Summary of wells validated during fiscal years 1991 to 1992
The Well Validation Project was initiated in fiscal year 1990, with the intended purpose to evaluate wells on the Nevada Test Site. During fiscal years 1991 and 1992, a temperature/electrical conductivity logging tool was redesigned and a thermal-pulse flowmeter logging tool was developed. Seven wells were evaluated during this time period: USGS HTH {number_sign}1, UE-18r, UE-14b, HTH {open_quotes}E{close_quotes}, USGS Test Well B Ex., UE-1q, and UE-5n. The validation techniques used at each site varied depending on the site-specific objectives. Thermal-pulse flowmeter surveys were carried out in several of the wells with limited success. The thermal-pulse flowmeter was designed for boreholes 2 to 6 inches in diameter, most wells at the Nevada Test Site are generally much larger in diameter, 10 to 24 inches. Therefore, the thermal-pulse flowmeter was outfitted with an inflatable rubber packer, which constricts borehole flow through the thermal-pulse flowmeter, increasing the resolution. The thermal-pulse flowmeter can be outfitted with various-sized packers depending on the borehole diameter to be evaluated; these packers are commercially available. The packers are inflated with borehole fluid via a small submersible pump which was designed, built, and tested as part of this study.
