Basin Dynamics

Over the last decade, major advances have been made in the understanding of sedimentary basin dynamics. Badleys have collaborated with the Earth Structure & Geodynamics Group at Liverpool University since the late 1980's, developing techniques and software for the large-scale analysis of rift basins and passive margins which are used mainly as an exploration tool.


Software:

Our range of in-house software for basin dynamics include:
 

  • STRETCH for forward modelling the development of rift basins
  • FLEXURAL DECOMPACTION 2D for backstripping and restoring 2D cross-sections across rifts and passive margins
  • FLEXURAL DECOMPACTION 3D for backstripping and restoring 3D maps and grids across rifts and passive margins
  • HEAT a whole-lithosphere thermal modelling prorgramme


    How we can help you
     

    QC Interpretation: Help with seismic interpretation by constraining difficult-to-interpret and difficult-to-image deep structure and stratigraphy.
     

    Understanding Basin Dynamics: Understand and predict the large-scale processes driving subsidence, uplift and heat-flow in a basin.
     

    Palinspastic Restoration: Produce sequential, isostatically-balanced cross-sections (2D) or maps (3D) depicting stratigraphic, fault-block and basin geometries.
     

    Palaeobathymetry: Predict and map out variations in bathymetry, basin-floor slope and depocentre location through time.
     

    Depositional & Erosional Analysis: Model syn-rift structural elevation (footwall uplift) highlighting sediment source areas and predict amounts of erosion at fault-block crests. Quantify the effects of sediment loading and compaction on stratigraphy. Generate burial history plots across a basin.
     

    Temperature History: Evaluate a basin's temperature history from beta-factor and heat-flow profiles generated by both forward and reverse modelling. Predict top basement and top sediment heat-flow and horizon temperatures through time. Calibrate vitrinite and downhole temperature against a tectonic/thermal model.
     

    Gravity modelling: Compare structurally-derived predictions with measured gravity models.


    Badleys worldwide experience in Basin Dynamics:


We have used these methods to investigate basins from a diverse geographical range including, NW Europe, Red Sea, Vietnam, South China Sea, Australia, South America, Eastern Canada, Ukraine, East Africa, Aegean Sea. Data requirements for an analysis are regional cross-sections for 2D modelling, or a suite of regional maps/grids for 3D modelling.
 

It is often possible to get quick-look forward and reverse modelling results from one or more 2D profiles in just a few days. 3D studies are more complete and will take somewhat longer than a 2D quick look, but can still deliver results quickly if the data are there to work with.
