Business Impact: This course will provide critical understanding and hands-on skills for participants working in areas where shelf processes and deposits impact the design and maintenance of wind energy and communications emplacements or success in drilling exploration and development wells.

Through a combination of lectures and case studies, participants will be exposed to many of the aspects that influence design and maintenance of seafloor emplacements with emphasis on predicting, mapping, and quantifying substrate character and predicting variables that influence seafloor and sub-seafloor conditions. The lecture content provides a summary of the fundamentals of hazards analysis and hazards recognition in marine settings. Participants will gain hands-on experience in utilizing remotely sensed data (seismic, sonar, sub-bottom profiler data), logs and core/samples for interpretation of near seafloor structures and sediments, and discuss the recognition criteria for assessing hazards, as well as a background in the variables that influence hazards development in marine settings.

Duration and Training Method

A virtual classroom course divided into 4 webinar sessions (equivalent to a two-day classroom course), comprising lectures, discussion, case studies, quizzes, and practical exercises to be completed by participants during and between sessions.

Participants will learn how to:
  1. Interpret a variety of different types of data (i.e. seismic, core, samples, strength data, etc.) and integrate those data to derive the condition and state of shelves. 
  2. Translate depositional form into process, then process into sedimentology, and create a risk matrix to assess the implications to business objectives. 
  3. Differentiate tectonic structure from depositional architecture. 
  4. Apply the tools of observation, annotation, and interpretation of various scales of seascape morphology, including regional and localized features. 
  5. Define and justify critical criteria for assessing hazards in a shelf setting and translate those assessments to map exclusion zones. 
  6. Estimate risk, uncertainty, and bias in data interpretation, and utilize this knowledge to make decisions. 

The course is intended to generate instructive discussion among professionals, moderated and guided by the instructor. Exercises will be assigned each day to reinforce the lectures and class participants will complete exercises in class or overnight. Results will be reviewed by participants and the instructor in class.

The following indicates the planned content of the course.

1. Processes and deposits of the global oceans

  • Welcome and introduction
  • Background in seafloor physical processes and deposits
  • Architecture and structure of the shallow seafloor
  • Storm, wave, and tidal processes active in the oceans and their impact
  • Exercise: Predicting hazard processes from deposits
  • Tools and tool resolution for interpreting the sub-seafloor

2. Interpreting Seafloor Character

  • Interpreting the geomorphology of shallow submarine substrates
  • Interpreting shallow structure and sediments; hi-res seismic, sonar, sub-bottom profiler data
  • Exercise: Interpreting the geomorphology of the sea floor
  • Seafloor processes and sediment character
  • Exercise: Integrating borehole data with seismic

3. Hazards Recognition and Assessment

  • Forces acting on seafloor emplacements
  • Shallow gas and overpressure, mass transport deposits
  • Exercise: Interpreting hazards in sub-seafloor data
  • Exclusion Zones Map (EZM) construction
  • Exercise: Determining exclusion zone extents
  • Wrap-up

Who should attend

The course is aimed at geologists, geophysicists, engineers and managers involved in planning and constructing emplacements in shelf settings.

Prerequisites and linking courses

There are no formal prerequisites for this course. However, the online workshop format demands a high degree of participation and involvement from attendees. Computing skills in either Powerpoint, ArcGIS or Adobe Illustrator are required to interpret over digital images provided.

Lesli Wood

My technical expertise is in clastic sedimentology, sequence stratigraphy, and seismic geomorphology. I specialize in the study of land margins and the processes, deposits, and fluid systems that characterize them. This interest extends to systems on other planets, as well as on Earth. I have extensive experience in physical modeling of clastic processes and a strong interest in predictive models of complex geomorphic response to extrinsic and intrinsic changes.

In addition, I have research interests in gas hydrates, shale tectonics, and the biotic and fluid systems of deep-ocean mud volcanoes. My industry experience includes integrated study of petroleum systems, exploration prospect development and operations, and regional hydrocarbon prospect evaluation. I am well versed in the integration of biostratigraphic, oxygen isotopic, geochemical, seismic, and well log and production data for subregional and regional sequence stratigraphic and basin analysis.
