The estimated year-end 2007 reserves included proved developed reserves of 323 billion cubic feet of natural gas equivalent (bcfe) and proved undeveloped reserves of 80bcfe, and the split between gas and oil reserves was 53% and 47%, respectively.

Stone estimates that average production for 2007 was 224 million cubic feet of natural gas equivalents per day (mmcfe/d) which exceeded the 211mmcfe/d produced in 2006. Excluding the volumes from the divested Rocky Mountain properties, 2007 production would have averaged approximately 205mmcfe/d, the company said.
