An Introduction to Sequence Stratigraphy (G068)

Tutor(s)

Gary Hampson: Professor of Sedimentary Geology, Imperial College London.

Overview

Sequence stratigraphy is a key tool for subsurface interpretation of depositional systems and thereby predicting the distribution of reservoir, source rock and seal lithologies. The course will introduce the principles and methods of sequence stratigraphy, with a focus on continental, shallow-marine and deep-marine depositional settings. Participants will apply these principles and methods via the sequence stratigraphic interpretation of subsurface data (e.g. seismic, well-log, core, reservoir production data).

Introduction to Clastic Facies (G073)

Tutor(s)

Howard Feldman: Consultant Geologist, Feldman Geosciences LLC; Affiliate Faculty, Department of Geosciences, Colorado State University.

Overview

This course provides an introduction to siliciclastic facies in all aqueous settings, focusing on sand deposition for application to conventional reservoirs. The course begins with an overview of sedimentary structures and their recognition in outcrop and core. Observations of sedimentary structures and facies stacking patterns are then used to interpret depositional environments and make predictions about sand body geometry, size, and compartmentalization. The course makes extensive use of large-format (50% scale) core photos and outcrop photopans from a wide range of environments. Subsurface data sets, including seismic and well logs, are used to illustrate the application of these concepts to subsurface mapping. We will also cover an introduction to core description workflows.
