Well-exposed exposures of the Pyrenean Foreland Basins in northern Spain offer unique opportunities to observe a range of different styles of sand- and mud-rich deepwater slope-to-basin-floor depositional systems and the linkages to updip shelfal and fluvial delivery systems. This course combines field activities with core examination, lectures, and exercises in deepwater systems, including subsurface examples from the North Sea, West Africa, and the Guyana-Suriname Basin. Field activities focus on deepwater lithofacies descriptions, stratal geometries, and practical applications for recognising key stratigraphic surfaces.
Participants describe core and integrate outcrop (including 3D virtual models), core, and well-log information with seismic data to generate high-resolution maps of reservoir styles in different deepwater settings. Engineering data is utilised to emphasise how this type of information can improve the prediction of reservoirs and their performance. Play fairway mapping of regional source-to-sink systems is used to discuss reservoir, source, and seal play-scale risking. Course examples include core, well-logs, and seismic datasets that are compared and contrasted with extensive outcrop exposures to help participants extrapolate 2D outcrop information into 3D views of reservoir-scale depositional systems using high-resolution photogrammetry models of the outcrops. Aspects ranging from frontier exploration, through discovery appraisal, to field development are discussed.
Schedule
Duration and Training Method
This is a field course in the Pyrenean Foreland Basins. Fieldwork includes presentations, sedimentological exercises, modelling exercises, and discussions. Short classroom sessions comprise a core visit, subsurface case studies, and reviews of the fieldwork.
Course Overview
Learning Outcomes
Participants will learn to:
- Evaluate the sedimentological processes of transport, erosion, and deposition in deepwater depositional systems and their impacts on reservoir architectures.
- Describe deepwater lithofacies and relate them to stratal geometries.
- Risk reservoir presence and seal adequacy for prospects and field segments.
- Interpret deepwater environments of deposition based on lithofacies associations and stacking patterns.
- Utilise outcrop analogues and depositional models to understand the 3D distribution of reservoir facies.
- Correlate rock properties to facies and build geologic models.
- Perform facies mapping to highlight impacts on reservoir performance during appraisal and production.
- Integrate play-scale assessments of reservoir, source, and seal within a source-to-sink stratigraphic context.
Course Content
- Interpret depositional settings and related reservoir architecture and lithofacies associations.
- Interpret sequence stratigraphic surfaces in outcrop, logs, and seismic within deepwater settings.
- Use core and well logs to interpret environments of deposition.
- Evaluate reservoir geometry and connectivity in different depositional environments.
- Apply interpretation and mapping techniques for core, well logs, and seismic lines in deepwater settings, from exploration to production scales.
- Develop mapping strategies for reservoir, source, and seal play elements in deepwater settings.
- Identify and map play fairways within a sequence stratigraphic source-to-sink context.

Rene Jonk
Background
Rene Jonk has more than 25 years of experience in geoscience characterization for petroleum exploration, development and research, having held technical advisor and leadership roles with ExxonMobil and Apache. He has worked extensively across offshore basins of the African and South American margins, as well as the North Sea, onshore North America and the Mediterranean areas. His experience spans across onshore and offshore regions, research, exploration and production, and both conventional and unconventional reservoir systems. Rene’s holistic approach to depositional systems allows him to work across reservoir, seal and source evaluations, at basin to field compartment scales.
Both at ExxonMobil and Apache Rene was responsible for stewarding, developing and delivering classroom and field-based training in stratigraphy and sedimentology, including seismic stratigraphy, clastic reservoir sedimentology, fine-grained rock (seal, source and reservoir) characterization, and deep-water depositional systems. Rene delivered these courses internally, as well as to external student audiences, including the SEPM short course on sequence stratigraphy.
Rene is an honorary professor at the University of Aberdeen, where he teaches formal courses on seal evaluation and reservoir characterization with application to petroleum geology and CCS, mentors Petroleum Geology M.Sc. and Ph.D. projects and is a consultant with the Sand Injectite Research Group. He is an active member of SEPM, EAGE and the Geological Society of London.
