Depositional Regimes and Reservoir Architectures Using Seismic Techniques

Course & Workshop

May 20 – 25, 2023

(Six Days)

Instructor: Dr. Mohamed Darwish (Ph.D)


Who Should Attend

The course is designed for all geologists, geophysicists, petrophysicists and reservoir engineers.

Course Content

The course throws light on the concept of sequence stratigraphy and the configuration of different siliciclastic depositional regimes in response to the seal level changes, sediments influxes and wave and tidal energy. Coastal, shallow marine, and deep marine depositional settings are discussed and illustrated with examples of modern depositional regimes (photos), seismic, well-logs, and outcrop data (photos).

Learning Outcomes:

  • Learn to recognize in well logs the various systems tracts, sequence boundaries, transgressive surfaces, maximum flooding surfaces, and maximum regressive surfaces.
  • Learn to interpret the most likely depositional regimes from well logs and prediction of laterally preserved sedimentary facies.
  • Learn to identify on seismic the different types of systems tracts, sequence boundaries, maximum flooding surfaces, and stratal termination patterns.
  • Learn to recognize in outcrops (photos) the significant surfaces: SB (sequence boundaries), MFS (maximum flooding surfaces), and MRS (maximum regressive surfaces)

Fundamental Concepts

  • Controls on relative sea level change, accommodation space and clastic input.
  • Sequence boundaries: definitions and types. Maximum flooding surfaces, transgressive surfaces, and other surfaces of sequence stratigraphic significance.
  • Seismic stratal termination patterns and seismic facies.
  • Progradation, aggradation and retrogradation, shoreline trajectories.

Depositional Environments and Systems Tracts

  • The falling stage systems tract related depositional regimes:

Forced regression, submarine canyons, mass flow complexes, shelf margin deltas, submarine fans and channel levee complexes.

  • The lowstand systems tract related depositional regimes:

Incised valleys and incised valley fills, fluvial depositional systems, lowstand wedges and shelf margin deltas.

  • The transgressive systems tract related depositional regimes:

Back barrier complex regime, estuarine depositional systems, bayhead deltas, and transgressive open coastal shorelines.

  • The highstand systems tract related depositional regimes:

Strand plains and beach ridges, inner shelf deltas, and normal regressive open coastal shorelines.

  • Main delta types in response to dominant processes.


First day will be held at the Holiday Inn Maadi Hotel, in Cairo. The participants will fly the next day to Hurghada. The course will be continued in Hurghada.


Course Fees

Inclusive of refreshment and lunch at the Holiday Inn Maadi Hotel. Air Ticket Cairo/Hurghada return and accommodation in Hurghada.
