Comparison of Publicly Available Methodologies for Development of Geologic Storage Estimates for Carbon Dioxide in Saline Formations

September 4, 2013
Author(s)
Angela Goodman, Grant Bromhal, Brian Strazisar, Traci Rodosta, William F. Guthrie, Doug Allen, George Guthrie
Carbon dioxide storage resource estimates are compared by applying several commonly used methods to general saline formation data sets to assess the impact that the choice of method has on the results. Methods applied include those by 1) ministerial-level

Comparison of Publicly Available Methodologies for Development of Geologic Storage Estimates for Carbon Dioxide in Saline Formations

February 1, 2013
Author(s)
Angela L. Goodman, Grant Bromhal, Brian Strazisar, Traci Rodosta, William F. Guthrie, George Guthrie
High-level estimates of CO2 storage resource for application to saline formations at the national, regional, and basin scale are required to assess the potential for carbon capture, utilization, and storage technologies to reduce CO2 emissions. Both

Certification of SRM 2492: Bingham Paste Mixture for Rheological Measurements

June 7, 2012
Author(s)
Chiara F. Ferraris, Paul E. Stutzman, William F. Guthrie
Rheological measurements are often performed using a rotational rheometer. In this type of rheometer, the tested fluid is sheared between two surfaces, one of which is rotating [1]. Usually, the angular velocity is imposed and the response of the material

Performance of New and Aged Residential Fire Sprinklers

August 31, 2011
Author(s)
Anthony D. Putorti Jr., William F. Guthrie, Jason D. Averill, Richard G. Gann
The U.S. Consumer Product Safety Commission (CPSC) initiated a program to determine the effects of emissions from problem drywall on residential electrical, gas distribution, and fire safety components. As part of this program, the National Institute of

Origin and Early History of Die Methode des Eichzusatzes or The Method of Standard Addition with Primary Emphasis on Its Origin, Early Design, Dissemination, and Usage of Terms

June 1, 2011
Author(s)
William R. Kelly, Kenneth W. Pratt, William F. Guthrie, Keith R. Martin
The Method of Standard Additions or the Standard Addition Method, often referred by its acronym as just SAM, is now a proverbial workhorse in both inorganic and organic quantitative analytical chemistry and in related disciplines such as geochemistry. Its
