Mr. Roberts has 35 years of experience in hydrogeologic testing and data analysis related to the characterization of complex flow systems such as low-permeability, fractured, and heterogeneous systems. Mr. Roberts was the well-test analysis lead at the U.S. Department of Energy’s Waste Isolation Pilot Plant (WIPP) for 17 years where he was involved in a variety of tests including pulse, slug, constant pressure, hydro- fracturing, and constant-rate tests. He was the technical lead for the design of the numerical well-test analysis code, nSIGHTS, and is the world’s leading authority on the application of nSIGHTS. Mr. Roberts worked with experts from multiple disciplines to develop an advanced methodology for quantifying uncertainty in hydraulic parameters estimated via the well-test analysis process. This same methodology can be used to design field-testing programs, ensuring the most cost-efficient data collection needed to meet defined project objectives. He has worked extensively in the area of site characterization associated with nuclear waste repository programs in the United States, Canada, Switzerland, France, Japan, Sweden, Germany, Taiwan, and Korea, performing and interpreting hydraulic tests and providing training in advanced well-test analysis. Mr. Roberts has participated in both deep borehole testing and tests in underground facilitiesIn addition to his hydrogeologic skill set, Mr. Roberts is also a photographer/astrophotographer and is learning to play the Irish tin whistle. The whistling is improving...
