Geology, Energy & Minerals (GEM) Science Center

Comprehensive, Interdisciplinary Research and Surveys

Geology, Energy & Minerals Science Center

Scientists within the GEMSC represent a breadth of programs focused on the USGS mission; Energy Resources Program, Mineral Resources Program, National Cooperative Geologic Mapping Program, and Environmental Health Programs. GEMSC conducts comprehensive, interdisciplinary research and surveys of the origin, occurrence, distribution, quantity, and composition of oil, gas, coal, minerals, and more.

What We Provide

GEMSC conducts comprehensive, interdisciplinary research and surveys of the origin, occurrence, distribution, quantity, and composition of oil, gas, coal, minerals, and associated deposits. We provide up-to-date, publicly available, scientific data.

What We Address

GEMSC was established in 2020 through the merger of the Eastern Energy Resources and the Eastern Mineral and Environmental Resources Science Centers. Our work is broadly applicable to current and emerging geology, energy, and minerals issues.

A probabilistic assessment methodology for the evaluation of geologic energy storage capacity—Natural gas storage in depleted hydrocarbon reservoirs A probabilistic assessment methodology for the evaluation of geologic energy storage capacity—Natural gas storage in depleted hydrocarbon reservoirs

The need for energy storage, particularly underground, where capacity and duration may far exceed battery storage technologies, is especially relevant given the increasing demands for reliable power alongside the development of intermittent renewable electricity sources. Geologic energy storage facilities already exist, and expanded use would enable storing gases such as methane and...

Regional characterization of coal resources in the U.S. Gulf Coast Regional characterization of coal resources in the U.S. Gulf Coast

There is increasing interest in extracting critical minerals (CM), including rare earth elements (REE), from coals in the United States to address the overreliance on imported REE. The U.S. Gulf Coast and the Williston basins are the two major lignite-bearing basins within the country. Recent REE and CM studies of the lignite in these basins have indicated that the coals may be a viable...

Review and synthesis of the applications of machine learning to coalbed methane recovery Review and synthesis of the applications of machine learning to coalbed methane recovery

Over the last 30 years, a substantial literature has evolved on the use of machine learning (ML) to assess, predict, and improve the efficiency of coalbed methane (CBM) recovery. In the United States, the production of CBM declined as shale gas production matured, but CBM continues to be an important energy resource in other parts of the world. ML applications that have the potential to...
