Work in progress: closures and hydrocarbon contacts
Experimental and paused, not part of the base case. Partly digitised from a figure; see docs/contacts-structure.md.
Closure analysisHighs and spill points from the 25 m grid. Where the surface could hold a contact, not a proven trap.
Tentative fillWhat the surface alone would add beyond the provided limits.
Contact case
Contact coloursGeostandard: oil green, gas red. Not colour-vision safe.
