In a launch despatched to Rigzone just lately, the U.S. Geological Survey (USGS) outlined that, in an evaluation of undiscovered gasoline and oil within the Bossier Formation alongside the Gulf Coast, it has calculated that there are technically recoverable sources of 343.5 trillion cubic toes of gasoline and three million barrels of oil within the area.
The gasoline sources are sufficient to provide america for greater than 10 years on the present fee of consumption, in response to the discharge, which highlighted that, since manufacturing started, the Bossier Formation has produced 3.8 trillion cubic toes of gasoline, “equal to almost six weeks of U.S. consumption on the record-high 2025 stage”.
“The USGS outlined an Higher Jurassic Cretaceous-Tertiary Composite Whole Petroleum System (TPS) encompassing oil and gasoline all through the Gulf Coast area,” the USGS acknowledged in its report titled Evaluation of Undiscovered Oil and Fuel Sources within the Bossier Formation Inside the Onshore United States and State Waters of the Gulf Coast Area.

“Fuel in shales of the Bossier Formation could also be primarily self- sourced however might also be augmented by gasoline from the underlying Smackover and Haynesville Formations,” the report added, noting that the Bossier Formation “is widespread within the subsurface of Texas, Arkansas, Louisiana, Mississippi, Alabama, and Florida”.
In its launch, the USGS famous that, since its final evaluation of undiscovered oil and gasoline sources within the Bossier, exploration drilling by the business “has revealed deep, extremely over-pressured shale formations”, a growth the USGS outlined warranted a brand new evaluation.
“New performs, such because the Bossier Western Shale Fuel Evaluation Unit, generally referred to by business as ‘Western Haynesville’, or ‘Waynesville’, present that drilling into deeper, higher-pressured reservoirs may end up in extra sources than beforehand thought,” the USGS mentioned within the launch.
USGS Director Ned Mamula acknowledged within the launch, “the U.S. economic system and our lifestyle rely upon vitality, and USGS oil and gasoline assessments level to sources that business hasn’t found but”.
“On this case, we have now assessed there are vital undiscovered sources within the Bossier Formation,” he added.
The USGS famous in its launch that the Gulf Coast “has lengthy been some of the ample sources of U.S. vitality”.
“The organic-rich shales of the Bossier Formation are produced from as much as 18,000 toes under the floor, at higher depths than different sources within the Gulf Coast,” it added.
In a launch posted on its web site again in January, the USGS revealed that, in an evaluation of undiscovered gasoline and oil within the Woodford and Barnett shales within the Permian Basin, it had calculated that there are technically recoverable sources of 28.3 trillion cubic toes of gasoline and 1.6 billion barrels of oil within the area.
“Since manufacturing started within the late Nineteen Nineties, the Woodford and Barnett shales have produced 26 million barrels of oil, equal to at some point’s U.S. consumption,” the USGS acknowledged in that launch.
“The Permian Basin has lengthy been some of the ample sources of U.S. vitality. The organic-rich shales of the Woodford and Barnett happen as much as 20,000 toes under the floor, at higher depths than different sources within the Permian,” it added.
“Advances in unconventional manufacturing – hydraulic fracturing and horizontal drilling – now make it potential to supply vitality sources from beforehand inaccessible and technically difficult formations, such because the Woodford and Barnett,” it continued.
In its releases, the USGS highlighted that USGS oil and gasoline assessments started 50 years in the past “following an oil embargo towards the U.S. that signaled a necessity to grasp the incidence, distribution and potential volumes of undiscovered sources”.
The embargo led to a mandate for the USGS to make use of geologic science and information to evaluate undiscovered oil and gasoline sources to assist meet the nation’s wants, the USGS acknowledged within the releases, including that this work continues immediately, “figuring out new sources for home manufacturing in addition to worldwide sources that have an effect on market situations, an necessary a part of the USGS mission to offer actionable perception to U.S. leaders, different Federal businesses, business and the general public”.
In a press release despatched to Rigzone in December final 12 months, Mamula mentioned there are “vital” undiscovered sources within the Gulf Coast’s Haynesville Formation.
“The U.S. economic system and our lifestyle rely upon vitality, and USGS oil and gasoline assessments level to sources that business hasn’t found but,” Mamula famous in that assertion.
“On this case, we have now assessed there are vital undiscovered sources within the Haynesville Formation of the Gulf Coast,” he added.
A reality sheet posted on the USGS web site in December acknowledged that, “utilizing a geology-based evaluation methodology”, the USGS “estimated undiscovered, technically recoverable imply sources of 152 million barrels of oil and 47.9 trillion cubic toes of gasoline in reservoirs of the Haynesville Formation throughout the onshore United States and State waters of the Gulf Coast Basin”.
