N156 Clastic Depositional Systems in a Basinal Framework: Exploration and Reservoir Implications (Pyrenees, Spain)
N156 Clastic Depositional Systems in a Basinal Framework: Exploration and Reservoir Implications (Pyrenees, Spain)
A field course analysing the distribution, architecture, internal characteristics, and reservoir quality of sandstone bodies from a wide range of clastic depositional environments. The depositional settings examined occur in two regional scale sediment transport paths and include alluvial fan, fluvial, tidal- and wave-dominated shorelines/shelves and deepwater (within a well constrained basinal framework). Emphasis is on the spatial distribution of different depositional settings as controlled by the basinal framework, and reservoir attributes of sandstone bodies in different settings.
This is a six-day field course in the Spanish sector of the Tertiary basins in the Pyrenean mountain belt, comprising field examination of depositional systems at both seismic and, more commonly, sub-seismic, sandstone body scale. Consideration of correlation strategies in a wide range of depositional systems will be an important theme. The proportion of field time to classroom time is approximately 90:10. This course will also make use of Digital Outcrop Imagery (DOI).
Participants will learn to:
Fluvial depositional systems
We will undertake a holistic analysis of fluvial systems and their deposits, from hinterland source to depositional sink using two regional scale fluvial systems in the Spanish Pyrenean mountain belt i) Eocene axial, thrust-sheet-top fluvial systems (Tremp-Graus-Ainsa sub-basins); and ii) Oligo-Miocene transverse fluvial systems, feeding into the Ebro foreland basin. The Eocene fluvial system was directed axially along the mountain belt and accumulated more than 1000 m of strata in a thrust sheet top basin. This system was an open system that was coupled down-dip to coastal plain, shoreline and deeper water marine systems. In contrast, the Oligo-Miocene fluvial system was a closed, terminal system directed transversely across the mountain belt. Major fluvial dispersal systems were guided from the hinterland to the Ebro foreland basin. These systems were complemented by more localised fluvial systems produced by actively uplifting structures, particularly at the emergent thrust front. The course will examine the deposits of both of these regional scale fluvial systems in terms of individual sediment bodies, their architecture and connectivity.
Tidally influenced depositional systems
The distribution of tidally influenced depositional systems and sandstone bodies in the Pyrenean basins is strongly controlled by basin configuration. This will be demonstrated via two examples of tidal deposits (Baronia Formation, Ager Basin and Roda Sandstone, Tremp-Graus Basin). The geometry and internal characteristics of these two quite different tidal influenced sandstone bodies will be addressed. Criteria for the interpretation of tidal sandstone facies will be demonstrated and the nature and distribution of permeability barriers and baffles will also be discussed.
Deepwater depositional systems
Deposits of deepwater systems dominate the Ypresian and Lutetian fill of the the Ainsa and Jaca basins and show down-dip changes from slope canyons and channel complexes associated with mass transport complexes, to lobe and basin plain turbidites that include exceptional, megaturbidites. Observations will range through bed-scale depositional element and element stacking scales. Outcrop observations will be complimented by a series of exercises, including synthetic seismic model interpretation and detailed correlations, a view to facies modelling methods and role of heterogeneity, as well as seismic examples from potential analogues.

Day 6: Ebro Basin: a closed, terminal continental basin: basin centre and basin margin alluvial depositional systems
Day 7
Geologists and geophysicists who wish to gain insights into the nature of a wide range of reservoir analogue sandstone bodies in a basinal context.
There are no prerequisites for this course, but it is a natural extension of Basic Application Level course N155 (Introduction to Clastic Depositional Systems). Participants may wish to attend courses (at Skilled Application Level) exploring in greater detail outcrops visited on this course. These include the fluvial course N108 (Exploration and Geological Model Development in Fluvial Reservoirs) and the deepwater courses N028 (Sand-rich Turbidite Systems and Megaturbidites: From Slope to Basin Plain. Facies, Stacking Patterns and Controlling Factors). The field-based reservoir development and modelling course N335 (Modelling Clastic Reservoirs) also visits the same outcrops. N156 gives the early/mid career geoscientist the necessary background knowledge and skills to prepare for and consider the diverse range of Skilled Application Level classes on the Clastics portfolio.
The physical demands for this class are LOW according to the Nautilus Training Alliance field course grading system. Access to the outcrops is easy with the majority being roadside stops. The longest walk on the field course is approximately 3 km (1.8 miles) along a hillside track and across scrubby hill land. Other short walks of up to 0.25 km (.01 miles) take in scrubby hill land and dry stream beds. Participants should be aware that some localities are at an altitude of around 1000 m (3000 ft)and field temperatures may exceed 25 degrees celsius.

Background
He worked as an independent consultant for 11 years, contracting regional geological mapping projects for the Servei Geologic de Catalunya and outcrop analogue research projects for various oil companies. From 1998 he has been working as a researcher in sedimentology for the Geomodels–Geodynamics and Basin Analysis Group (Universitat de Barcelona). From 1989 Pau has been leading field courses for the oil industry and academia, mostly in the Pyrenees and Ebro basin.
His main research experience is in the areas of sedimentology and stratigraphy of terrigenous depositional systems, with special focus on deepwater successions of the south-Pyrenean Foreland basin, paired with its 3-D modelling as hydrocarbon reservoir analogues. His current interests include fluvial megafan, delta, and carbonate slope deposits, as well as new techniques used to improve their characterization. He is also participating in research programs oriented to the evaluation of potential CO2 traps in a variety of basin settings.
