Notes
In 1978, the Walker "O" No. 1 well at Terminal Geyser was drilled to 1222 m, all in volcanic rocks (Beall, 1981). Temperature-log profiles made 10 months after drilling completion show an abrupt temperature rise at _183 m, a maximum temperature of 176 degrees C at 610 m, a significant temperature reversal below 610 m, and a bottom hole temperature of 124 degrees C. Temperature reversals such as this generally indicate that the well has penetrated a lateral outflow plume of thermal water (Goff et al., 1988).
