  3. My study area (red box on the map below) is in the Viking Graben Province (yellow polygon) of the North Sea Graben System, in the northern North Sea. The green polygons in the map represent oil fields. http://www.exprodat.com/Blogs/blog_Creating-Geological-Block-Diagrams-2.htm Next I wanted to fill the spaces between each layer in order to produce a block unit for each geological period and epoch; this also returns values for the volumes of each block unit. The first step was to convert the TIF grids to ArcGIS TINs (Triangulated Irregular Network), using the Raster to TIN tool: I took four TIFF grids for the study area, representing a sequence from youngest (top of the Eocene) to oldest (base of the Cretaceous), with the Paleocene layer between them.

  4. I then displayed the block units in ArcScene - displaying each block unit in turn allows for a detailed look at their general profile, and some top and base structural detail (below, left). Switching on all block units displays a block diagram (below, right). I then made the Cretaceous block semi-transparent, so that I could view the base of the block, and added oil reservoir accumulations (again processed using the Extrude Between tool to place them at the Base Cretaceous) trapped at the contact between the Upper Jurassic and the Base Cretaceous seal along fault footwall topography.

  5. I then added the wells in the area and some borehole data, allowing us to partly validate our blocks – the boreholes intersect the oil fields that they’re tapping!
