Objectives and deliverables

Overall aims

University of Manchester

Integrate high resolution sequence stratigraphy with quantitative hierarchical architectural analysis of an exceptionally well exposed fluvial reservoir analogue in order to provide an improved understanding and database for reservoir prediction in exploration and 3-D reservoir modelling for field development planning.


Build a chemostratigraphic correlation framework between outcrops and critically test this correlation against the physical stratigraphy, thus developing an integrated approach to correlation non-marine systems. To explore chemical ‘facies’ and their link to depositional facies.

University of Western Australia

To develop a magnetostratigraphic framework for the lower Beaufort Group and to integrate this with the physical and chemical stratigraphic studies to investigate rates of deposition, palaeoclimatic cyclicity and any facies controls on magnetic behaviour. To undertake radiometric dating of interbedded ashes to embed an absolute chronostratigraphy


To investigate cyclicity on the study sections with a view to palaeoclimate modelling and correlation.

Synthesis of these project strands will provide a step-change in our understanding of and approach to stratigraphic (therefore reservoir) prediction in non-marine fluvial strata.

University of Manchester: detailed objectives

  • To document the response of fluvial systems to changing accommodation and to develop predictive models using this approach, for vertical and lateral connectivity;
  • To develop a better understanding of the connectivity between channel and overbank sandstones under different net:gross regimes and for different stacking patterns;
  • To examine the linkages between accommodation and climate change (for example, if gradient increases but climate dries, the response might not be the usual higher net:gross channel systems);
  • To investigate the fluvial-lacustrine transition (and possible brackish marine) in terms of changes in fluvial style with transgression;
  • To record lateral changes in grain size, sedimentary structures, bed thickness and net:gross between channel axis and margin;
  • To develop a hierarchical scheme for fluvial reservoir description and interpretation based on outcrop logging and application/testing of this approach on any available Chevron core;
  • To link this scheme to stratigraphically important surfaces (sequence boundaries, nonmarine flooding surfaces) and to stacking patterns;
  • To collect a stratigraphically embedded quantitative database of geometries, aspect ratios, vertical and lateral proportion curves and architectural element diagrams;
  • To asses any linkage between the nature of overbank deposits and channel geometry and stacking patterns and to accurately characterize thin beds into sub-environment classes, relating this scheme to geometries;
  • To calibrate outcrop, core, and well facies, and link to architecture where possible.
