Conversion, bcm to tcf:
- 146 bcm = 5.1556 tcf (this number may vary slightly from site to site)
From The Oil & Gas Journal, December 17, 2021:
USGS reports that Williston basin’s Bakken and Three Forks formations within Montana and North Dakota include 4.3 billion bbl of unconventional oil and 4.9 tcf of unconventional natural gas, both reduced from its 2013 assessment.
The US Geological Survey (USGS) reports that Williston basin’s Bakken and Three Forks formations within Montana and North Dakota include 4.3 billion bbl of unconventional oil and 4.9 tcf of unconventional natural gas.
This assessment is for undiscovered, technically recoverable resources and updates a 2013 USGS assessment of Williston basin which found that undiscovered reserves totaled 7.4 billion bbl for Bakken and 6.7 tcf for Three Forks.
Since the 2013 assessment, more than 6,400 additional wells have been drilled in the Bakken formation, and about 4,100 wells have been drilled in the underlying Three Forks formation, resulting in both more production and more knowledge of the basin’s resources.
To date, more than 17,500 total wells have been drilled into Bakken and Three Forks formations, and about 4 billion bbl oil have been produced from these units.
The Bakken boom began in Montana in 2000 and in North Dakota in 2007.
