USGS estimated mean Bossier resources at 108.6 tcf of gas, 2.9 billion bbl of oil, and 1 billion bbl of NGL.
It estimated mean Haynesville resources at 195.8 tcf of gas, 1.1 billion bbl of oil, and 900 million bbl of NGL.
In a 2010 assessment of Jurassic and Cretaceous potential on the Gulf Coast, USGS estimated gas resources at 9 tcf in the Bossier and 61.4 tcf in the Haynesville.
“Since the 2010 assessment, we’ve gotten updated geologic maps, expanded production history, and have a greater understanding of how these reservoirs evolved,” said USGS scientist Stan Paxton, author of the assessment. “All of that leads to a better geological model and therefore a more robust assessment.”
