TECHNICALLY RECOVERABLE RESOURCES IN CONTINUOUS-TYPE DEPOSITS
Major coal-bearing areas in the lower 48 States are shown in figure 8.
The in-place resources of coal-bed gas are determined by the product
of the coal tonnage and gas content. Although the in-place resources
are very large for this type of accumulation, the main concern is
recoverability. Figure 8 also shows the location of areas within which
potential additions to reserves of coal-bed gas were quantitatively
assessed for 39 plays. For this assessment, technically recoverable
resources of coal-bed gas for the lower 48 States are estimated to
range from 42.9 TCFG to 57.6 TCFG, with a mean estimate of 49.9 TCFG.
Estimates for individual provinces and regions are presented in table 5.
