  A common measure of the long-term viability of U.S. domestic crude oil and natural gas as an energy source is the remaining technically recoverable resource (TRR). TRR estimates are a work in progress, changing as more production experience becomes available and as new technologies are applied to extract these resources.

Estimates of technically recoverable natural gas resources for continuous-type (unconventional) plays in coal beds on federal lands of the conterminous United States. [Robert A Crovelli; Vito F Nuccio; Geological Survey (U.S.)]. The USGS estimates that there may be to billion barrels of undiscovered, technically recoverable oil in the Bakken Formation (with a mean estimate of billion barrels). These are estimates of oil that has yet to be found, but if found, could be produced using currently available technology and industry practices.

As shown in Table 1, estimates in the updated report taken in conjunction with EIA’s own assessment of resources within the United States indicate technically recoverable resources of  billion barrels of world shale oil resources and 7, trillion cubic feet of world shale gas resources. The Bakken Petroleum System: An Example Of A Continuous Petroleum Accumulation By Stephan H. Nordeng Introduction Recent assessments of the technically recoverable oil in the Bakken Formation point to a significant undeveloped resource within the Williston Basin. Even though the presence of oil in the Bakken has been known since the.   The calc. estimates of undis. recoverable resources are derived from natural gas estimates by applying historical NGL Natural Gas ratios. These figs. suggest that if added to crude oil estimates, natural gas liquids would increase the estimates of petroleum liquids by approx. 20%. (from Miller et al., ). An example of the expected growth in the U.S. unconventional gas resource base is shown in Fig. 7 and Table VII. Figure 7 shows the expected growth in tight gas sands, gas shales, and coalbed methane resource between the years and , stemming from an assumed continually improving knowledge base and technology. Table VII provides an update to Fig. 7, using the latest information .
