Cimarex Energy Provides Update on Impact from Recent Hurricanes

DENVER, September 22, 2008 - Cimarex Energy Co. (NYSE: XEC) today provided an operations update on the impact from hurricanes Gustav and Ike.

Cimarex’s daily production prior to the storms had been averaging at the upper end of its previous third-quarter guidance of 485 - 495 million cubic feet equivalent per day (MMcfe/d). The storm impact is expected to reduce third-quarter average production by approximately 18 MMcfe/d. Third-quarter volumes are now expected to average between 475 - 480 MMcfe/d.

Prior to the storms Cimarex’s Gulf of Mexico production was approximately 17 MMcfe/d. This production is primarily non-operated. The operators of the blocks shut-in the producing wells prior to the storms and the majority of this production has been offline since the end of August. Initial reports from outside operators indicate one lost platform. Cimarex’s net production from the lost platform was less than 1 MMcfe/d. Otherwise damage appears to be minimal and is in the process of being repaired.

The Company’s onshore Gulf Coast properties also had minor storm damage. The storms have also impacted southern Oklahoma and certain Permian Basin liquid-rich gas production because of disruptions to third-party liquids handling.

Total onshore and offshore shut-in production peaked at 126 MMcfe/d on September 14, 2008. Current shut-in production is 70-75 MMcfe/d, with the onshore production expected to be back online before the end of September.
