In East Texas, the company recently completed its first operated horizontal Cotton Valley well (NRI –39 %). The 3,700 foot lateral well achieved an initial 24 hour gross daily production rate of approximately 7,100 Mcf of gas and 510 barrels of natural gas liquids. In addition, the company's first Chevron-operated horizontal Cotton Valley well (NRI - 39%) was recently completed and achieved an initial 24 hour gross daily rate of approximately 1,200 Mcf of gas and 95 barrels of natural gas liquids. The operator encountered mechanical problems during the completion, and as a result, only six of the frac stages were successfully performed on this short lateral (1,936 foot).

The company's third Classic operated horizontal Cotton Valley well (WI - 30%) has reached total depth and the company's fourth Classic operated horizontal Cotton Valley well (WI - 30%) is nearing total depth. Both Classic operated wells are expected to be completed during the third quarter. The company currently has three rigs (1 PQ – 1 Chevron – 1 Classic) working in the Southern portion of its Carthage field.

In the Niobrara, the company's first SM Energy Company-operated well (NRI -10%) was recently completed and achieved an initial 24 hour gross daily production rate of 837 barrels of oil. In addition, the company's fifth, fourth and third LoneStar operated wells, the McFarland (NRI – 15%), Davis (NRI - 20%) and Hester (NRI - 20%), were recently completed and achieved an initial 24 hour gross daily production rates of 1,605 barrels of oil, 211 barrels of oil and 201 barrels of oil, respectively. At this time, the company has concluded the first phase of its Niobrara drilling program. The company's five producing Niobrara wells drilled to date will be evaluated during the next six months before commencement of additional activity.

In South Texas, the company's first operated Eagle Ford Shale well (NRI - 37%) located in Dimmit County was recently completed and achieved an initial 24 hour gross daily production rate of 253 barrels of oil. The well has experienced erratic flowback, and the company continues to try to maximize the daily rates through optimization of artificial lift. In addition, the company's second operated Eagle Ford Shale well located in La Salle County has reached total depth and is currently being completed. The company's third operated Eagle Ford Shale well located in La Salle County has reached total depth and is expected to be completed during the fourth quarter.
