EXHIBIT 99.1

Encore Acquisition Company Announces an Agreement with Kerr-McGee to Acquire
Producing Properties in West Texas and Oklahoma for $104 Million

FORT WORTH, Texas—(BUSINESS WIRE)—October 19, 2005

Encore Acquisition Company (NYSE:EAC) today announced that it has entered into an agreement with Kerr-McGee Corporation to purchase oil and gas properties in the Permian Basin in West Texas and the Anadarko Basin in Oklahoma for $104 million. The transaction is expected to close in November.

The properties are located in the Levelland-Slaughter, Howard Glasscock, Nolley-McFarland and Hutex fields in West Texas and the Oakdale, Calumet and Rush Springs fields in western Oklahoma. Encore’s internal engineers have estimated total proved reserves to be 6.2 million barrels of oil equivalent (“BOE”), which are 94% oil and 69% proved developed producing. The properties are long-lived with current production of approximately 1,300 BOE per day and a reserves-to-production ratio of 9 years. Lease operating costs are $13.73 per BOE. These fields are mature legacy waterfloods with large volumes of original oil in place.

Encore has identified 1.9 million barrels of proved undeveloped opportunities on these properties with total capital requirements of approximately $12 million. This capital targets reserves through infill drilling and down-spacing in existing fields.

The Company plans to finance this acquisition with internally generated cash flow and by drawing down its bank facility. Encore has entered into swaps for approximately 50% of the acquisition’s proved developed producing volumes with the following fixed prices: $62.09 for 2006, $60.84 for 2007, and $59.64 for the first half of 2008. Encore intends to swap the remaining proved developed producing volumes over the same time periods. In addition, on its entire base production, the Company has increased its portfolio of put options to approximately 80% of its projected 2006 volumes. This will mitigate the negative effects of any downward movement in the price of oil and gas, while retaining the benefits of increasing commodity prices.

About the Company:

Organized in 1998, Encore is a growing independent energy company engaged in the acquisition, development and exploitation of North American oil and natural gas reserves. Encore’s oil and natural gas reserves are in four core areas: the Cedar Creek Anticline of Montana and North Dakota; the Permian Basin of West Texas and Southeastern New Mexico; the Mid Continent area, which includes the Arkoma and Anadarko Basins of Oklahoma, the North Louisiana Salt Basin, the East Texas Basin and the Barnett Shale; and the Rocky Mountains. Encore’s latest investor presentation is available on the Company’s website at www.encoreacq.com.

Cautionary Statements:

This press release includes forward-looking statements, which give Encore’s current expectations or forecasts of future events based on currently available information. Forward-looking statements in this press release relate to, among other things, the following: estimates of proved reserves, current production and the reserve-to-production ratio; the ability to increase production; potential upsides; expected cash flows and capital requirements; the expected closing of the transaction; the anticipated funding of the acquisition; the level of lease operations expense; Encore’s expectations with respect to hedges; and any other statements that are not historical facts. The assumptions of management and the future performance of Encore are subject to a wide range of business risks and uncertainties and there is no assurance that these statements and projections will be met. Factors that could affect Encore’s business include, but are not limited to: the risks associated with operating in a limited number of geographic areas; the risks associated with drilling of oil and natural gas wells; risks related to Encore’s high-pressure air program; Encore’s ability to find, acquire, market, develop, and produce new properties; the risk of drilling dry holes; oil and natural gas price volatility; hedging arrangements (including the costs associated therewith); uncertainties in the estimation of proved, probable and potential reserves and in the projection of future rates of production and reserve growth; inaccuracies in Encore’s assumptions regarding items of income and expense; uncertainties in the timing of exploitation expenditures; operating hazards attendant to the oil and natural gas business; drilling and completion losses that are generally not recoverable from third parties or insurance; potential mechanical failure or underperformance of significant wells; climatic conditions; availability and cost of material and equipment; actions

or inactions of third-party operators of Encore’s properties; Encore’s ability to find and retain skilled personnel; diversion of management’s attention from existing operations while pursuing acquisitions or joint ventures; availability of capital; the strength and financial resources of Encore’s competitors; regulatory developments; environmental risks; general economic and business conditions; industry trends; and other factors detailed in Encore’s most recent Form 10-K and other filings with the Securities and Exchange Commission. If one or more of these risks or uncertainties materialize (or the consequences of such a development changes), or should underlying assumptions prove incorrect, actual outcomes may vary materially from those forecasted or expected. Encore undertakes no obligation to publicly update or revise any forward-looking statements.

The Securities and Exchange Commission permits oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. We use certain terms such as “potential”, “upside”, or other descriptions of volumes of reserves potentially recoverable through additional drilling or recovery techniques that the SEC’s guidelines would prohibit us from including in filings with the SEC. These estimates are by their nature more speculative than estimates of proved reserves and, accordingly, are subject to substantially greater risk of being actually realized by Encore. Investors are urged to consider closely the disclosure in our Form 10-K and Form 10-Qs, File No. 1-16295, available from us at Encore Acquisition Company, 777 Main Street, Suite 1400, Fort Worth, Texas 76102, Attention: Corporate Secretary. You can also obtain these forms on the SEC’s website at www.sec.gov.
