Who should attend
and development geologists, geophysicists and reservoir engineers who need
essential understanding of reservoir and seal facies, geometry and architecture.
The course will review basic processes and will develop criteria for identifying
these reservoir and seal couplets from core, outcrop, and wireline data.
This course is designed to run before the companion course "Concepts and
Applications of Sequence Stratigraphy" (three days) and together these
form a 5-day course.
transport and deposition, naturally occuring flows, sedimentary facies
and structures (bedload, suspension, mixed)
2. FLUVIAL DEPOSITIONAL
alluvial fans, braided rivers, meandering rivers, anastomosing river systems,
crevasse splays, the significance of "flood" deposits, floodplains, peat
mires (coal), palaeosols
SHORELINE DEPOSITIONAL SYSTEMS
and sedimentary processes and facies, delta morphology and sedimentation
patterns, delta scale, delta cycles, delta types, mouth bar development
versus distributary channels, lacustrine deltas, shoreline deposits, barrier
islands, tidal delta, lagoons. Criteria for distinguishing deltaic distributary
channels from fluvial channels.
and processes, storm deposits, shelf tidal deposits, mixed siliciclastic-carbonate
DEEP SEA DEPOSITIONAL
processes, turbidites, contourites, deep sea fan deposits, canyons, feeder
channels, levees, lobes, basin plain, relationship with relative sea level,
catastrophic events, olitholiths.
GEOMETRY AND ARCHITECTURE
(a whole suite including modern and ancient), Width/Thickness ratios for
different depositional systems, Interconncectedness, Relationship between
facies and reservoir quality (flow units), Reservoir orientation via mapping
and palaeocurrent analysis, sand percent/thickness plots,
of reservoir sedimentologic analysis to exploration and reservoir
based on modern analogues (using well data and high resolution seismic),
and ancient examples from basins throughout Australia, South Africa, Indonesia,
Venezuela, Spain, USA. Hands-on interpretation of wireline logs and core
photos (can run with a core workshop if deemed appropriate).
