A temperature gradient of 28°C/km was used (with a ground level temperature of 10°C) was used in the software processing. This is equivalent to the red dotted line shown in Figure 13, sourced from Busby et al., 2011<ref name="Busby 2011">BUSBY, J, KINGDON, A, and WILLIAMS, J. 2011. The measured shallow temperature field in Britain. ''Quarterly Journal of Engineering Geology and Hydrogeology'', Vol.44, 373–387.</ref>.

[[Image:OR17037fig13.jpg|thumb|center|500px| '''Figure 13'''    Temperature data for the wells in this study plotted with regional data. Pale blue arrows represent the correction of the maximum wireline recorded temperatures for the time since drilling mud circulation ceased. Data point and trend codes are listed in Table 15. ]]
