STEPS Theme 1 - Source to Sink Analysis

The first annual STEPS Theme was “Source to Sink analysis.” This involved examining the transfer of material from mountain ranges and elevated continental areas, transport and storage of that sediment and ultimately its deposition in sedimentary basins.

STEPS project listing for 2017

Project ID
Question/Thesis title
S2S_1
Examining sediment dispersal patterns in transform margins where there is limited hinterland relief available (spatially limited input areas and with sediment infill and burial controlled by active tectonics in the basin rather than transport mechanisms).
S2S_2
Douala and Rio Muni basins: Identifying the depositional system segments with the highest probability to contain sediments with good reservoir characteristics (sediments source character).
S2S_3
Evolution of a region affected by complex (plates convergence) tectonics; effects on Petroleum Systems distribution and efficiency.
S2S_6
Regional assessment of lithological variation within the Eagle Ford Group, Gulf of Mexico, implications for unconventional reservoirs.
S2S_7
Is first pass Source to Sink investigation utilising machine learning achievable?
S2S_8
Source to Sink studies in the Barents Sea: Predicting sand quality from regional understanding of the hinterland to provide inputs for basin screening.
S2S_9
Reconstructing Triassic sedimentation pathways of the Circum-Arctic: Utilising geodynamic reconstructions and Source to Sink analysis.
S2S_10
Understanding the impact of diachronous collision on clastic reservoir development along the sub-Andean trend.
S2S_11
Does the Late Cretaceous switch from longitudinal (Chukotka source) to transverse (Brookian source) sediment supply recorded in the Arctic Alaskan Foreland Basin influence reservoir potential?
S2S_12
Exploring the Jurassic reservoirs of the Troll Field, Norwegian North Sea (Combining detrital geochronology with detrital thermochronology and subsurface data).
S2S_13
Investigating the cause of low TOC in the Silurian resource play, Poland.
S2S_14
Using the geodynamic context and uplift history to make predictions about drainage on the North Atlantic margin and impact on reservoir quality.
S2S_15
Can numerical landscape evolution models and thermochronometry methods be used to accurately predict offshore sediment flux?

These studies encompassed a vast array of parameters and data, allowing the researcher to get an enhanced view of the architecture of the depositional system, the likely character of the sediment (composition and variability) and its hinterland.

These studies are particularly beneficial to those exploring for hydrocarbons and can enable:

  • Regional understanding of basin architecture: paleo-shelf morphology, drainage pathways, etc.
  • Identifying the key periods of uplift and erosion, and the resulting intervals of highest sedimentation rates (understanding the duration of lag). Identification of sediment input points (point source versus reworking on shelf) and how these change over time.
  • Mapping and predicting the distribution of sands and their thickness.
  • Predicting clastic reservoir quality from hinterland characteristics.
  • Timing of provenance switches, the sediment source and impact on reservoir quality.
  • The utilization of these data types as input parameters for basin modelling.
