After the Welaco temperature survey was completed for TG52-7, preparations were completed for a controlled airlift test. This test was completed in the period from 19-20 September 2003 for some 23 hours. The well produced steady state flow of about 320-325 gpm at a wellhead temperature of 126.7degrees C (260degreesF). This production rate is equivalent to about 162,000 pounds per hour, with the production temperature producing usable heat content of about 26 million Btu per hour, or about 2.5 MWthermal. Because of excessive friction loss in the small diameter well bore (6-3/8-inch) resulting from turbulent flow caused by the airlift, the flow rate attained is not considered to be representative of likely resource potential. A larger well casing with mechanical pumping should produce higher yields.
