Software used
- GOCAD® version 2.5.2 and GOCAD® v2009
- ArcGIS 9.3
- MS Excel
Model workflow
The following workflow was used to generate the Weald Basin Model:
- Compiled all raw data into a GIS: W:\Teams\UKGF\RegionalLithoframe\Data\Weald\weald.mxd
- Imported all fault traces, outcrop data and structural contours for each horizon into GOCAD®.
- Additional data added included the CEH DTM data points (See Model datasets)
- A raw surface (uncut by faults at this stage) for each horizon was modelled using a combination of the structural contours and outcrop which had elevation values applied from the DTM surface data.
- Every fault trace was draped onto its corresponding surface using the ‘Transfer Property by Vertical Projection’ tool and then following the methodology established in Fault sticks and Fault center lines, the fault plane was constructed.
- Once all of the faults had been constructed, branch contacts were established between the faults using the Structural Modelling workflow.
- The faults were then used to cut the raw surface horizons using the ‘Horizon-Fault Contact Modelling’ in the Structural Modelling workflow.
- Fault contacts and surface horizons were either edited using the Structural Modelling workflow parameters or manually using the tools available in GOCAD®
- Surfaces were then fitted to crop using the ‘Border on curve’ surface constraint.
- Any surface intersections were then removed using the ‘Remove crossovers’ dialogue.
