Clastic Sedimentology

Clastic Sedimentology

Oolithica covers every aspect of clastic sedimentology from aeolian, lacustrine, fluvial, deltaic, nearshore shelf and slope to basinal depositional settings.  Applied sequence stratigraphic methodology is used to model depositional settings and facies distribution in both time and also spatially within basins and prospects.  An understanding of the importance of sedimentary processes allows us to further extend our interpretations beyond the area of immediate data coverage, providing added value for exploration and reservoir modelling.

Our linked services include:

  • Outcrop description studies

  • Core description studies

  • Cuttings studies and reconciliation with e-logs

  • Seismic stratigraphy, facies & well data integration

  • Sediment provenance studies

  • Sediment transport vectors from outcrop and FMI / dipmeter interpretation

Much of our work is integrated with more specialist petrographic and biostratigraphic datasets to provide better rock property characterisation and chronostratigraphic constraint.

Typically we determine:

  • Depositional environment & setting

  • Depositional facies characterisation

  • Depositional facies modelling to characterise vertical and lateral relationships, scale and geometry

  • Stratigraphic trends both vertically and laterally

  • Sediment provenance and changes in provenance / rock properties

  • Documentation of diagenetic overprint

  • Calibration of rock properties with e-logs
