Philip A. Freeman
Philip Freeman is an Operations Research Analyst with the USGS Geology, Energy & Minerals (GEM) Science Center in Reston, VA.
Philip obtained his B.S. in Engineering at Cornell University in 1986. He is an Operations Research Analyst at the Eastern Energy Resources Science Center in Reston, Virginia. His experience in resource assessment work spans oil and gas, coal, reserve growth, and carbon dioxide storage resources. He has worked on teams tasked to develop probabilistic resource assessment methodologies. His contributions to economic analysis includes developing business development models, constructing geographic analysis and estimating annual production functions. He has experience combining large datasets of well, reservoir and field data for physical characterization of rock and/or fluid properties and using GIS for analysis or presentation.

Geologic energy storage
Introduction As the United States transitions away from fossil fuels, its economy will rely on more renewable energy. Because current renewable energy sources sometimes produce variable power supplies, it is important to store energy for use when power supply drops below power demand. Battery storage is one method to store power. However, geologic (underground) energy storage may be able to retain
