The widespread belief that shale gas plays will provide a cheap and abundant supply of natural gas while operators make a sizeable profit must be questioned based on results to date. Shale gas, like tight-sandstone gas, coal-bed methane and oil sands, is at the bottom of the resource pyramid and, therefore, while resource volumes are large, costs are high and recovery efficiency is low.
Based on several decades of experience with other low-permeability reservoirs, the expectation that shale gas plays will realize significantly higher profit margins seems unlikely and empirical results to date from longer-lived shale plays supports this observation.
Evaluation of the Barnett, Fayetteville and Haynesville shale plays suggests that company claims of reserves are over-stated by as much as 100 percent. This is largely because low decline-rate hyperbolic models are not supported by empirical production history data. Relatively long-lived production histories in the Barnett and Fayetteville shale plays suggest weakly hyperbolic decline matches with b-exponents that generally average less than 0.5 and rarely exceed 0.75.
Operator claims of profitability at less than $5.00 per thousand cubic feet of gas, therefore, must be questioned. These forecasts are based largely on point-forward economics and are at odds with costs reported to the Securities and Exchange Commission in 10-K filings. In fact, less than 10 percent of Barnett Shale wells have recovered break-even costs after eight years of horizontal drilling and modern fracture stimulation.
