PDF Version Also Available for Download.

Description

On December 8, 1977, Gruy Federal, Inc. took over the C.D. Hopkins et al. No. 2 well, located near Jesup in Wayne County, Georgia, to be deepened and used for geothermal temperature-gradient measurements. The well was drilled from 4,009 to 4,341 feet, then diamond cored to 4,371 feet, 28 feet of core being obtained for analysis. After logging by the USGS District Groundwater Office in Atlanta, the well was terminated with 3 1/2 inch tubing to 4,386 feet. Scientists from Virginia Polytechnic Institute determined the bottom-hole temperature to be 60 C (140 F) at 1,331 meters (4,365 feet). Over the ... continued below

Over the interval 47-1,331 meters (154-4,365 feet) the least-squares temperature gradient was 29.3 {+-} 0.14 C/km (1.61 {+-} 0.25 F/100 ft).
