Longterm research topics and
technology needs
•
|
|
Predictative models for architecture (and variability) in fluvial sequences, to support analysis and modelling of reservoir communication |
|
|
Analysis of controlling factors for the development of fluvial sequences, including the effects of climatic fluctuations and variability. |
|
|
Sedimentary architectures and grain-size distributions in
shore-face deposits, and their role for porosity/permeability preservation
in quartz cemented reservoirs. |
|
|
Basin scale tectonic influence on development of sedimentary
systems and stratigraphy. Emphasis on the effects of variable subsidence
at both basin and local scales. |
|
|
Sedimentary controls on porosity and permeability distributions in carbonates |
|
|
Regional synthesis of the Brent system (has been done several times before, but should be revisited). |
|
|
Biofacies as indicators of depositional environmental – use dataset from wells with low exploration follow-up potential |
|
|
Trace fossil and ichnofacies studies - produce an Atlas |
|
|
Gravity flow transport processes - modeling research: plume tank experiments and/or simulation modeling |
|
|
Slope
to deep-water sedimentary architectures – document ideas and
interpretations on controls on contrasting systems. Continuous effort and
follow-up or extension of the digital database project |
|
|
Seismic modelling studies of various sedimentary architectures/systems
from field analogues coupled with rock properties from subsurface datasets |
|
|
Chlorite cementation and the need to prognose reservoir quality in chlorite cementated reservoir. |
|
|
Mechanisms for porosity preservation vs. depth in the Fangst Group in Haltenbank Area |
|
|
Compressibility of reservoir sandstones during production |
|
|
Relationship between sonic (and seismic) velocities (P and S wave) and sandstone diagenesis |
