Reservoir Characterization in Modern Environments
This training presents the reservoirs that are deposited in modern environments, ranging from fluvial to estuarine (tide- and wave-dominated) and coastal marine, at exploration and production scales.
This training presents the reservoirs that deposited in modern environments, ranging from fluvial to estuarine (tide- and wave-dominated) and coastal marine, at exploration and production scales.
You will visit world-class shallow water environments of deposition and acquire an in-depth knowledge of the reservoir geo-bodies formed in these environments:
- In the Gironde estuary, a worldwide reference model for tide-dominated incised valleys, reservoirs will be examined at exploration scale along a 200 km long facies transect, from fluvial point bars to heterolithic estuarine point bars and tidal bars, and to the tidal inlet channel-fill located at the estuary mouth. The exceptional core and very high resolution seismic database allow describing the reservoir geo-bodies at production scale (geometries, heterogeneities).
- In the Arcachon estuary, a wave-dominated incised valley, tidal channel reservoirs and tidal flats will be examined along a 40 km long facies transect, from the inner estuary where small-scale meandering tidal channels incise a mud flat, to the outer estuary where larger tidal channels incise a sand flat and amalgamate seaward to generate a large-scale tidal inlet channel-fill at the estuary mouth. Here again, the exceptional core and very high resolution seismic database allow describing the reservoir geo-bodies at production scale (geometries, heterogeneities).
- In the Atlantic wave-dominated oceanic coastline, adjacent to these embayments, beach, shore face and aeolian coastal dune deposits will be presented thanks to spectacular trenches in the backshore and foreshore, cores and GPR lines.
By the end of this course, participants will be able to:
Learning-by-doing, based on extensive exercises during the field trip. The teaching material is composed of field guide books, power point presentations, poster sessions (before and after each field stop), core descriptions (high-quality cores, preserved in epoxy), very high resolution seismic lines, and production geology exercises.
Each participant is required to provide a yearly medical certificate before attending this field course. Participants must be in good health and physical conditions to attend.
Attendees must also wear adapted shoes (suitable for sandy and wet shore) and bring clothing for hot day time temperatures (sun hat, sun glasses, etc.).
This course is open to any geoscientist with a basic knowledge of geology, and any participant at bachelor or master level.
It has been specially designed for direct application by exploration and production geologists / geophysicists, working on shallow water reservoirs, ranging from fluvial, estuarine, to shore face deposits. Reservoir engineers in charge of modelling and producing these reservoirs should be interested also.
