WebMar 10, 2016 · The Earth's geothermal gradient averages about 1.4°F/100 ft [2.55°C/100 m]. At this average gradient, the 350°F threshold would require a well depth in excess of 19,700 ft [6,000 m] (Figure 3). Downhole temperatures, however, are often affected by natural conditions or external influences.
