Residential, preheat tank solution, use average tank temperature of 130F plus the local EWT, divided by 2.25. For example if EWT is 70 then use tank temperature as 70F+130F/2.25=89F. WebNov 18, 1997 · Geothermal wells can sustain casing damage very early, even during drilling operations, due to internal casing wear. This can be related to drilling pipe rubbing against the casing, which occurs mainly in deviated/directional wells when the rate of angle change with depth is greater than 5 degrees/33 m (Fig. 9.16).
