Sediment Modelling

Monte Carlo simulation to numerically model sediment deposition patterns as a result of low-density turbidity currents.

The Sediment Modelling module uses a workflow driven approach to guide the user through simulation of 3D turbidity flows on present-day and palaeobathymetric surfaces. Sediment deposition modelled as a result of these flows can be used to understand and predict reservoir geometry, distribution and quality. Simulated flows are validated against existing well data to allow extension of distribution and properties of predicted flows to areas with no well control, thereby significantly reducing reservoir uncertainty. Validated results can be used to aid identification of satellite prospects and optimize drilling programs.

Full integration of the Sediment Modelling workflow with the 3D Kinematic Modelling tools in MOVE provides a unique capability to carry out sediment modelling on a restored palaeobathymetry at time of flow. The palaeobathymetric surfaces with associated reservoir quality attributes can then be structurally forward modelled to assess the distribution of turbidite-hosted reservoirs in the present day.

Sediment Modelling

  • Run Single Flows to test a fixed set of Flow Parameters determined from known geological history of the area.
  • Sensitivity Flows can be run to analyse changes associated with variation of the inflow Flow Parameters. Short run times means multiple scenarios can be quickly tested with a range of input parameters.
  • Aim to achieve best fit with well data and relevant seismic attribute data.
  • Generate stacked flows to reduce uncertainty associated with lateral reservoir connectivity and stratal stacking patterns.
  • Results on palaeobathymetric surfaces include generation of reservoir quality indicator maps and 3D surfaces.
  • Integration with the Kinematic Modelling modules allows the user to assess the interaction between tectonics and sedimentation and to forward model resultant attributes and surfaces to assess their present day distribution.
  • Carry out quantitative analysis of reservoir quality indicators such as net-to-gross and grain size distribution.
  • Export surfaces for use in basin and reservoir modelling.
