The North Vernon Formation consists of three reservoir intervals shown with the 8% porosity cutoff used for mapping the net thickness isopach in Figure 3. The upper and middle intervals are oil productive in these three wells. The thick Geneva Dolomite Member of the Jeffersonville Formation in well D has an average porosity of 27% but is water bearing in the Glen Ayr field.

The porosity of the upper reservoir zone, North Vernon Formation, in the Fry 29-2 well does not exceed the 8% porosity cutoff. Sample descriptions on the Fry 29-2 mud log are similar to the core descriptions in well A in the previous figure, demonstrating the continuity of the reservoir facies off structure.

Abstract The Dalradian Supergroup, comprising the Grampian (oldest), Appin, Argyll and Southern Highland (youngest) groups (Fig. 13) consists of lithologically diverse metasediments and typically mafic metavolcanic rocks. The supergroup is probably entirely late Precambrian in age and underlies an area of about 48000 km 2 in north and west Ireland, Scotland and Shetland. Neither the base nor the top of the Dalradian is seen but, taking the maximum thickness preserved for every group and making no allowance for tectonic thickening, it is calculated to have a total cumulative thickness of c. 25.5 km.
