Reservoir Sedimentology and Stratigraphy of Continental Clastic Systems (Wyoming, USA)

Course Code: N027
Course Outline:  Download
Format and Duration
6 days


Continental clastic reservoir systems (aeolian, alluvial, fluvial, and lacustrine) account for at least 30% of the total known global hydrocarbon resource. Participants will be exposed to critical exploration and exploitation concepts for continental clastic reservoirs through a combination of outcrop exercises, classroom lectures, and core examination, all placed within an applied sequence stratigraphic context.  


Great course! - Loved the aeolian sections

Duration and Training Method

This is a six-day field course in NE Utah and SW Wyoming with classroom intruction (10%), core examination (10%) and outcrop visits (80%).  Exercises link outcrops with well log and seismic data.  Each day begins with lectures, followed by field visits. Participants will visit the Utah Geological Survey core repository, Dinosaur National Monument and Museum, and the world famous Ulrich’s Fossil Fish Quarry.

Course Overview

Participants will learn to:

  1. Compare successions in low accommodation settings to those in high accommodation settings.
  2. Evaluate the economic application of key concepts to predict play fairways, reservoir occurrence and behaviour, within a sequence stratigraphic model.
  3. Assess trapping styles and exploration strategies within continental clastic systems.
  4. Predict typical reservoir spatial relationships and lateral continuity for a broad spectrum of continental clastic sedimentary systems.
  5. Predict anticipated locales of most likely occurrences of major sediment conduits, based upon the sedimentary system and synsedimentary tectonic setting.
  6. Evaluate strategies for designing a geologically driven plan of depletion within a continental clastic reservoir.
  7. Compare the stratigraphic architecture and lateral variability of fluvial deposits resulting from variability in climate, tectonics, accommodation space and sediment supply.
  8. Compare fluvial, alluvial fan, aeolian and lacustrine facies both in core and outcrop.

This course provides the tools and approaches needed to identify and differentiate the diverse depositional environments encountered in continental clastic reservoir systems. Emphasis is placed on economic application of key concepts to predict play fairways, reservoir occurrence and probable reservoir behavior, all placed within the predictive power of the sequence stratigraphic model.

  • This day will include a stop at the Dinosaur National Monument Museum and Dinosaur Quarry

Day 6: Lacustrine settings

  • Fluvial-deltaic feeder systems
  • Conceptual models for lake formation (resulting from variability in climate, tectonic setting, and sediment supply)
  • Visit to Ulrich’s Fossil Fish Gallery - participants will have the opportunity to quarry for their own Fossil Fish from the famous Eocene Green River Formation
  • Synthesis – Reservoir prediction and exploration techniques
    • Prediction of continental clastic reservoir systems
    • Trapping styles

Day 7

  • Participants travel home

All geologists and geophysicists seeking training in applied clastic sedimentary geoscience as well as engineers who wish to broaden their geological knowledge with actual exposure to the reservoir styles they are analyzing. Valuable for asset team members working on continental clastic reservoirs and provides the opportunity to observe many examples of reservoir depositional features.  The course is also suitable for asset managers with repsonsibility for the exploitation of continental clastic reservoirs, in addition to technical support staff developing into the Geology and Geophysics disciplines.
