved reserves over a specified period of time largely from a specified resource play or plays. EnCana's current stated estimates of unbooked resource potential utilizes a five year time frame for their specified period of time.
