Well correlation

Figure C1 Location of the well/borehole correlation panels

Well correlation panels hung on the base of the Lower Limestone Formation (Hurlet Limestone) highlight the differing stratigraphic intervals drilled and the lateral variability of the Carboniferous succession (Figures C2-C6). The influence of igneous activity is striking, with numerous igneous sills and volcanic intervals encountered. Table 2 summarises the depths and thicknesses in key wells and boreholes used in this study.

The correlation of the Limestone Coal and Lower Limestone formations above the Hurlet Limestone is usually fairly straightforward, well studied and well constrained by data, though the precise assignments of named limestone and coal beds can be problematic where there is faulting and a lack of macrofaunal data. Lateral thickness variations are common, for example the Black Metals Member marine band reaches 164 ft (50 m) thick on the northern side of the Central Coalfield contrasting with less than ten feet (a few metres) thick in parts of the Midlothian Coalfield.

Correlation in the Strathclyde Group is more challenging due to laterally variable sedimentary and volcanic strata, laterally changing nomenclature, less constraining data and the possible effects of volcanism on biostratigraphically important faunas and floras.

Some of the volcanic strata are fairly well defined spatially by map, borehole/well and geophysical (magnetic) data (e.g. parts of the Kinghorn and Bathgate Hills volcanic formations) and some ashes are observed semi-regionally (e.g. Barracks Ash). However, as a result of limited data and likely complex volcanic geometries, in most cases the lateral extent of volcanic formations in the subsurface is poorly defined.

Stratigraphic interpretations Given the importance of stratigraphic interpretations to the modelled depth surfaces and eventual rock volumes of prospective shale resource, the interpretations on well composite logs and in well reports were examined. In some cases a revised stratigraphic interpretation to that on the composite log was made using biostratigraphy information (from the well report or in BGS records), extensive BGS knowledge of Carboniferous stratigraphy or core logging of wells at the time of drilling (e.g. South Fod 1) and BGS or published information on the character and age of igneous rocks. A summary of where BGS interpretations differ from the company composite log, or where particular interpretations are emphasised is given in Table 1.

In addition the well correlations utilise the most recent rather than historical terminology (see Appendix B for equivalence).

Well Revised stratigraphic interpretation Salsburgh 1A As in BGS Falkirk Memoir (Cameron et al. 1998), but with the interpretation of

Devonian microgranodiorite intrusion at base of well after Phillips & Browne (2000). Leven Seat 1 Nearly 1,970 ft (600 m) thick, fine-grained basalt (hawaiite to trachybasalt) and tuffs

containing interbedded TC zone sedimentary strata interpreted as Salsburgh Volcanic Formation and Gullane Formation equivalents. Presence of the top part of the Calders Member shows volcanism ended before that in Salsburgh 1A and 2. ?Pu zone strata beneath volcanic rocks correlated with the Inverclyde Group (Clyde Sandstone/ Ballagan Formation).

West Calder 1 The large proportion of ash in the mudstones at same stratigraphic level as the Salsburgh Volcanic Formation in Leven Seat 1 (7 km to SW) are interpreted as basinward equivalent of active extrusive volcanism.

Rashiehill (BGS borehole)

The interpretation of the volcanic rocks follows Anderson & Francis (1963) and Cameron et al. (1998), i.e. rocks of the Clyde Plateau Volcanic Formation at the base of the borehole are overlain by younger rocks of the Bathgate Hills Volcanic Formation.

Inch of Ferryton 1 Interpretation taken from an unpublished BGS petrology report to include Pathhead Formation between 5,663 - 5,898 ft and to correlate the Strathclyde Group (5,898 - 6,360 ft) with the Sandy Craig Formation. Strata from 6,800 to 7,800 ft dominated by Devonian volcanic rocks.

South Fod 1 Beneath the Burdiehouse Limestone – part of the Calders Member, faulted to TC zone Gullane Formation at 2,860 ft. Below this the strata are similar to that in the Rosyth-Dalgety Bay area, including the Charles Hill Volcanic Member at 4,600 ft. An undifferentiated Strathclyde Group is interpreted between the Charles Hill Volcanic Member and the tuff/basalt of Carboniferous character at the base of the well.

Rosyth 1 The top of the Gullane Formation is interpreted at 2,490 ft based on BGS palaeontology records and regional stratigraphic correlations.

Lathalmond 1 Re-interpretation of the well beneath 374 ft to West Lothian Oil-Shale strata, with numerous intrusive sills, plus volcanic strata correlative of the Kinghorn Volcanic Formation. Due to the thick igneous succession, the lack of available biostratigraphy, and thickness of Visean successions to the south-east, the base of the well is interpreted to remain in the Strathclyde Group (not reaching the Inverclyde Group as indicated on the company composite log).

Milton of Balgonie 1 The basal part of the well has been re-interpreted with changes in base Pathhead, Sandy Craig and Pittenweem formations, and the inclusion of Anstruther Formation compared to the composite log. This was based on advice and a graphic log drawn by M. Browne who was present at the time of drilling, and incorporating all the palynology and biostratigraphy.

Firth of Forth 1 The Pittenweem Formation is believed to extend from 4,877 ft to the TD of the well (i.e. the Anstruther Formation is not reached).

Blackness 1 and Easter Pardovan 1

The top of the Gullane Formation has been re-interpreted in both wells. Towards the base of both wells are volcanic rocks which could correlate with the Charles Hill Volcanic Member as seen in the South Fod well and on the Fife coast.

Carrington 1 & Stewart 1

The position of the top Gullane Formation has been estimated by correlation with Midlothian 1 (the latter being biostratigraphically constrained, Neves et al. 1973).
