Dune Energy has commenced drilling the State Lease 214 #912 well at its Garden Island Bay Field, located in Plaquemines Parish, Louisiana. The well, the initial follow up to Dune's very successful 2007 drilling program, is scheduled to reach total depth of 9,300 feet by mid-August, with production anticipated in September. Garden Island Bay has been producing approximately 1,500 B/d of oil plus 1.5 MMcf/d of natural gas. The #912 is expected to add 4 MMcf/d of natural gas and 250 B/d of oil. Several low-risk development wells have also been identified for drilling later in 2008 and into 2009. These wells will be scheduled to coincide with an upgrade of the field's gas lift system. Other Field Operations

At the Company's Leeville Field in Lafourche Parish, LA, 4 wells are scheduled to be sidetracked for newly recognized updip potential, and a deep well (12,500 feet) targeting the Cib Carst sands is planned. All of these wells are being drilled by a private entity, with Dune maintaining a 20% carried interest. In the deep well, Dune will maintain an overriding royalty interest with an option to convert to a working interest at payout. Dune's net production in the field has averaged 300 Mcf/d of natural gas and 220 B/d of oil. This drilling activity is anticipated to contribute an incremental net 200-300 B/d of oil and 100 - 200 Mcf/d of natural gas. At the Comite Field, in Baton Rouge Parish, LA, Dune is currently conducting a workover of the Cobb #1 well in an effort to eliminate water production from a zone below the primary reservoir. Success on this Tuscaloosa project is anticipated to add 1 - 3 MMcf /d of natural gas in additional net production. Dune has a 100% working interest in this well.

In the Chocolate Bayou Field, in Brazoria County, TX, Dune anticipates offsetting the highly successful Wieting #30 well, completed during the first quarter, with the Wieting #31 during the fourth quarter. Dune will retain an approximate 50% working interest in this well, which will test the IP Farms zone updip of what was encountered in the #30 well, plus several prospective shallow sands. The Wieting #30, in which Dune holds a 100% working interest, is currently producing approximately 4 MMcf/d of natural gas and 450 B/d of oil. Dune anticipates similar volumes from the Wieting #31.

At the Bayou Couba Field, in St. Charles Parish, LA, the Company, along with its major integrated partner, is completing its review of a newly reprocessed 3-D seismic data set. Dune anticipates a 13,400-foot exploratory test for drilling later in the year. Dune expects to maintain between a 25 - 50% working interest in this high impact project. The Company will also participate in two additional exploratory wells, which will be completed during the second half of 2008.

Dune has a 23% working interest in a non-operated 10,900 foot Frio sand test at Alvin Townsite, in Brazoria County, TX, which the Company anticipates to be drilled in the third quarter. In addition, Dune has a 30% non-operated working interest in the continuation of the Delaware Deep project located in Sweetwater County, Wyoming. This well will be deepened approximately 400 feet to test the Almond Channel sand, and a completion will then be attempted in that zone or one of the shallower zones penetrated last year prior to suspension of operations due to winter weather.
