Fluvial and Shallow Marine Sandstone Reservoirs

Course Details

This course assumes no prior sedimentology background and systematically introduces participants in a landwards to basinwards transect through all environments of deposition where reservoir quality sands are deposited. For each environment of deposition they are shown modern examples, outcrop analogs, core photos, well-log signatures and seismic expression.

Besides presenting standard facies models, quantitative modelling equations are presented in exercises. By the end of the course participants will be able to predict reservoir geometries, dimensions, and N:G of fluvial and paralic sedimentary systems and look for stratigraphic traps.

We would strongly urge you to enroll in the equivalent field course to either ancient or modern clastics after completion.


The course is designed for geoscientists and reservoir engineers who primarily focus on fluvial and shallow marine successions, especially those involved in building or updating geomodels. Whether your task involves a simple well-correlation across tidal systems, or the input of fluvial channel dimensions into a geomodel this course will benefit you in several ways.

Course Outline

Day 1

Introduction to the course and sedimentary structures in fluvial to shallow marine successions.


Sequence stratigraphy of shallow marine siliciclastic systems. Exercise on description and interpretation of core facies.

Fluvial systems: classification of rivers, architectural elements, prolific global fluvial reservoirs, exercise on calculating channel dimensions and geometry using core or borehole image log data.

Day 2

Deltaic systems: Wave, Tidal, Fluvial processes, deltas through sea-level cycles, architecture, fan-deltas, gilbert-type deltas, shelf-margin deltas and supply of sand into the basin and reservoir prediction using clinoform trajectory analysis on seismic lines.


Exercise on the seismic facies of deltas

Day 3

Incised Valley Systems and Tidal Systems: Distribution of reservoirs and their vertical stacking patterns, exercise focuses on describing shallow marine core.


Exercise on collecting input parameters for geomodeling

Day 4

Barrier Islands, Shorefaces, Spits and Washovers: How to differentiate between each? Effects of stacking patterns on Kv and Kh, N:G changes,


Exercise on well-correlation

Day 5

Workshop on the identification of Gross Depositional Environments in well-logs.


Workshop on participant data

Available at a location of your choice. If you would like to schedule this course for your company we will need a minimum of 3 participants to run it.
