Course Description

The prime focus of this 2-day course is to use the Recent and Late Pleistocene - a classic high stand-low stand combination – to develop the basic clastic depositional models for all the various reservoir types we explore for and develop. This course will develop the depositional models for 19 clastic reservoirs, virtually all that you will ever explore for or develop as a field.  For each reservoir, we will start by looking at the depositional processes, core and log signatures, and reservoir geometries in the recent and apply these observations to both outstanding outcrops and then the subsurface using logs, maps, and where available good seismic.

The course will summarize the vast amount of information available for each reservoir system and provide the “ground truth” that can be used in the subsurface. For each reservoir type we will:

  1. Review the PROCESSES that control sediment movement and deposition in that environment.
  2. Study the resulting DEPOSITIONAL RECORD from continuous cores through the reservoirs and GEOMETRIES characteristics of each unit.
  3. Document the LOG RESPONSES using the actual logs run in the modern sands.
  4. Establish the FACIES and SEQUENCE STRATIGRAPHIC CONTEXT for each unit.
  5. Translate these observations to applications in the SUBSURFACE with emphasis on TRAP TYPES and SEISMIC SIGNATURES.

The reservoirs we will examine in detail are:


Alluvial Fan


Braided (includes Incised Valleys)


Coastal Regressive
Transgressive (coastal and offshore)
Shallow Marine Shelf


River Dominated
Wave Dominated
Tide Dominated
Special Case: Shelf Margin Deltas


Submarine Fans

The course is not an academic course, but is meant to be practical and hard hitting – how to realistically use log, rock data, and seismic to make reasonable interpretations in the subsurface.
