Gastar Begins Initial Production from its East Texas Gas Pla

Gastar Exploration has commenced initial production from the Gastar Fridkin-Kaufman Ltd #1 ("Gastar F-K #1") well in the Hilltop area of East Texas. Gastar has a 77.5% working interest in the well through its wholly-owned subsidiary First Texas Development, Inc.

The Gastar F-K #1 well has commenced production at an initial gross stabilized rate of 15 MMCFD (8.5 MMCFD net to Gastar) with over 10,000 psi flowing tubing pressure. The well's current production rate is restricted by the gas processing capacity currently available. The well is producing from three separate zones in the Deep Bossier formation.

Gastar's President and CEO, J. Russell Porter, commenting on the announcement, said, "The Gastar F-K well is one of the better natural gas wells reported in East Texas in recent memory and is further confirmation of the fact that Gastar and its partners have made a significant deep natural gas discovery. We are about to commence completion operations on our second Deep Bossier well, the Cheney #1 well, and we are currently drilling another well targeting the Upper and Middle Bossier formations, the Lone Oak Ranch #1 well. Gastar has a substantial interest in over 30,000 gross acres and is planning to continue drilling operations to both develop this discovery and explore the aerial extent of the discovery. We are also acquiring and proprietarily re-processing additional seismic data in order to refine our future drilling plans."

Gastar Exploration, Ltd. is an exploration and production company focused on finding and developing natural gas assets in North America and Australia.
