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.

Who Should Attend

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.
