Development of a Downhole Tool Measuring Real-Time Concentration of Ionic Tracers and pH in Geothermal Reservoirs

For enhanced or Engineered Geothermal Systems (EGS) geothermal brine is pumped to the surface via the production wells, the heat extracted to turn a turbine to generate electricity, and the spent brine re-injected via injection wells back underground. If designed properly, the sub...

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

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...

Geogenic Helium Release from Rock Fracture

In this project 38 uniaxial compaction tests were conducted at Sandia National Laboratories with 7 different rock types. During these tests, we created a vacuum system and evacuated and measured all the helium that was released by the samples during crushing. The experimental file...
