Course Details
Deltaic Successions produce hydrocarbons worldwide from reservoirs in the North Sea (Brent, Brage, Oseberg), the Barents Sea (Knurr FM), Alaska North Slope (Prudhoe Bay Field), Onshore India (Barmer Basin), Lower Indus Basin (Sembar and Lower Basal Sands), Venezuela (Budare Field, Lagunillas Field).
A series of world-class outcrops have been picked from the Colorado Rockies and Book Cliffs of Utah. Participants will be able to see:
1. Distributary channels (single, multistorey and multilateral).
2. Terminal mouth bar sandstones
3. Delta plain paleosols
4. Trangression of deltaic over fluvial strata
5. Compensation stacking of deltaic lobes
6. Fan deltas
7. Growth Faults
Many of the outcrops selected for this course are ‘seismic-scale’ and participants will spend time correlating outcrop photopanels with seismic facies from industry data.
By the end of the trip you should be able to:
1. Identify deltaic lithofacies in core, and high N:G seismic facies
2. Predict variations in N:G along depositional strike and dip.
3. Determine which sand and gravel bodies make the best reservoir and whether they are connected or compartmentalized.
4. Permeability relationships in channels vs terminal distributary bars.
5. Understand stratigraphic traps in deltaic systems
This is field trip that focuses specifically on deltaic systems, if you would like a more generalized field trip on shallow marine reservoirs, such as shorefaces, tidal channels, barrier island etc, please click here.
If you are working on coarse-grained gilbert-type deltas we can change the itinerary given below to accommodate you. Instead of spending three days in the Ferron Sandstone we will take you to Colorado and show you some spectacular examples of coarse grained turbidites and debrites associated with rift-associated deltas.
Who Should Attend
• Geologists
• Geophysicists
• Petrophysicists
• Engineers
The course is designed for geoscientists and reservoir engineers who primarily focus on sub-surface deltaic successions.
