NPGS Monthly Dinner Meeting—Thursday, Sept 5

Speaker: Dave Browning, TerraCore
Topic: Hyperspectral Core Imaging: Applications in Unravelling Deposit and Reservoir Mineralogy

Abstract: Hyperspectral core imaging is a passive and non-destructive spectroscopic method for identifying and mapping mineralogy in drill-cores and cuttings. Hyperspectral data is available across the Visible-Near-Infrared (VNIR; 350-1000nm), Short-Wave Infrared (SWIR; 1000-2500nm), and Long-Wave Infrared (LWIR; 7500-12000nm) regions. The information obtained allows for representative quantification of mineralogy across intervals, providing a reliable, consistent and objective record that is directly applicable to reservoir characterization. Hyperspectral core imaging also allows for the observation of mineralogical and textural properties which are not visually detectable, such as chemistry changes and grain size detection (i.e. sediment vs. cement). The rich dataset provided by hyperspectral imaging provides insight into conventional and unconventional resources, aiding the geologists in the understanding of their reservoir. The spectral data is collected by utilizing a core imaging workstation that combines a long-wave infrared (LWIR) hyperspectral camera with a SWIR hyperspectral camera and a high resolution RGB line scan camera. Several case studies will be presented demonstrating the importance of hyperspectral core imaging for petroleum and geothermal applications and how it can be utilized in conjunction with other datasets to better understand deposit and reservoir mineralogy.

Bio: Dave Browning has worked with hyperspectral data sets for over ten years, starting with utilizing spectroscopy as an exploration tool in Northeastern Nevada. He received a Master of Science degree from the University of Idaho, Moscow, for his thesis focused on ammonium bearing minerals and their ability to aid in regional exploration campaigns. As an exploration geologist he has designed and led several exploration campaigns focused in Nevada. Since joining TerraCore in 2014 he has been a lead geologist on projects of varying deposit types and industries across North America, from exploration through to production.
