Who Should Attend:

This course is designed for petroleum geologists, geophysicists, and engineers who have a basic understanding of depositional systems and stratigraphic principles but desire a stronger working knowledge of sequence stratigraphy, based on a hands-on field experience.

Course Description:

The Book Cliffs of Utah have become the premier locality globally for field teaching of sequence stratigraphy. Continuous, well-exposed and easily-accessible outcrops make it possible to analyze facies relationships of stratigraphic sequences in great detail, both in terms of lateral variation (systems tracts) and vertical stacking patterns (parasequences). Most significant clastic depositional systems are represented, including meandering, braided, and anastomosed fluvial; fluvially- and wave-dominated deltas; transgressive and regressive shorefaces, tidally-dominated estuaries, and deep-water mudstones. This makes the Book Cliffs an excellent classroom to study the interrelationship between eustatic and tectonic development of accommodation space and subsequent filling by clastic sediment.

The Book Cliffs region is often cited as an analog for subsurface exploration, particularly in foreland basins, and sequence stratigraphy has become one of the leading methods for correlating and mapping depositional packages, leading to significant discoveries of petroleum in fields that had been abandoned, as well as new discoveries. To that end, this course is directly applicable to the exploration, characterization, simulation, and development of petroleum reservoirs. Specifically, this course gives participants an opportunity to view sequence stratigraphic features directly in outcrop, giving a better perspective when making similar interpretations based on cores, logs, and seismic sections. This course would be particularly valuable to geologists who have had limited exposure to real rock bodies.

The course runs five days, with a format consisting of early morning instructional sessions at the hotel, followed by further instruction and completion of exercises in the field.

 Course Content:

  • Review of concepts and principles associated with sequence stratigraphy (significant surfaces, systems tracts, stacking patterns, relationships between space production and filling)
  • Hike through a series of “stacked” parasequences to illustrate the repetitive character of facies associations and discuss their relationship to space production
  • Measure and correlate multiple sections within a single parasequence to illustrate the concept of a systems tract
  • Follow individual parasequences along depositional dip to demonstrate lateral facies changes from coastal plain fluvial through shoreface/deltaic to basinward pinchout into marine deposits
  • Produce an outcrop facies map (architectural analysis) of a full depositional sequence
  • Discuss auto- vs. allogenic depositional controls (base level, eustasy, tectonics, compaction, climate) on sequence development
  • Use multiple-working hypotheses to demonstrate the possibility of more than one reasonable interpretation of the same succession

 Schedule:

  • Day 1: General principles and concepts of sequence stratigraphy, introduction to stratigraphy and setting of the Book Cliffs (Price River Canyon)
  • Day 2: Concept of a systems tract (Gentile Wash and Spring Canyon)
  • Day 3: Concept, identification, and significance of parasequences and stacking patterns (Woodside Canyon)
  • Day 4: Down dip facies changes and Facies mapping (architectural analysis) of a full sequence (Battleship Butte to Thompson Canyon)
  • Day 5: Core analysis (Utah Geological Survey – Salt Lake City)
