northern and central Appalachian basin, Cahaba coal field, Black Warrior Basin (Alabama)
- Figure l. Map of part of southwestern Virginia
showing coalbed methane fields in the central Appalachian basin. After Nolde (1995) and
Cardwell and Avary (1982).
- Figure 2. Map of northern West Virginia
and southwestern Pennsylvania showing coalbed methane fields and pools in the northern
Appalachian basin. After Bruner et al. (1995).
- Figure 3. Stratigraphy of coalbed methane beds
(bold) in the central and northern Appalachian basin. Scale, thickness and correlations of
beds and units in the central and northern Appalachian basin are not implied. Other
selected coal beds (not bold) are shown for stratigraphic reference.
- Figure 4. Number of new coalbed methane wells in
production in Virginia.
- Figure 5. Annual coalbed methane
production in Virginia (Bcf). Data from Nolde (1995); Jack Nolde, Virginia Division of
Mineral Resources, personal commun., April, 1996.
- Figure 6. Annual production (estimate) of
coalbed methane in central and northern Appalachian basin. This report.
- Figure 7. Comparison of coalbed methane
production in the central and northern Appalachian basin with that of the Black Warrior
basin. Note that the Black Warrior basin has reached production maturity, and the central
and northern Appalachian basin began significant production on 1992 and, therefore, is a
frontier area for coalbed methane development.

the Appalachian region (map modified from Rogers, 1994; data from Rice, 1995).
