This course is held online over 2 days on the following schedule (All times in Eastern Time Zone):

10 am to 6 pm Eastern (Will include the usual breaks)

After participating in this course, you will be able to:

  • Visualize subsurface materials and associated investigations: Understand and interpret subsurface data and materials.
  • Utilize information such as drill hole databases and mapping more efficiently: Efficiently use drill hole data and mapping for better project insights.
  • Design and use geophysical surveys and drilling: Plan and implement effective geophysical surveys and drilling operations.
  • Oversee inference of strata, structures, and properties: Supervise the interpretation of subsurface strata, structures, and material properties.
  • Support activities such as groundwater modelling and subsurface installations: Aid in groundwater modeling and the installation of subsurface infrastructure.

This course is on accounting for geological materials that host underground structures, foundations, waste disposal, groundwater, geothermal, fossil fuels, mineral resources, and geological research.

Topics will include survey design, data compilation such as drill hole databases, data acquisition such as geophysical surveys, inference of strata and structures, specification of properties, heterogeneity, and uncertainty for sediments and rocks, as well as applications to energy, mineral, and water resources, engineering, waste disposal, and research.

  • Underground structures
  • foundations
  • slope stability
  • groundwater
  • oil and gas
  • geothermal
