Known source and reservoir rocks extend throughout a thick sedimentary
section ranging from Pre-Cambrian to Tertiary in age. Virtually every conceivable
type of tectonic and sedimentary environment known is present in some area
of the Region.
Additional oil production from established plays is not expected to
be large. Largest potential exists in unconventional plays and in sparsely
drilled deeper sections of individual basins.
Gas will be more important than oil. Most of the gas potential is related
to sources in coal-bearing sections of the Cretaceous and Tertiary. Much
of this gas will be found in coal bed reservoirs or in low-permeability
sandstones. Oil-prone petroleum systems in deeper and less-explored parts
of many basins will contain gas because of advanced thermal maturity.
Much of the potential production will fall in the middle and lower ranges
of "Masters' Resource Triangle," which in the case of the Rocky Mountain
Region has a broader base than many other areas of the World. Exploration
and development will be greatly influenced by technical, economic and political
factors.
Examples of recent significant discoveries that may serve as analogs
for the future will be presented. Many of these "discoveries" are unconventional
accumulations and have resulted from the application of new technology
to areas of previously abandoned or non-/sub-commercial wells.
