Shale Gas and Hydraulic Fracturing: CRS Experts 
 
he use of hydraulic fracturing—along with advanced drilling methods—has enabled the 
production of oil and gas from unconventional (low-permeability) reservoirs that were 
T previously inaccessible. This technique is now used on more than 90% of new wells and 
has resulted in the marked expansion of estimated U.S. oil and natural gas reserves in recent 
years.1 The rapidly expanding use of hydraulic fracturing has drawn congressional attention to a 
range of related issues including potential environmental impacts; state and federal regulatory 
requirements; implications for domestic oil and gas supplies and energy independence; pipeline 
capacity and development; and others. The following tables provide names and contact 
information for CRS experts on major issues associated with hydraulic fracturing and 
unconventional oil and gas resource development. (See also CRS Report R42667, Oil, Natural 
Gas, and Coal: CRS Experts, by Michael Ratner and Brent D. Yacobucci.)

1 Hydraulic fracturing is done after a well is drilled and involves injecting large volumes of water, sand (or other 
propping agent), and specialized chemicals under enough pressure to fracture the formations holding the oil or gas. The 
sand or other proppant holds the fractures open to allow the oil or gas to flow freely out of the formation and into a 
production well. See CRS Report R42333, Marcellus Shale Gas: Development Potential and Water Management 
Issues and Laws, by Mary Tiemann et al., and CRS Report R42032, The Bakken Formation: Leading Unconventional 
Oil Development, by Michael Ratner et al.
