<br />GEOPHYSICAL LOGS <br />Geophysical logs for each hole consist of natural gamma (G), spontaneous <br />potential (SP), and resistivity (RES), which were measured with one probe, <br />and density (DEN), which was measured with a separate probe. Where fluid <br />level within the drill hole changed during logging, two fluid levels were <br />recorded on the log. Only one fluid level, that measured by the natural-gamma <br />spontaneous-potential resistivity probe, is listed in the log headings in <br />this report. Geophysical loge were reduced to 20 percent of the original <br />size, and the logging scales listed in the log headings have been changed <br />accordingly. The geophysical logs are oriented so that higher gamma and resis- <br />tivity and lower rock density readings are recorded to the right. The only <br />exception to [he above is the log for hole E-23 (see log on p. 66). The <br />aquifer depth intervals and the quantity of wa[erflow (gal/min (GPM)) from <br />drillers' logs are shown on the log headings. <br />LITHOLOGIC LOGS <br />Lithologic logs were made by adjusting descriptions of 5-foot cuttings <br />intervals to correspond with the geophysical logs. <br />DRILL-HOLE DEPTHS, DIAMETERS, AND LOCATIONS <br />Depths of the drill holes range from 40 feet to 800 feet and the diameter <br />of all holes is 4-3/4 inches. Locations and elevations are approximate. <br />CORE HOLES <br />Seven of the drill holes (J-2, J-6B, E-7, G-9, J-14, G-16, and E-23) <br />were twin drilled for the purpose of coring the Sudduth coal bed. Core <br />samples have been submitted to the U.S. Bureau of Mines for proximate <br />and ultimate analyses, B[u/lb heating values, forms of sulfur present, <br />and percent ash.
