  Plate model Radiometric data • Age • Representation Well data • Environment • Facies Seismic facies Cross sections Structure Published paleogeo-graphy Check that it makes sense Revisit data and model to identify problem. Create Paleo-geogra-phy Yes New data Check that it makes sense Wait for new data
• 4.
  • Based inESRI ArcMap • Uses PaleoGIS for creating plate reconstructions • Plate reconstructions based on PLATES database • Data for paleogeography based on CBTH database
• 5.
  • Compiled from publications • Georeference maps and digitize well locations • Use a look-up table with detailed information for each well
• 6.
  • Wells haveindividual ID acting as table key • General information • Source • Figure – link function • Data shown

  • Seismic linesare digitized from georeferenced maps • SEGY Seismic lines are interpreted
• 14.
  • Seismic faciesare classified • Using the seismic locations, facies are mapped by age

  • Be sureto take topology into account • Consider creating polylines first and converting to polygons to avoid gaps and overlaps • After drafting and checking, the lines can be smoothed for more artistic rendering of the area • Lines are converted to polygons • A consistent naming and symbology system is applied Image removed – For CBTH sponsoring companies only
