Business impact: This course considers fluvial, alluvial fan, and lacustrine depositional systems as exploration targets and in terms of field development. The controls on these systems will be assessed at a variety of scales to aid the understanding of the distribution of source rocks and reservoir units in continental basins.
Topics covered include stratigraphic analysis and correlation, tectonic, climatic and base level controls on facies distributions, system-scale variations in sandstone body architecture, and dimensions and connectivity of reservoir units. Exercises based on subsurface data form a key element of this workshop.
Duration and Training Method
This is a classroom or virtual classroom workshop comprising seminars, case study presentations, workshops discussions, and exercises of varying duration.
Participants will learn to:
- Understand the characteristics of alluvial fan, fluvial and lacustrine systems in sedimentary basins.
- Evaluate and integrate the controls on lacustrine and fluvial depositional systems.
- Develop tools for the prediction of field-scale distribution of reservoir units.
- Analyse the variation in stratigraphic architecture of fluvial successions in terms of connectivity within a reservoir.
- Evaluate the different scales of heterogeneity in fluvial successions and their effects on reservoir quality.
- Use appropriate correlation techniques in fluvio-lacustrine systems.
- Assess tectonic controls on basin margin alluvial fan characteristics.
- Integrate different data types in the analysis of continental depositional systems.

Who Should Attend and Prerequisites
The course is aimed at relatively experienced exploration and development geoscientists, petrophysicists, and reservoir engineers.
Phil left BP after 32 years working as a sedimentologist, latterly as the global discipline lead for sedimentology, stratigraphy, and reservoir quality. He is now an independent consultant focusing on clastic reservoir challenges and geoscience training. He is also involved in delivering lectures and supporting fieldwork for the Royal Holloway Petroleum Geoscience MSc.
Phil completed a PhD on the structural controls and alluvial architecture of Tertiary sediments in the Ebro Basin, Spain. Following this, he began work as a continental sedimentologist. As a sedimentologist in BP, Phil worked across the BP international portfolio from Argentina to Alaska and Australia to Sakhalin and many points between. He has contributed to the reservoir descriptions in access, exploration, and development ventures with frontier field work being an important component; this has included field work in Turkey, Yemen, Sakhalin, Algeria, Jordan/Saudi Arabia and Brazil.
Phil has evaluated many of the more complex depositional and diagenetic issues in BP, such as opaline deposits, tuffaceous sandstones, and the role of chlorite in sandstones. However, it is the glacial reservoirs of North Africa and the Middle East that have been a particular favourite area of study. He co-edited the Geological Society, London 2016 Special Volume No 436 "The Value of Outcrop Studies in Reducing Subsurface Uncertainty".
