Why Choose this Training Course

This is a 5-days training course. Sedimentary rocks and their depositional environments are fundamental to all aspects of petroleum geoscience, including evaluation of the petroleum system, exploration, field appraisal, reservoir characterisation and development, and solving production issues. Equally, they are fundamental to the study of stratigraphy, mineral resources, water resources and global environmental change.

Sediments deposited in rivers and deserts, deltas and deep-sea fans, coasts, shelves and contourite drifts, bioherms and carbonate platforms, all differ significantly in their rock properties, diagenetic character, heterogeneity and architecture. Such differences are key to understanding their behaviour as source rocks, migration pathways, reservoir rocks and seals, in both conventional and unconventional hydrocarbon systems.

env covers clastic, carbonate, evaporite and volcaniclastic sediments, and the full range of settings in which they are deposited – including continental, shallow marine and deepwater depositional environments. Careful consid-eration is given to the principal diagnostic features of sediments from the main environments – in the field, in cores/bore-holes, and in modern systems. Rock features include sedimentary structures, textures, composition, petrophysical charac-teristics, and biogenic/organic content. For each environment, selected wireline logs will be examined, and the overall rock geometry or architectural elements discussed. A series of case studies will illustrate a range of hydrocarbon fields and plays from each of the main depositional environments.

The presentations are fully illustrated with high quality colour images of sediments and sedimentary rocks from a wide range of modern, ancient and subsurface examples.
The course will build on the handbook Sedimentary Rocks in the Field (Stow, 2005) and the new edition in preparation, Sedimentary Rocks in the Field and Core (Stow and Gerard, 2021). Each participant will receive a copy of the latest revised edition of this book as well as a full set of the PowerPoint presentations.
