Proceedings of a pressure transducer-packer workshop, June 25-28, 1991

The U.S. Geological Survey conducted its first Pressure Transducer-Packer Workshop in Denver, Colorado, June 25-28, 1991. Nineteen attendees from the Survey, Environment Canada, academia, and the private sector presented papers concerning their experiences with the use of transducers and packers in hydrogeologic investigations. Workshop partici- pants concluded that fixed-head packers are generally more reliable than other types and that there is a need for a wet/wet transducer for deep wells. The group recommended that simple downhole technology be used, that only rugged commercially available packers be purchased, and that it is imperative electrical connections and transducer electronics be kept dry.
