The GOCAD<sup>®</sup> structural workflow manager (GOCAD<sup>®</sup> version 2009.4) was used as standard to create a fault model and faulted horizon surfaces.

During the faulted horizon modelling, data points within a tolerance of 200 m of faults were excluded. Some additional manual exclusion of seismic pick data points was made close to faults where the faults had a more complex geometry than the planar structures modelled.

Manual editing of fault-horizon contacts was necessary in some cases to create a more consistent throw. Horizon crossovers were also removed manually. Control nodes were inserted at borehole/well data points ([[OR/14/050 Model datasets #Seismic data |''see'' Seismic data]]). Edits were also made such that horizon surfaces were:

* ''deeper than'' boreholes proving the modelled stratigraphic units but not reaching the base (e.g. total depth (TD) within LSC)
* the base Limestone Coal Formation was ''deeper than'' The Coal Authority deep coal mining dataset ([[OR/14/050 Model datasets #Mine plan data |''see'' Mine plan data]])
* the base West Lothian Oil-Shale Formation was ''deeper than'' contours on the Burdiehouse Limestone given in Mitchell and Mykura (1962)<ref name="Mitchell 1962">MITCHELL, G H, and MYKURA, W. 1962.
