Key points

  • An integrated multidisciplinary approach is used to differentiate and characterise tidally swept shelfal sands of the ‘True Rogn’ relative to submarine apron sands of the ‘Rogn Equivalent’
  • 684 new biostratigraphic sample analyses across the Viking Group with core descriptions and petrography from 3 wells, plus special petrophysical interpretation of spectral gamma wireline logs using LogsStrat
  • Tremendous variability was observed in the completeness, stratigraphic & spatial distribution, hiatuses and thickness within the Viking Group
  • Integrated biostratigraphy and reservoir geology of the sandstone and claystone lithologies of the Late Jurassic Rogn, Spekk and Melke Formations
  • Investigated sub‐regional stratigraphic variability, geographic distribution of sands, reworking and microfacies/ palynofacies of the Rogn, Spekk and Melke Formations, as well as gross geological reservoir characteristics
  • Study completed during 2017; ready for delivery with all supporting data
  • Integrated micropalaeontology, palynology, petrophysics (for lithology and porosity) and sedimentology (new core description and sampling) has significantly improved stratigraphic resolution
  • 683 new quantitative micropalaeontology and palynology closely spaced; focused on cored intervals to provide a consistent, high-resolution database
  • Core descriptions undertaken, together with petrography of core samples

Deliverables

  • PetroStrat zonations and chronostratigraphy are interpreted and calibrated to GTS 2012
  • Integration of wireline logs with interpreted lithostratigraphy sensu NPD and MFSs sensu Charnock et al., 2001 with interpreted core descriptions and petrographic observations
  • Palaeoenvironmental interpretation based on microfacies, palynofacies, core sedimentology and log pattern interpretation.
  • Biostratigraphy and sedimentology driven sequence correlations of all the 17 study wells
  • Time-slice maps included
  • All new data are available graphically in soft copy as .pdf report and digitally , .csv files and StrataBugs .dex files as standard
