Approach Resources Inc. Reports Temporary Curtailment of Production Due to Third-Party Facility Power Failure

Approach Resources Inc. (NASDAQ: AREX) (“Approach” or the “Company”) today reported that its production has been curtailed due to a power outage at the Phillips 66 Sweeny, Texas refinery. The Company’s NGLs currently flow to the Sweeny refinery and fractionation complex through DCP Midstream’s processing plants in the Ozona, Texas area and through Chevron Pipe Line Company’s EZ Pipeline.

Power has been restored to affected fractionation units at the Sweeny complex. We estimate that production of approximately 5.2 MBoe/d has been curtailed since May 11, 2013, due to downtime caused by the power outage, and we expect a full return to service by the end of this week. Before the curtailment, the Company’s production for second quarter 2013 was averaging approximately 9.7 MBoe/d. As a result of the curtailment, the Company expects second quarter 2013 production to range from 8.7 MBoe/d to 9.1 MBoe/d, compared to prior guidance of 9.3 MBoe/d to 9.6 MBoe/d.

DCP Midstream’s Sand Hills pipeline is expected to begin providing market access for NGLs from the Permian Basin to Mont Belvieu by the end of second quarter 2013. As noted above, the Company currently sells its natural gas and NGLs to DCP Midstream. The Company expects that DCP’s Sand Hills pipeline will improve the reliability of the Permian to Gulf Coast NGL network and mitigate future curtailments by providing additional takeaway capacity from the region.

Approach Resources Inc. is an independent oil and gas company with core operations, production and reserves located in the Permian Basin in West Texas. The Company targets multiple oil and liquids-rich formations in the Permian Basin, where the Company operates approximately 148,000 net acres.
