Development of a Downhole Tracer and pH Measurement Instrument for Application in Geothermal Wells

Sep 11, 2013
1.8 MB
Publicly accessible
Due the high temperature and pressure conditions found in geothermal wells, tracer studies designed to elucidate properties of geothermal reservoirs are traditionally conducted by pulling liquid samples from the wellhead. These samples are then sent off for analysis in a fixed lab...
