POTENTIAL BASIN-CENTERED GAS ACCUMULATIONS WITH RESPECT TO USGS 1995
PETROLEUM ASSESSMENT
This section briefly describes how the 33 accumulations identified for this study relate to the USGS 1995
assessment. The reason we chose several of the accumulations for this study is that they were not either identified,
assessed, or understood well in 1995. However, at the present time, we feel that all 33 have at least some potential
for new gas resources. Shown, is the name of the accumulation, the Region of the U.S. where it is located (as
defined in the 1995 assessment), the Province where the accumulation is located (as defined in the 1995 assessment),
and a note about how the accumulation relates to the plays identified and assessed for that Province in 1995.
Accumulation
Region
Province
Notes
Sacramento Basin 2 9 2 conventional plays assessed. No
continuous plays assessed; potential for
new gas resources.
San Joaquin Basin 2 10 No continuous plays assessed; potential
for new resources in Late Cretaceous
strata.
Raton Basin 4 41 No continuous plays assessed; potential
in L. Tertiary and U. Cretaceous strata.
Rio Grande Rift 3 23 5 conventional plays assessed. No
continuous plays assessed.
Anadarko Basin 7 58 5 conventional plays assessed. 1
continuous play defined but not assessed.
Potential for new continuous gas in
Miss. and Penn. Strata.
Travis Peak/Cotton Valley 6 49 2 conventional and 1 continuous Cotton
Valley play assessed. Need to re-evaluate
conventional to see if it is actually
continuous.
Columbia Basin/ 2 4 1 continuous play assessed. Need W.
Flank of Cascades for further study based
on new perceptions.
Michigan Basin/St. Peter Ss 8 63 2 unconventional shale plays assessed.
No continuous Ss plays assessed but
potential new gas may be identified in
Ss.
Cook Inlet, Alaska 1 3 3 conventional plays assessed. No
Continuous plays identified or assessed.
Potential in Cretaceous and Jurassic
strata.
Permian Basin/Abo Formation 5 44 No continuous plays assessed. Potential
in Abo Fm.
