|- style="vertical-align:top;"
| MVS2012existing_v2009_3.gprj
| Existing model project used to examine additional faults to be included in DECC model (by incorporation of regional fault network from Clyde Catchment model, Clyde Volcanic models etc).
| ALS
| 9/1/14
|- style="vertical-align:top;"
| Minedata_surfaces.prj
| Used to compile data on Upper Hirst coal (URH) in ULGS to define shape of Kincardine Basin from borehole and mining data and outcrop — very rough extent and quick fault modelling done of new faults assuming 60 degree dip. To import to Landmark to aid seismic interpretation.
| ALS
| 30/1/14
|- style="vertical-align:top;"
| CPV.prj
| Used to compile data extracted from the CPV GSI3D models defining top and base CPV as well as LWM and LLGS and LSC.
| ALS
| 06/02/14
|- style="vertical-align:top;"
| Thick.prj
| Used to contour the thickness of the BKME, and also contour the depth-maturity surfaces.
| ALS
| 25/3/14
|- style="vertical-align:top;"
| bULGS_data.prj and four more
| Created Gocad projects to collate data for each modelled surface (bULGS, LSC, LLGS, WLO, GUL). Boreholes base and deeper than, extents etc added in.
| ALS
| 2/4/14
|- style="vertical-align:top;"
| Faultmodel_v1.prj
| Gocad project to collect existing modelled fault surfaces and to start modelling new ones. Updated 29/4 with all working fault data.
| ALS
| 3/4/14 and 29/4/14
|- style="vertical-align:top;"
| Shalepercentagemaps
| Project with the % shale and % shale >50 ft maps/surface. 
Densify AOI curve to 3000 m and filter to 750 m, contour line densify to 1000 m, smooth result 10 times, then use script if(Z<0) {Z=0;}. Some area required manual editing e.g. Bathgate Hills. 
Use the versions ''without'' the Shpercent in front.
| ALS
| 8/4/14
|- style="vertical-align:top;"
| Alldata.prj
| Sorting out seismic data and draft unfaulted surfaces.
| ALS
| 24/4/14
|- style="vertical-align:top;"
| Faultmodel_v2.prj
| Cleaned, contacted faults to be used. Outline curves added and edited so outside basin bounding faults. These versions not edited for contact errors (see v3).
| ALS
| 29/4/14
|- style="vertical-align:top;"
| Faultmodel_v3.prj and v4
| Faulted surfaces made. Regions made close to faults and where fault not fitting well for data exclusion by doing fault calculation and then manual edit. Exclusion distance 200 m. 
Moved to v4 due to a crash.
| ALS
| 30/4/14
|- style="vertical-align:top;"
| Faultmodel_v5.prj
| Used this project to start horizon editing process — 1. Fit to boreholes by addition of control nodes 2. Re-interpolate to fit back to other data away from boreholes 3. Remove slivers along faults 4. Fault-horizon edits.
| ALS
| 4/5/14
|- style="vertical-align:top;"
| Faultmodel_v6.prj
| Manual edits for ‘deeper than’ boreholes etc and overlap with rockhead.
| ALS
| 4/5/14
|- style="vertical-align:top;"
| Faultmodel_v7.prj
| Manual editing of overlap surfaces. Added Gleniffer-Castlemilk Fault dipping at 60° to N.
| ALS
| 4/5/14
|- style="vertical-align:top;"
| Faultmodel_v8.prj
| Cleaned project for model QC check. Added curves for making holes after model checked. 
Post-check corrections on 7/5, checked overlaps, isopachs and made holes.
| ALS
| 6/5/14
|- style="vertical-align:top;"
| Faultmodel_v9.prj (saved as 9aa then 9ab when crashed)
| Cut horizons by depth-cut off and other work for volumetric estimation.
| ALS
| 8/5/14
|- style="vertical-align:top;"
| Faultmodel_v10S grids
| Cleaned a lot of data out. Made SGrids of the four volumes using the stratigraphic surfaces and depth cut-off. Used 350*350*75 divisions on AOI. This is coarse compared to the mine data detail but finer than TIN spacing so gives a good representation of the volume.
| ALS
| 11/5/14
|- style="vertical-align:top;"
| Skua_volumes_fromv10.spr j and subsequent versions a, b, c (crashes, version c should be used)
| In SKUA. Brought over SGrids from fault model v10. Imported bounding polygons for the basal unit as ‘lease boundary’ to exclude areas of model unwanted eg GUL western area. 
Imported shale percentage surfaces and TOC %, transferred properties to SGrids. 
Calculated net shale volumes using reservoir volumetrics. Calculated net shale thicknesses as in oil and gas regions for each unit and exported via a pointset, for the mining-related depth cut off.
| ALS
| 11/5/14 and on to 31/05/14
|- style="vertical-align:top;"
| Faultmodel_v11_1000ft.prj
| Created project for Mike McCormac who created combined depth and 1000 ft cut off surfaces and then SGrids for the 1000 ft cut-off surface.
| MMCC/A LS
| 05/06/14
|- style="vertical-align:top;"
| DECC_MVS_SKUA_mode l.sprj and DECC_properties_MVS_S KUA_model.sprj
| Mike McCormac used to calculate volumes for 1000 ft cut off and then regions for oil and gas extents.
| MMCC
| 12/06/14
|- style="vertical-align:top;"
| Curveediting.gprj
| Simplifying extent curves for 1000 ft oil and gas.
| ALS
| 16/06/14
|- style="vertical-align:top;"
| NGM_cleaned version_faultmodel_v9ab.pr j
| Cleaned copy of the final Gocad project containing the complete 3D geological framework model, for submission to NGM.
