Energy Resources Program


The Energy Resources Program conducts research and assessments to advance the understanding of the Nation’s energy resources. We study processes critical to the formation, accumulation, occurrence and alteration of geologically based energy resources; prepare resource assessments; and evaluate the environmental and socioeconomic effects of energy resource occurrence, production and use.

Assessment of undiscovered gas resources of the Sacramento Basin Province in California, 2019

Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean resources of 512 billion cubic feet of gas in the Upper Jurassic–Neogene Total Petroleum System of the Sacramento Basin Province in California.

Exploring methane behavior in marcellus shale micropores via contrast matching neutron scattering

Petroleum in shale reservoirs is hosted in organic matter and mineral pores as well as in natural fractures and voids. For thermally mature plays, e.g., the Marcellus Shale, methane and other light alkane gases are thought to be primarily contained in organic matter pores with radii ≦50 nm. Thus, in order to understand natural gas occurrence,...

Repetitive sampling and control threshold improve 16S rRNA results from produced waters associated with hydraulically fractured shales

Sequencing microbial DNA from deep subsurface environments is complicated by a number of issues ranging from contamination to non-reproducible results. Many samples obtained from these environments - which are of great interest due to the potential to stimulate microbial methane generation - contain low biomass. Therefore, samples from these...
