|- 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&nbsp;—&nbsp;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&nbsp;ft maps/surface.<br>
Densify AOI curve to 3000&nbsp;m and filter to 750&nbsp;m, contour line densify to 1000&nbsp;m, smooth result 10 times, then use script if(Z<0) {Z=0;}. Some area required manual editing e.g. Bathgate Hills.<br>
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&nbsp;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&nbsp;m.<br>
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&nbsp;—&nbsp;1. Fit to boreholes by addition of control nodes&nbsp;2. Re-interpolate to fit back to other data away from boreholes&nbsp;3. Remove slivers along faults&nbsp;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.<br>
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,&nbsp;b,&nbsp;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.<br>
Imported shale percentage surfaces and TOC %, transferred properties to SGrids.<br>
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&nbsp;ft cut off surfaces and then SGrids for the 1000&nbsp;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&nbsp;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&nbsp;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.
| ALS
| August 2014
