Many of the independents on the fourth-quarter Oil and Gas Investor This Week scoreboard reported healthy gains in production, compared with the same period last year, from a mixed bag of acquisition and exploration efforts. Most also reported increases in their year-end proved reserves, while the cost of growth via the drillbit grew. JP Morgan analyst Joe Allman estimates proved developed reserve finding and development costs rose from $2.11 per thousand cubic feet equivalent in 2005 to about $3.81 in 2006. "Our analysis suggests that the E&Ps as a whole are struggling to return their cost of capital in the current environment," Allman says. "To earn adequate returns-at least a 20% pre-tax rate of return-the average E&P requires $8-plus gas prices and/or lower costs. We expect costs to decrease because of excess onshore rig and pressure-pumping capacity, and drilling activity to slow if gas futures go below $7." The names in the year-over-year production-growth winners' circle include Petrohawk Energy Corp., Anadarko Petroleum Corp., Stone Energy Corp., Newfield Exploration Co. and Ultra Petroleum Corp.
