Co-Principal Investigator: Nuclear Forensics: DNO Analyses for Quantitative Mineral Identification. 2015-2018
Forensic signatures for identifying processing history in nuclear forensics
Research related to the morphological changes that take place during the processing and storage of uranium oxides providing valuable information on the processing history and storage conditions of potentially interdicted samples. Modeling of the crystallographic changes in UO2 and α-U3O8related to varying environmental conditions e.g. elevated temperatures in controlled oxygen environments. Forensics signatures derived from this work are used to identify, compare, and contrast the processing history in relation to other sample signatures e.g. interdicted material.
TENORM elemental assessment of shales related to hydrocarbon production
Assessment of shale formations for TENORMS (Technologically Enhanced Naturally Occurring Radioactive Materials) produced via hydraulic fracturing. Research investigates the elemental composition of shale formations at the bulk and microstructural scale to better understand the relationship between major naturally occurring radioactive elements (NORM) and organic phases within shales. Both XRD and QEMSCANÒ were used to identify non-crystalline phases and provide spatial mapping of the minerals through the shale samples. In addition, XRD and QEMSCAN were used to determine the total sulfur and carbonate content as this greatly contributes to the acidity of the shale and subsequently, U and Th migration. Select samples were characterized by scanning electron microscopy – energy dispersive x-ray spectroscopy (SEM/EDX) to reveal the presence of heavy metals (i.e. U, Pb) near hydrocarbon-rich regions of the shale. The NORM content and organic content were also correlated using gamma well logging.
Co-Principal Investigator: A Searchable Index and Analytics Engine for USGS and State Core Databases 2013-2016
Optimization of oil and gas exploration data using visualization architecture
Development of visualization architecture that foregoes the ETL (exact, transform, load) process allowing quick access to multiple data sources. The architecture uses an indexing engine for accessing data with multiple schema with a series of small data analysis microservices adding intelligence to the architecture. Visualizations are designed to display and explore the data itself, as well as the structure of the data, facilitating discovery. This combination of features enables rapid prototyping of visualizations for a variety of data types, formats, and schema.
