OAR 690-230-0090
Water Temperature Measurement

The water supply well report prepared for any low-temperature geothermal well that is tested by pumping water from the well, shall include the temperature of the fluid as measured at the discharge point at the beginning and end of a timed production test as well as the maximum fluid temperature attained during the test. Bailing or pumping the well are acceptable methods of withdrawing water from the well during the test. Air testing is not acceptable.

(2)

The well report prepared for any low-temperature geothermal well that is tested by pumping water into the well shall include the maximum temperature in the borehole and its corresponding depth.

(3)

The well constructor is required to provide the temperature data on the water well report. The Director may use other temperature data in making the final determination of the bottom hole temperature.
