Bakken Shale - Encore EAC - Sanish Well Results

Today Encore Aquisition Company ( EAC ) has updated its investors on their Bakken Shale Play.

EAC today reported initial results from its first well drilled in the Sanish Formation of the Bakken Shale Trend.

Encore recently finished drilling and completing its first well in the Sanish Formation of the Bakken Shale Trend, the Charlson 11-16H, in Williams County, North Dakota. The well was brought online on July 23 at an initial production rate of 1,106 BOE per day flowing up 7" casing. The Company has a 96 percent working interest in the well, which also contains very favorable pay in the Bakken Formation. The well is approximately four miles northwest of the best Sanish well drilled to date in North Dakota, the USA 2D-3-1H, which has produced over 560,000 BOE in 19 months.

Encore owns 10,400 net acres in the Charlson area and can drill or participate in an additional 28 wells on its current acreage position in this area of the Sanish. The Company is currently drilling a second Sanish well in the Charlson Field, which it plans to complete in the third quarter. Encore plans to drill a total of six wells in the Sanish in the Charlson Field in 2008. Additionally, two other Sanish wells will be drilled in the Charlson area offsetting the USA 2D-3-1H well. This area is prospective for both the Sanish and Bakken Formations, which could significantly add to the total recoverable reserves under the Company's leases.

As previously disclosed, Encore has recently expanded its acreage position in the Bakken and Sanish Shale Play to over 240,000 net acres. Encore plans to add a third rig to drill Bakken and Sanish wells in August 2008. Upon arrival of the additional rig, Encore plans to drill a Sanish well in its Cherry Creek Prospect, where the Company owns a significant lease position of approximately 70,000 net acres. Encore believes its Cherry Creek Prospect is in the Sanish fairway. The Company also plans to commence drilling in August in the Company's Almond Prospect, in Mountrail and Ward Counties, North Dakota, in which the Company currently holds an acreage position of approximately 53,000 net acres. The Almond Prospect is prospective for both the Sanish and Bakken Formations. The Company expects to drill and complete five-to-six Bakken and Sanish wells in the third quarter of 2008, as well as re-frac several current Bakken producers.
